2.6 Unpacking and Inspection

In the non-turn-key project, both the customer and the project supervisor (engineer from Huawei or cooperator) are required to be present at the unpacking site. If either



2-6

is absent at the unpacking site, the party who unpacks shall take the responsibility for any errors occurring to the articles.

In the turn-key project, it is the project supervisor and the order management engineer who unpack, check and accept, hand over the articles, and make a confirmation with signatures.

Before unpacking, both parties should check if the packing cases are damaged. If so, stop unpacking and contact the order management engineer at the local office of Huawei, waiting for the handling. Meanwhile, check if the quantity of cases on the site agrees with the packing list, if the place of delivery agrees with the actual installation place, and if the articles have been inversed during the transportation. If there is any disagreement, the project supervisor should feed back the Article Problem Feedback Form confirmed by the customer with a signature to the order management engineer at the local office within 3 days.

After all the above inspections are ok, unpack the cases to check and accept the articles.

There are two kinds of packages: wooden crate and cartons. The unpacking tools should be used accordingly.

2.6.1 Unpacking Wooden Crate

I. Overview of Unpacking Wooden Crate

Caution:

The wooden case is direction-oriented and should not be placed upside down. Otherwise, fatal damages would be caused to the product.

Wooden crate is used to package cabinets and batteries. A packaged cabinet is composed of wooden board, angle steel, tongue, and foam corner protector. Before unpacking the wooden crate, move the packing crate to the equipment room or nearby (if there is sufficient space), to avoid damage to the cabinet when moving the cabinet.

II. Operation Procedures of Unpacking Wooden Crate

The unpacking steps are as shown in Figure 2-1.

1) Insert the spanner into the tongue holes in the cover, and turn the spanner to straighten the tongues, as shown in Figure 2-1 (a).

2) Lift and remove the covers, as shown in Figure 2-1 (b). 3) Straighten the tongues in the surrounded wooden board, and then remove the

surrounded wooden board, as shown in Figure 2-1 (c). 4) When moving or lifting the cabinet, use both hands to hold the firm parts of the

cabinet, such as brackets or major frames, instead of other parts, such as cable brackets and cable fixing beam, to avoid damage to the cabinet or personal injury. Remove the lining boards of the cabinet on the installation site to avoid damage to signal cables and boards when moving or lifting the cabinet.

2.6.2 Unpacking Carton

The unpacking steps are as shown in Figure 2-2



2-8

Figure 2-2 Unpacking the wooden cartons

Generally, the carton is used to pack various boards, fibers, network cables, terminal equipments and other accessories. The board is placed in an antistatic bag for transportation. Inside the bag, there is a desiccant to keep it dry. The tool to open the carton is generally a paper knife.

Unpack the carton as follows:

1) Rip the adhesive tape along the joint seams using a paper knife. Be careful not to insert the knife too deep, avoiding damage to the boards.

2) Unpack the carton and take out the inner goods.

Caution:

If the equipment is moved from an environment with relatively low temperature and humidity to one with relatively high temperature and humidity, do not unpack it until at least 30 minutes later. Otherwise, the moisture may condense on the equipment surface and thus cause damage to the equipment.

Antistatic measures should be taken for unpacking boards so that boards will not be damaged.

2.6.3 Acceptance and Handover

I. Acceptance

The inspector should carefully check and accept the articles piece by piece with reference to the name, type and quantity of the articles stated on the packing list.

The acceptance of articles mainly includes the following aspects:

Appearance inspection: check if there are any defects on the appearance of the rack, if the rack is secure and fast, if there is any looseness or damage, if the



2-9

identification is legible, and if the nameplate and decorating plates are completely installed and if they meet the use requirements.

Integrity inspection: check if all the parts and accessories necessary for the installation of racks are matching and complete.

Inspection of computer terminal: check if the display, keyboard and mouse are all ready and if there is any damage on them.

Board inspection: check if the board type agrees with the description in packing list, and if there is any broken printed circuit boards or any components detached from the board.

Note:

The project supervisor should take a major role in the inspection of equipment and components whose electric characteristics are apt to be affected.

The inspected articles should be placed by types. The packing cases after opened should be saved until the customer signs on the packing list.

II. Handover

After the acceptance, both parties must sign on the “Packing List” to confirm that there is no problem with the articles. After that, the articles are handed over to the customer.

During the inspection, if “outstanding articles” is stated in the packing list, it is necessary for the project supervisor to feed it back to the order management engineer at the local office. The order management engineer will urge the relevant department of Huawei to deliver the outstanding articles as soon as possible. Then both parties sign on the packing list. For any short, wrong, or extra shipment, or for any damage of articles, both parties should sign the “Unpacking Inspection Memo” and “Packing List”. Moreover, the project supervisor should fill in the “Article Problem Feedback Form” and feed it back to the order management engineer at the local office within 3 days. The project supervisor should also be responsible for well keeping the original condition of articles with problems as well as the inner and outer packing, for future investigation and verification.

If the articles are damaged or lost due to the improper keeping of the customer party after the customer accepts them, the customer party shall bear all the responsibility.

During the implementation, if there are any damaged parts or any other parts need to be replaced or re-issued, the project personnel should carefully fill in the “Article Problem Feedback Form” and feed it back in time to the article manager at the local office to put it on records.

Chapter 3 Installing Cabinets



Introduction to Cabinet Installing Cabinets on ESD-Preventive Floor Installing Cabinets on Cement Floor

3.2 Introduction to Cabinet

The UMG8900 adopts standard 19-inch N68-22 cabinet, with flexible and simple structure, and powerful versatility. The dimensions are 2200 mm (height with door lintel) x 600 mm (width) x 800 mm (depth). Five cabinets can satisfy the requirements for full configuration of the UMG8900.

According to different equipment rooms, a cabinet can be installed on the cement floor or ESD-preventive floor. When two or more cabinets are installed in the same row, they must be combined and fixed.

Note:

Wear clean gloves when touching the surfaces of cabinets or frames.

3.3 Installing Cabinets on ESD-Preventive Floor

3.3.1 Introduction to Supports and Floor Holder-Slide Rail Assemblies

I. Introduction to Supports

If N68-22 cabinets are installed in equipment room with ESD-preventive floor, N800 series supports are used.

Supports, made of welded steel plates, are used to block the cabinets up, thus facilitating floor paving and cabling. Before the whole set of equipment is grounded,



3-2

insulation plates must be installed under the supports, and insulating coverings must be added to the expansion bolts to satisfy the insulation requirements.

N800 series supports have four kinds of components, of which three kinds are height adjustable and one kind is of fixed height.

The appearance of the N800 supports is shown in Figure 3-1. The height adjustment range of each kind of component is shown in Table 3-1.

Note: The height of floor refers to the distance between the upper surface of ESD-preventive floor and the cement floor.

The height of N800 series I, II and III components can be adjusted within their adjustable ranges, which is realized by means of the relative move of upper beam and lower beam.



3-3

N800 IV component is the support of fixed height, which is applicable to ultra-high and ultra-low floors. The lowest applicable floor height of this component is 100 mm.

II. Introduction to Floor Holder-Slide Rail Assemblies

Floor holder-slide rail assemblies include floor holder, holder fixing component, and slide rail. Floor holders are used to support the floor around cabinet, and can be divided into front and back floor holders, and side floor holder. Holder fixing components are installed under slide rails, and they are used to connect slide rails and front and back floor holders.

Slide rails are used to connect cabinet and supports, and to move the equipment and adjust the equipment positions. They can join two supports and a cabinet together to keep the cabinet in a horizontal line and the connection stable. Due to their elasticity, the slide rails can absorb the vibrations.

The appearance of a slide rail is shown in Figure 3-2.

3.3.2 Amount of Supports, Floor Holders, and Slide Rails

I. Amount of Supports

To connect cabinets, 2N mode is used to determine the number of supports to be used. That is, each N68-22 cabinet uses two supports, and N cabinets in a row need 2N supports, as shown in Figure 3-3.



3-4

Figure 3-3 Installing N800 support

II. Amount of Floor Holders and Slide Rails

Each cabinet has one set of floor holder-slide rail assemblies, which is delivered together with the supports. Each set of floor holder-slide rail assemblies include two slide rails, two side holders, one front floor holder and one back floor holder.

Each cabinet needs two holder fixing components, one front floor holder, and one back floor holder, and each cabinet row needs two side floor holders, even if there is only one cabinet in a row.

III. Drilling Holes

To fix supports onto the ground with the M12 expansion bolts, it is required to drill holes for the expansion bolts using a percussion drill with bit φ16.

To drill a hole, do as follows:


1) Keep the drilling bit vertical to the ground and hold tight the drillstock to make holes 52 mm to 60 mm deep. The depth of the holes must be within 52 mm to 60 mm. Otherwise the expansion bolts cannot be fastened. Make sure that the depths of all holes are the same.

2) Clean the dust inside the holes with a vacuum cleaner. 3) Measure the depth to make sure that the depths of all holes are the same.



3-9

If the ground is too hard or smooth to settle the drill bit, punch a sample pit first for easy drilling.

Drawing lines and drilling holes are the fundamental work for hardware installation. Good quality is the prerequisite to guarantee the quality of the overall installation. If the accuracy is not high enough, the future work will be greatly affected.

Note:

The depth of drilled hole must be 52 mm to 60 mm. A depth less than 52 mm or more than 60 mm will cause the expansion bolt unable for normal installation and fastening.

3.3.5 Installing Supports and Slide Rails

I. Installing Expansion Bolts

Before fixing expansion bolts, clean up the dust inside and around the holes with a vacuum cleaner. Measure the distance between the holes and place the supports to check whether the supports and holes match exactly. For the holes with big deviation, plan and drill new holes before installing expansion bolts in them.

To install an expansion bolt, do as follows:

1) Take expansion tube and nut off the expansion bolt, and put them vertically into a hole after the guiding rib on the expansion nut has been inserted in to the guiding slot.

2) Strike directly on the expansion tube with a rubber hammer until it is completely driven into the ground.

If there is no DC power distribution cabinet in the equipment room, connect the power cables from the -48V1 and -48V2 connecting terminals of the N68-22 cabinet directly to the -48 V DC negative line bank of the DC switchboard or DC power, and connect the power cables from the GND connecting terminals of the N68-22 cabinet directly to the -48 V DC positive link bank of the DC switchboard of DC power. The PGND connecting terminals must be connected directly to the nearest protection grounding bar in the equipment room. The protection grounding cable uses green and yellow plastic insulation copper core wires whose core area is the same as that of power cable.

5.6.2 Core Areas of Power Cables and Protection Grounding Cables

The power cable from the DC power distribution cabinet to a N68-22 cabinet includes –48 VDC cables (blue) and RTN cables (black), which, together with protection grounding cable (green-yellow), are delivered with the equipment.

Their core areas are shown in Table 5-2.

Table 5-2 Core areas of cables from DC power distribution cabinet to UMG8900 cabinet

Name Specification

–48 VDC cable (blue) 25 mm2 copper core — dual

RTN cable (black) 25 mm2 copper core — dual

Protection grounding cable (green-yellow) 25 mm2 copper core

Note:

The cross area of power bus cable from DC switchboard to DC power distribution cabinet is designed according to the parameters such as loop length of the power bus cable, terminal load payload capacity for the engineering and design voltage drop. If the core area of all available power cables cannot meet the design requirements, it would be considered to connect two or more power cables in parallel. For example, if there is only 120 mm2 power cable, but a 240 mm2 power cable is required, you can use two 120 mm2 power cables in parallel connection as one power bus cable.

5.6.3 Installing Power Cables and Protection Grounding Cables

If DC power distribution cabinet is provided together with the UMG8900 equipment, it is required to install and connect it to the nearby protection grounding bar offered by the customer through protection grounding bus cable before installing power cables and protection grounding cables from DC power distribution cabinet to the UMG8900 cabinets.

Note:

Before connecting power cables and protection grounding cable, measure the distance between protection grounding bar and power distribution cabinet, and that between DC power distribution cabinet and connecting terminals of the power distribution frame in the cabinet. Use cables that are long enough to avoid shortage during actual wiring. If a cable is not long enough, stop your work and replace it with a new one. Do not splice cables by connectors or soldering.

It is required to stick labels on both ends of power cables, and a label must be stuck at the place where it is 30 mm apart from the root of the cable.

The connection of power cables and protection grounding cables from the DC power distribution cabinet to the N68-22 cabinets is shown in Figure 5-9.

1) Insert the cord end terminals (as shown in Figure 5-10) of the two –48 VDC cables into the connecting terminals marked “–48V1” and “–48V2” on the power distribution frame in the cabinet. Connect the other ends of the two cables to the output connectors marked “–48V1” and “–48V2” in the DC power distribution cabinet, for example, the “–48V1” and “–48V2” power cables in the third cabinet must be connected to the third output connector of “–48V1” and third output connector of “–48V2” in the DC power distribution cabinet.

Figure 5-10 Power cable cold end terminal

2) Connect the black RTN cables to the connecting terminals marked “RTN” on the power distribution frame of the cabinet, and then connect the other ends of the black grounding cables to GND grounding bar in the DC power distribution cabinet.

Note:

The connecting terminals of DC power distribution cabinet are assigned in terms of the principles “first up, last down” and “first left, last right”. That is, for –48V1 and –48V2 connecting terminals, use the upper group first, then the lower group; for the upper group, use the connecting terminals from left to right (from the front view) one by one. The connecting terminals of positive line bank and lightning protection ground are used from left to right in sequence. In other cases when power cables are led from DC power distribution cabinet (for example, to connect protection grounding cables for a terminal), reverse principle is applied, that is, connecting terminals are used from down to top and from right to left, to facilitate future expansion and connection.

If only DC switchboard is configured in the equipment room, do as follows:




5-15

3) Connect the power cables led from –48V1 and –48V2 connecting terminals of the UMG8900 cabinet to –48 VDC negative line bank of DC switchboard (or DC power supply);

4) Connect the power cable led from GND connecting terminal of the UMG8900 cabinet to –48 VDC positive line bank of DC switchboard (or DC power supply);

5) Connect the protection grounding cable led from the PGND connecting terminal of the UMG8900 cabinet to the protection grounding bar nearby provided by the customer. The cable material must be the green and yellow plastic insulation copper core wire whose core area is the same as that of power cable.

5.6.4 Requirements for Installing Power Cables and Protection Grounding Cables

I. Laying Power Cables and Protection Grounding Cables at N68-22 Cabinet Side

1) When downward cabling is used, lead the power and protection grounding cables into the cabinet through the cabling holes at the bottom of the cabinet. Lay the cables along the cabling troughs on the side columns of the cabinet until they reach the top of the cabinet through the cabling holes in the top. The subsequent layout and connection are the same as those mentioned in upward cabling below.

2) When upward cabling is used, lay the power and protection grounding cables on the top of the cabinet. Connect the protection grounding cables to the grounding bolts, and then lead them out from the grounding bar that connects to the grounding bolts. Lead the power cables through the cabling holes at the top of the cabinet, and connect them to the corresponding connecting terminals in the power distribution frame.

3) To lay the power and protection grounding cables, straight and even appearance is required, and different colors must be separated, and the cables must be bound every 200 mm.

4) After the power and protection grounding cables are laid out, cut the rubber cover to match the size of the left space of the cabling hole.

II. Laying Power Cables and Protection Grounding Cables in DC Power Distribution Cabinet

To lay the power cables and protection grounding cable in the DC power distribution cabinet, do as follows:

1) Lead the power cables (settled according to colors) into DC power distribution cabinet through cabling holes in the top of the cabinet.

2) Bind them along the side columns.




5-16

3) After the cables reach corresponding connecting bars, bind them along the beam of the cabinet. Ensure that the cables are laid inside the cabinet with smooth and uncrossed appearance.

4) Keep proper redundancy for the cables, and cut out the surplus parts.

When you make an OT terminal for a cable, be sure to cover it with heat-shrinkable tube, solder it (soldering is not allowed when your make a cable with large core area), and shrink the heat-shrinkable tube.

When OT terminals are connected to GND copper bar and –48V wire post, add flat washers and spring washers, and arrange them in correct positions.

Note:

When power cables and protection grounding cable are laid outside cabinet, they must be bound separately. When cables are laid inside cabinet, power cables and protection grounding cable are bound separate from signal cables.

5.7 Installing Power Bus Cables between DC Power Distribution Cabinet and DC Switchboard

5.7.1 Introduction to Power Bus Cables

Power bus cables are used to connect DC power distribution cabinet and DC switchboard.

Generally provided by the customer, a power bus cable in the power room includes –48 VDC cable (blue) and grounding cable (black). The specifications of the power bus cables are determined according to the result of site survey.

5.7.2 Connecting Power Bus Cables

6.4 Requirements for Installing Signal Cables

6.4.1 General Requirements

The general requirements for installing signal cables are as follows:

Before being installed, each cable must be marked or have engineering labels at both ends to identify the cable. For detailed information, refer to Appendix B "Engineering Labels for Cables" of this manual.



6-4

Different types of cables, such as power cable, signal cable and protection grounding cable, must be separately bundled. When cables are laid inside cabinet, power cables and protection grounding cables must be bundled and placed along the inside cabling trough, while signal cables along the outside cabling trough.

When cables are laid in vertical directions, they must be bundled and placed along the side columns of the cabinet. When cables are laid in horizontal direction, they must be bundled and placed along cabling trough.

When power cables and signal cables are laid in groove, it is prohibited to bind them together, instead, a distance of at least 30 mm between them must be ensured.

Connectors must be secure and in good contact. Cables must be bundled to correct positions with proper tightness.

6.4.2 Method of Using Fiber Coiler

A fiber coiler is installed at the bottom of cabinet to coil the superfluous fibers.

The appearance of a fiber coiler is shown in Figure 6-3.

Figure 6-3 Appearance of a fiber coiler

A fiber coiler is a drawer-like component having guide rails at both ends. It can be pulled out of the cabinet from the back. To pull the fiber coiler out, loosen the two captive screws at both sides and then pull the fiber coiler out to a proper position along the guide rails.

When coiling optical fibers, be careful and do not force to do that to prevent fibers from being damaged. There must be proper redundancy to ensure that the optical fibers will not be stretched when the fiber coiler is inserted into the original position.

6.5.3 Installing Cascading Cables

I. Type and Appearance of Cascading Cables

Cascading cables include FE cascading cable, GE cascading cable and TDM cascading cable. FE cascading cable is crossover network cable, and GE and TDM cascading cables are optical fibers.

The appearance of a crossover network cable is shown in Figure 6-13.

Cascading optical fiber is LC fiber, as shown in Figure 6-14.



6-14

Figure 6-14 LC optical fiber

Note:

When two or more frames are configured, cascading cables are required. When two frames are configured, direct connection mode is adopted. If three or more frames are configured, a central switching frame is required to provide cascading boards to connect with the frames.


To prevent optical fibers from being damaged, cables and optical fibers must be laid separately. Colligate optical fibers with nylon straps. The curvature radius of the bending part of optical fibers must not be less than 35 mm and the surplus fibers must be rolled on fiber coiler.

III. Installing Cascading Cables

When two frames are cascaded, connect the main control frame and service frames directly with cascading cables. Between the NETs of the main control frame and of a service frame, use one pair of FE cascading cables and two pairs of GE cascading cables. Between TDM central switching network units (TNUs) of the main control frame and TDM convergence & link units (TCLUs) of a service frame, use three pairs of TDM cascading cables. The NETs, TCLUs and TNUs are configured in active/standby mode and the connection relationships are the same.

When three or more frames are cascaded, one of them functions as the central switching frame that has back link units (BLUs) used to implement cascading. The



6-15

connection method between the main control frame and the central switching frame is the same as that when two frames are cascaded, that is:

Use one pair of FE cascading cables and two pairs of GE cascading cables between the NETs of the main control frame and of a service frame

Use three pairs of TDM cascading cables between the TCLUs of the main control frame and the TNUs of the central switching frame.

The BLUs in the central switching frame provide cascading cable interfaces for cascading cables to connect to service frames. Every pair of BLUs can be cascaded with one service frame. Each BLU can be connected to the NETs of a service frame with one pair of FE cascading cables and two pairs of GE cascading cables, and to the TCLUs of a service frame with three pairs of TDM cascading cables. The extended control frame and the central switching frame are connected through FE cascading cable.

When the frames are fully configured, the connection relationships of cascading cables are shown in Figure 6-15..

When two frames are cascaded, the connection relationships are shown in Figure 6-16.

When three frames are cascaded, the connection relationships are shown in Figure 6-17.

6-20

III. Installing Internal E1/T1 Cables

The three main ways to connect the SSM with the UAM are shown as follows:

The SSM and the USM connect with each other directly by cables.

If there is no DDF rack in the machine room, the E1/T1 cable of the SSM can be connected with the corresponding E1/T1cable of the UAM by using coaxial cable conversion connectors.

The SSM and the UAM connect with each other by the DDF rack.

If there is a DDF rack in the machine room, the E1/T1 cables of the SSM and the UAM can be connected to the DDF rack by the jumper provided by the DDF rack.

The SSM and the UAM connect with each other through the SDH transmission equipment.

If the UAM is located at the remote end, the SSM and the UAM are connected to their respective transmission equipment by the E1/T1 cable. The transmission equipment at both ends are connected through the transmission network.

For details about the connection modes between the SSM and the UAM, refer to Appendix D “Connecting the UAM”.

For the detailed installation description of the UAM, refer to the series of UAM user manuals listed below:

6.6 Installing External Signal Cables

6.6.1 Installing Trunk Cables

I. Type and Appearance of Trunk Cables

There are two types of trunk cables used in the UMG8900, 75/120 ohm E1 trunk cable and 100 ohm T1 trunk cable. Both types adopt HD100PIN connectors with pin spacing of 1.27 mm, and each cable includes 16 channels of E1 or T1 signals.

The 75 ohm E1 trunk cable is 32-core coaxial cable with the impedance of 75 ohm, and the 120 ohm E1/T1 trunk cable uses 32 pairs of twisted pairs with the characteristic impedance of 120 ohm.

The appearance of a trunk cable is shown in Figure 6-20.


The length of the trunk cables and the type of the DDF are confirmed during the site survey. Because the external diameter of a single wire jacket is 1.95 mm and the external diameter of the insulation jacket is 1.05 mm, it is required to use corresponding connectors when the DDF is installed on site.

The length of the cables to be laid is determined during the site survey, and proper redundancy is required. If a cable is not long enough, you must replace it with other proper cable. In some special cases, you can use dedicated coaxial cable connector to splice cables, but soldering is prohibited.

Note:

It is not recommended to bundle trunk cables in cabling trough behind frame to facilitate board insertion.

III. Installing Trunk Cables

To install a trunk cable, do as follows:

1) Connect one end to the FE32 or FT32. 2) Connect the other end to the DDF.

Figure 6-20 shows the connection relationships of trunk cables, taking E1 cable (connected to FE32 board) as example.

6.6.3 Installing External Network Cables

I. Type and Appearance of External Network Cables

External network cables are used to connect the UMG8900 and local maintenance terminal (LMT), the SOFTX3000 device or another Media Gateway (MGW) device.



6-24

External network cables include straight through network cable and crossover network cable. Crossover network cable is used when a PC or MGC is connected to the UMG8900 directly. Straight through network cable is used when they are connected through HUB or Ethernet switch.

Straight through network cable looks the same as crossover network cable. They have shielded plastic crystal connectors at both ends and their cable materials are category-5 shielded twisted pair. They are only different in line assignment.

The appearance of the network cable is shown in Figure 6-13.


Network cable is laid through DDF and the length is determined according to the site survey. The installation and layout requirements are similar to those for trunk cable and clock cable.

III. Installing External Network Cables

For specific installation method, refer to construction documentation.

6.6.4 Installing External Optical Fibers

I. Type and Appearance of External Optical Fibers

You need to select a fiber connector according to the optical interface type of the opposite device that is connected to the network interface module of the UMG8900. Single-mode optical interface can only use single-mode fiber and multi-mode optical interface can only use multi-mode fiber.

The optical modules in fixed network gigabit 1-port optical fiber interface board (FG1O), fixed network 1-port 622M POS fiber interface board (FP1H), FS2L, FA4L and FP4L boards all adopt LC connectors and LC optical fibers are used correspondingly.

The appearance of the external optical fiber is shown in Figure 6-14.


Before connecting optical fibers, it is required to ensure the connector type and fiber type are applicable to the type of the adopted optical interface.

To lay the external fibers, it is required to use corrugated plastic tubes or other protection tubes to protect the optical fibers.



6-25

III. Installing External Optical Fibers

To install an external optical fiber, do as follows:

1) Lead the optical fiber out of the optical module interface on the front panel of FG1O, FP1H, FS2L, FA4L or FP4L.

2) Connect it to the external optical distribution frame (ODF) or external optical interface/transmission device.

For specific connection relationships, refer to the construction documentation.

The check on power supply for the cabinets and frames is to see whether there is short circuit in all output power lines from the DC power distribution frame, whether the input DC voltage to the UMG8900 cabinets is normal, whether the visual and audio alarm function of the frames in all cabinets is normal, and whether the input DC voltage to all internal components of the cabinets is normal. The check steps are described as follows.

1) Shut down the power supply of DC power distribution cabinet, and set all AC power sockets and switches to OFF. Set the multimeter to ohm range and check whether there is short circuit between power supplies (–48V1 and –48V2) of the DC power distribution frame and between grounds (BGND and PGND), and whether the power supply is disconnected from the ground. The hot wire, ground wire and neutral wire of every socket must not be shorted.

2) Set all the switches of the power distribution frame in the top of the cabinet to OFF, and then power on the DC power distribution cabinet. In the case of no load, use the multimeter to check whether the output of power supply is within the allowed voltage range (–57 V to –40 V). At this time, red “ALM” indicator on the power distribution frame should flash and the buzzer will give off audible alarm upon setting the ALARM switch to “ON”.

3) Set all the switches of the power distribution frame in the top of the cabinet to “ON” after making sure that there is no board inserted into the corresponding slot on the backplane. At this time, there should be no power alarm or audible alarm and the red WARN indicator should not light up. The fan frame should operate normally and there is no abnormal noise.



9-4

4) Check whether other devices in the cabinets are with power supply input of –48 V and their voltage is within the proper range (–57 V to –40 V). If everything is normal, the power supply is in good condition.

If any of the above items does not meet the requirement, find out the reason and perform troubleshooting before the power-on check.

The alarm indicators on the power distribution frame can indicate analog value alarm information and Boolean value alarm information. To analyze analog value alarm information, follow the method below.

1) Check whether there is alarm for analog values through the background, including voltage of the two power supplies, humidity sensor, and temperature sensor. Check whether the reported values are normal.

Item Default normal value

Voltage –42V to –58V

Humidity 5% to 90%

Temperature 5°C to 70°C

2) If the above values are normal, check whether the values are beyond the upper limit or lower limit configured in the background.

To analyze Boolean value alarm information, follow the method below.

1) Check whether there is Boolean value related alarm, including: Lightning protection fault of dual channel Power distribution output switch fault of four to eight channels Inverter fault of three channels Preserved Boolean value fault of three channels

2) Check whether the corresponding Boolean value detection is configured. If yes, check whether there is alarm for Boolean value and check whether the alarm is normal.

If Boolean value detection is not configured, execute alarm disabling/enabling command through the background to mask those Boolean values not configured

9.4 Performing Board Power-On Test

The working status of a board powered on can be known according to indicators on the board front panel. For the meanings of board indicators, refer to HUAWEI UMG8900 Universal Media Gateway Hardware Description Manual.

The steps to conduct the trial power-on check are as follows.

1) Check whether the input and output cables of –48 VDC power supply are correctly connected and whether the connection cables are firm.



9-5

2) Set all the switches on DC power distribution frame for the boards to “OFF”, and then insert the boards into the slots on the backplanes and fasten the front planes of the boards.

3) Set the power switches controlling the frames to “ON”. At this time, all board indicators should be normal. If the indicators of all boards do not light up after the power switches are turned on, it indicates no –48 VDC input or error of the input terminal connection. If the power switch jumps upon being closed, it means there would be short-circuit of payload or connection error on the output terminal (short circuit).

A.2.3 Installation Modes

The cabling rack can be installed in four different modes:

Install a suspender on the ceiling to hang the cabling rack (hereinafter referred to as the “suspension mounting mode”).

Install a bracket on the ground to support the cabling rack (hereinafter, referred to as the “ground supporting mode”).

When the cabling rack is placed against the wall, install a triangular support on the wall to support the cabling rack.

When the cabling rack passes over the cabinet, install a shockproof support or a ladder on the cabinet to support the cabling rack.

A.2.4 Cabling Rack Specifications

Cabling rack is made of cabling ladder, and cabling trough which is optional component.

The cabling ladder and the cabling trough have the following specifications:

200mm-wide cabling ladder matches the 200mm-wide cabling trough; 400mm-wide cabling ladder matches the 400mm-wide cabling trough; 600mm-wide cabling ladder matches the 200mm +400mm-wide cabling trough.

It is recommended to use 400mm-wide cabling ladder over the cabinet, and not to use cabling trough, to facilitate cabling and to improve the heat dissipation of the system.

A.3 Installing Cabling Rack

A.3.1 Installation Procedure

Caution:

The cabling rack must be insulated from the floor, ceiling and walls.

The procedure for installing the cabling rack is shown in Figure A-20.

A.3.2 Assembling Cabling Ladder

The cabling ladder uses channel-section steel and cross stays for form its framework. The channel-section steel functions as the vertical beams of the cabling ladder and the cross stays function as the horizontal beams. To assemble a cabling ladder, use fastener to connect the cross stays with the channel-section steel. The spacing



A-9

between two cross stays is 250 mm. Because the spacing between holes in the channel-section steel is 50 mm, install one cross stay every five trough holes. When the assembled cabling ladder is used for horizontal installation, the bolt head of the cabling ladder should face downward to ensure that there is no protrusion on the ladder surface and to facilitate the installation of cabling trough.

The basic structure of a cabling ladder is shown in Figure A-21.

(1) Fastener (2) Cross stay (3) Channel-section steel

Figure A-21 Basic structure of a cabling ladder

If a longer cabling ladder is required, you can join several cabling ladders in an “end to end” fashion. The channel-section connecting piece is used to connect ladders, as shown in Figure A-22. If the length of a cabling ladder is not an integral multiple of 2.5 m, cut off the remaining part. Use brush the paint the cross section to ensure protection against corrosion and to provide aesthetic look for the ladder.

A.3.3 Connecting and Installing Cabling Troughs

Because cabling trough is cone-shaped, you can insert the smaller end of a cabling trough to the bigger end of another. The depth of inserted part is 250 mm. When 200mm-wide or 400mm-wide cabling trough is used, directly place the cabling trough on cabling ladder, and secure the cabling trough on the cabling ladder with fixing clips. For each segment of the cabling trough, four such clips are used and they should be symmetrical at both sides.

The connection of cabling troughs is shown in Figure A-23.

Cabling trough

Cabling troughfixing clip

Cabling ladder Protective ring

Figure A-23 Connection of cabling troughs (200 mm or 400 mm wide)

If a cabling trough is installed on 600mm-wide cabling ladder, it can be formed by means of joining a 200mm-wide trough and a 400mm-wide trough together with connecting clips. For each segment of cabling trough, three connecting clips are required. To install a cabling trough, secure it on cabling ladder with fixing clips. If a longer cabling trough is required, the connecting method is same as that mentioned earlier. Here, follow the principle “extended first and fixed next”.

The structure of 600 mm-wide trough is shown in Figure A-24.

A.3.4 Installing Turning Cabling Rack

I. Connecting Cabling Racks on a Horizontal Surface

When a cabling rack has to turn perpendicularly on a horizontal surface, there are two different installation ways with regard to whether the cabling trough is adopted or not.

Cabling trough is not adopted

If the crossed cabling racks consist of only cabling ladders, use angle connecting pieces and fasteners to joint the two cabling ladders. Make sure that the two cabling ladders are on the same horizontal surface as shown in Figure A-25.

(1) Angle connecting piece

Figure A-25 Cabling ladders turning on a horizontal surface

Cabling trough is adopted

When either or both of the crossed cabling racks have cabling troughs, there must be a height difference between the two cabling racks, that is, the height of the cabling ladder of one cabling rack must be the same as the height of the cabling trough of another cabling rack, to ensure that the cables shall not encounter any trouble while turning on the cabling rack. The installation is shown in Figure A-26. In the installation, angle connecting pieces and fasteners are also used, whereas the installation method of the angle connecting pieces is different from that in as shown in Figure A-25.

(1) Angle connecting piece

Figure A-26 Cabling rack with cabling trough turning on a horizontal surface



A-12

II. Connecting Cabling Racks not in Horizontal Surface

When you want to connect cabling ladders not in a horizontal surface, use a segment of cabling ladder to make a climbing ladder. Use angle connecting pieces and fasteners to connect the cabling ladder and climbing ladder.

Figure A-27 shows the vertical connection of cabling ladders, in which the left figure shows front view of the connection, and the right figure shows the side view of the connection. Pay attention to the installation of the angle connecting pieces shown in the figure.

III. Connecting Cabling Ladder onto Wall

When the cabling rack has to be connected to the wall, use the installation method as shown in Figure A-29. The connecting components include angle connecting piece,



A-13

insulating plate, insulating washer, fastener and expansion bolt. Insulating plate and insulating washer are used to ensure insulation between the cabling rack and the wall. Meanwhile, big flat washer (φ8 of GB96-85) is used to replace the washer for the expansion bolt to increase the contact area between the washer and the insulating washer

A.3.5 Installing Cabling Rack in Suspension Mounting Mode or Ground Supporting Mode

You can use suspension mounting mode or ground supporting mode when cabling rack is not placed against the wall. The suspension mounting mode is similar to the ground supporting mode, except that in the former installation mode, the cabling rack is connected to the ceiling, while in the latter the cabling rack is connected to the ground. The connecting components include channel-section steels, angle connecting pieces, fasteners and expansion bolts. To install a cabling rack in suspension mounting mode or ground supporting mode, use two pieces of channel-section steels to connect the cabling ladder to the ceiling or the ground. The installation method is the same as that of connecting cabling rack to the wall.



A-14

Each piece of channel-section steel is 2.5 m long. You can cut proper length according to the heights of the cabling rack and of the equipment room. If the required length is longer than 2.5 m, connect two pieces of channel-section steel by channel-section connecting piece with the same method as connecting cabling ladders. Meanwhile, paint the cut cross sections.

Because the spacing between the holes in the channel-section steel is 50 mm, the spacing between the suspenders or between the supporting levers must be an integral multiple of 50 mm. Otherwise, it is impossible to proceed with the installation. It is recommended that each segment of the cabling ladder is hung or supported by two sets of suspenders or supporting levers, and the spacing between two suspenders or between two supporting levers is 1250 mm .

When the suspension mounting mode or ground supporting mode is adopted, the suspenders or the supporting levers have to be installed at the outer side of the cabling ladder to facilitate the placement of cabling trough. Meanwhile, insulating plate and insulating washer must be used to ensure the insulation between the suspension components and the ceiling, or between the ground supporting components and the ground, as shown in Figure A-30.

A.3.6 Installing Triangular Support



A-15

Note:

The spacing between two triangular supports must be an integral multiple of 50 mm; otherwise, cabling ladders cannot be connected and fixed to triangular supports. A spacing of 1250 mm is recommended between two triangular supports, that is, each segment of cable ladder is supported by two triangular supports.

When cabling rack is placed against the wall, a triangular support is used to support the cabling rack. The triangular support adopts a welded structure, and it is fixed onto the wall by expansion bolts. It provides holes in its horizontal beam for installing cabling ladder. The triangular support has three specifications corresponding to the 200mm-wide, 400mm-wide, and 600mm-wide cabling ladders respectively. A larger triangular support can be used to support smaller cabling ladder, but it is not recommended here. The sizes of their installation holes in the wall are the same.

To install a triangular support, use expansion bolts to fix the support onto the wall. Use big flat washers (φ8 of GB96-85) to replace the flat washers of the expansion bolts. Meanwhile, install two insulating plates between the vertical beam of the triangular support and the wall, and install an insulating washer between the nut and the vertical beam.

To install cabling ladder onto the triangular support, place it directly on the horizontal beam of the triangular support. Align the holes on the lower side of the channel-section steel with the holes in the horizontal beam of the triangular support, and then fix them with fasteners, as shown in Figure A-31.

A.3.7 Installing Cabling Rack over Cabinet

I. Introduction to Installation Ways

Cabling rack can be installed over the cabinet in the following two ways (Generally, cable distribution trough is not configured on the top of cabinet for the purpose of improving system heat dissipation).

If shockproof support is installed on the cabinet, connect the cabling rack with the quake-proof support.

If no shockproof support is installed on the cabinet, connect the cabling rack with the cabinet by climbing ladder.

II. Connecting Cabling Rack with Shockproof Support

Shockproof support on the top of cabinet is welded with channel steel, and it can meet the strength requirements. It can be fixed to the two bolt holes on top of cabinet. There are bolt holes on the top plate of the shockproof support, used for fixing and bearing the cabling rack (cabling ladder).

The connection method is shown in Figure A-32 and Figure A-33.

Figure A-33 Connection of cabling rack and shockproof support

III. Connecting Cabling Rack with Climbing Ladder

If there is no support installed on the top of cabinet, use climbing ladder based on the size of the connecting holes provided on the top of cabinet. For specific connecting method for climbing ladder, refer to the right figure in Figure A-27 or Figure A-28.

A.3.8 Installing Accessories

I. Installing Cable-Through Clip

Cable-through clip can be divided into two types according to whether cabling rack has cabling trough or not. Figure A-34 illustrates the case when cabling trough is not configured on cabling rack, in which, upward cable-through clip is used. When cabling trough is configured on cabling rack, downward cable-through clip is used to ensure that the upper plane of cable-through clip stays on the same level with the uppermost plane of cabling rack, and to facilitate cabling. Generally, cable-through clip is installed on the cabling ladder on the top of cabinet, and the required quantity and location depend on actual conditions of the installation site.

Figure A-34 Installation of cable-through clip when cabling trough is not configured on cabling rack

II. Installing Baffle Rings

Baffle rings are directly snapped at both sides of a cabling trough. Configuring baffle rings can increase the height of a cabling trough to prevent cables from going beyond the cabling trough. Each segment of cabling trough uses four such rings and they are distributed evenly at both sides, as shown in Figure A-23.

III. Installing End Covers

End covers are installed at the ends of a cabling ladder. Wherever possible, end covers must be installed to provide better appearance and prevents unintended damage to cables.

IV. Installing Cable Bushings

Cable bushings are installed at the bottom edge of a cabling trough, used to prevent cables from any possible damage. Any uncovered bottom edge of cabling troughs must be installed with cable bushing.

The installation of end cover and cable bushing is shown in the left part of Figure A-27.

B.2.4 Printing Labels

I. Introduction to Label Printing

The contents can be printed or written on the labels. Printing is recommended for the sake of high efficiency and eye-pleasant layout.

II. Template for Printing

The Word-format template is available for label printout. You can download the template from http://tech-support.huawei.com/asp/comm/index.asp (path: //support/technical document/project management/installation and maintenance/document/others), or get the template from Huawei local office.

When using the template, you can directly modify the contents on the template, and the following must be observed:

The settings of centered characters, direction, and fonts must not be changed. When there are too many characters to be filled in, zoom out the characters, but

make sure the printouts are clear and legible.



B-4

III. Cells Merging on the template

To merge the cells, you need first recover the table structure (if gridlines are displayed, you can start from Step 3 directly).

1) Select the menu item [Edit/Select All]. 2) Select the menu item [Format/Borders and Shading/Borders]. Select Box and

click <OK>. 3) Drag the mouse to select the cells to be merged and select the menu item

[Table/Merge Cells].

If two merged cells are still not enough to accommodate the characters, use multiple lines.

IV. Requirements For the Printer

To print the labels, laser jet printer must be used, although there is no restriction on the model of the printer. Before printing the label, set up the page and try the printing on ordinary blank paper (both sides are blank):

1) Cover the blank paper onto the whole page of label paper, and check whether the page setup conforms to the requirement.

2) Make sure the printer properties, such as "paper size" and “direction”, have been set correctly.

3) If the warning prompt as shown in Figure B-3 appears before printing, click <Ignore> to continue the printing.

Figure B-3 Warning prompt before printing

If the printout confoms to the requiremnt, print it to label paper. If the printout does not conform, adjust the page setup and try the printing again, until the correct printout is produced. The method of adjusting the page setup is as follows:

1) Select the menu item [File/Page Setup]. 2) Select the Margins tab page. 3) Select Left for Gutter Position. 4) Set Header and Footer as 0, and adjust the values of Top, Bottom, Left, and

Right.

After the page setup has been made correct, save it for future use. This page setup is only necessary in the first time you use the template to print the labels.



B-5

V. Requirements for Feeding the Printer

Different from the ordinary paper, the label paper is composed of two pages. No matter what model of printer you are using, feed in the labels one after another by hand. Never use the auto-feed mode in order to avoid jamming the labels. Different models of printers may have different feeding modes, make sure to feed in the labels correctly.

VI. Requirements for Printed Labels

Make sure the printed labels satisfy the following requirements:

All the printouts must be on the label, and nothing must be printed on the bottom page of the label.

Contents in the cells must be aligned in the center. In a single-line printout, the dividing lines and the mark “TO” must not be covered by the printed characters.

When the cells are merged and the printouts are made in multiple lines, avoid covering the mark “TO” when printing the texts by using the space bar to move the printing contents to the next line.

B.2.5 Writing Labels

Use the black oiliness markers delivered together with the device to write the labels.

In special cases, black ball-pens are allowed, although not recommended. When writing with the ball-pen, take care not to leave the oil on the label, which may contaminate the label and blur the words..

Note:

The delivered marker has two nibs. Make sure to use the smaller nib to write on the labels.

For the sake of easy recognition and good looking, the font in handwriting must be close to the standard typeface as much as possible. Table B-1 shows the standard typeface.

B.2.6 Affixing Labels

I. Affixing Label to Signal Cable

After printing or writing the label, remove the label from the bottom page and affix it to the signal cable, or the identification plate of the power cable.

The steps to affix a label to a signal cable are shown in Figure B-5, Figure B-6 and Figure B-7. The finished labels must be on the right or top of the cables, according to different cabling methods. The left part of the figures shows the method to affix the label when the cable is laid vertically, while the right part of the figures shows the method to affix the label when the cable is laid horizontally.

The label is affixed 2 cm from the connector on the signal cable. In special cases, for example, to avoid cable bent or affecting other cables, other positions are allowed to affix the labels.

The steps to affix a label to a signal cable are as follows:

1) Stick the label to the proper position on the cable, fold the narrow part of the label according to the directions shown in Figure B-5.

II. Information for Signal Cables

The two sides of the label affixed on the signal cable carry information about the location of the ports connected to both ends of the cable, as shown in Figure B-9.

The information is given like this:

Area 1 contains the location information of local end of the cable. Area 2 (with the mark "TO:") contains the location information of the opposite end

of the cable. Area 3 has been folded up inside the label.

Area 3Area 1Area 2 TO:

Figure B-9 Printed parts on the label for signal cables

Seen from the cabling end of the equipment, the text part of the label is on the right side of the cable. The side with “TO:” that is facing outside carries the location information of the opposite end; and the other side carries the location information of the local end. Therefore, the information in Area 1 at one end is the same as the information in Area 2 at the other end of the cable, and vice versa. In other words, the local information at one end is called the opposite information at the other end.

B.2.8 Remarks

The following remarks are made for attentions.

When printing/writing and affixing labels, pay attention to keep the labels clean. Because the label paper is made of moistureproof and waterproof material,

ink-jet printers and ink pens are forbidden for printing and writing labels. Labels must be affixed with good order in alignment.



B-10

Cable ties must be bundled in the same position of power cables, with identification plates on the same side.

The positions of “up”, “down”, “right” or “left” are all based on the viewpoint of the engineering person who is working on the label.

B.3 Engineering Labels for External Cables of Alarm Box

The external cables of alarm box are connected with the first subscriber cabinet of each row (used for power distribution). Labels pasted on the first cabinet of each row indicate which equipment is using the access terminal. Labels are not needed on the equipment side unless there is special requirement. In this case, only Area 2 of the label is filled in.

Table B-2 shows the information on the labels of alarm box external cables.

Table B-2 Information on labels affixed to the external cables of alarm box

Content Meaning Example

MN

MN: serial number of the cabinet in the equipment room

M: The cabinet rows from front to back are numbered from A to Z.

N: The cabinet columns from left to right are numbered from 01 to 99.

For example, A01 indicates a cabinet at Row A, Column 01.

Note:

Generally, the above numbering method is enough to identify the position of a specific cabinet. If cabinets are installed in a back-to-back manner, the facing direction of the cabinet must be specified, the numbering method like MNO is used. Here, “O” means the direction of the cabinet, which can be “A” or “B”. On the cable labels described below, this numbering method is used, unless otherwise stated.

The label on the alarm cable carries simple information, and only part of the text area needs to be filled in. It is recommended to keep the whole length of the label instead of cutting out the blank area.

Figure B-10 shows a label on the alarm cable, on which “A01” indicates that the alarm cable is connected from the first cabinet to the cabinet at Row A, Column 01 in the equipment room.

B.8 Engineering Labels for Power Cables

B.8.1 Labels for DC Power Cables

I. Introduction to the Labels

The labels are affixed to the DC cables that provide power for the cabinets, and the protection grounding cables, including the -48V, PGND, and BGND cables. The labels for DC power cables are affixed to one side of the identification plates on cable ties.

II. Label Information Meanings

Table B-9 shows the information carried on the labels for the DC power cables:

Table B-9 Information on labels affixed to the DC power cables

Content Meaning

MN(BC)--48V1

MN(BC)--48V2

MN(BC)-BGND

MN(BC)-PGND

MN(BC): BC is written right under MN.

On the equipment cabinet side, only MN is used to identify the cabinet.

On the power cabinet side, MN identifies the row and column number of the power distribution equipment like the control cabinet and distribution cabinet, BC identifies the row and column number of the -48V connecter (if there is no row number or column number, or the connecter can be identified without them, BC can be omitted). BGND and PGND have no row and column number for identification.



B-21

The label only carries location information about the opposite equipment, the control cabinet or the distribution cabinet, while information of the local end is not necessary. Table B-9 lists the information of two -48V power supplies on the label. The information for other DC voltages (such as 24V, 60V) should be given in similar methods.

III. Label Example

Make sure that labels are affixed in correction direction. That is, after the cable ties are bundled onto the cable, the identification plates with the labels should face up, and the text on the labels in the same cabinet should be in the same direction, as shown in Figure B-17.

(1) (2)

TO: A01 -48V2 B08

TO: B03 -48V2

Figure B-17 Example of the labels on the DC power cable

In Figure B-17, (1) indicates the label on the equipment cabinet side, which carries the information about the position of the cable on the power distribution cabinet. (2) indicates the label on the distribution cabinet side, which carries the information about the position of the cable on the equipment cabinet side.

On the equipment cabinet side, the label marked “A01/B08--48V2” on the cable indicates that the cable is -48V2 DC supply, which is from the 8th connecter on the second row of -48V bus bar in the cabinet at Row A, and Column 1 in the equipment room.

On the distribution cabinet side, the label marked “B03--48V2” indicates that the cable is -48V2 DC supply, which is from the equipment cabinet at Row B, Column 03 in the equipment room.



B-22

Note:

In the power distribution cabinet (or the first power cabinet of a row in the transmission equipment room), every terminal on the -48V terminal block has a numeric identification, like “08” in “A01/B08--48V2” in the above example. PGND and BGND are copper bars, on which all the terminals are connected. In this case, it is only necessary to specify the row and column of the power distribution cabinet. For example, “A01-BGND” means that the power cable is a BGND cable that connects to the BGND copper bar of the power distribution cabinet at Row A, Column 01 in the equipment room.

B.8.2 Labels for AC Power Cables

I. Introduction to the Labels

The labels are affixed to the AC cables that provide power for the cabinets, and the protection grounding cables, including the POWER, PGND, and BGND cables. The 220V AC cables and related PGND and BGND cables are covered with insulating sheath, so the labels only need to contain the words of “AC" and the cabinet number. The labels for AC power cables are affixed to one side of the identification plates on cable ties.

II. Label Information Meanings

Table B-10 shows the information carried on the labels for the AC power cables.

Table B-10 Information on labels affixed to the AC power cables

C.3 Installation Preparations

C.3.1 Planning Grounding Points

To achieve lightning protection, the antenna system must be correctly grounded. Generally, there are two grounding points, namely outdoor grounding point and indoor grounding point.

The satellite signal receiving antenna is usually installed on the top of a building. The outdoor grounding point should be set near the entrance from which the feeder cable is led in, and you must ensure that the grounding point is reliable. For example, if there is a mobile base station antenna or other antenna installed on the roof of the building, the feeder cable of the antenna is grounded reliably near the entrance. If you are not sure whether the grounding point is reliable, or there is no grounding point outdoors, it is allowed that the cable is not grounded outdoors. Because the grounding cable of grounding clip is 1m long, the distance between the grounding point and the feeder cable should be as near as possible, and is no more than 1 m generally. For the ease of fixation, the grounding body should be a piece of metal in the shape of board or strip.



C-3

The indoor grounding point is the protection grounding bar, which may not be near with the UMG8900 cabinet, for the feeder cable can go to the protection grounding bar.

C.3.2 Planning Antenna Installation Positions

I. Antenna Visible Range

To ensure the amount of satellites that the antenna can receive, the antenna must be installed in a position with enough visible range, that is, the visible range must be over 50% of the whole sky.

II. Radio Frequency (RF) Interference

Because the GPS satellite signal is weak and vulnerable to the interference of other RF signals, the GPS antenna should be installed in a position where there is no high-power transmitter antenna. If there is no other choice, the antenna should be kept as far from the transmitter antenna as possible. In general, it should be kept 20 m away from the mobile base station antenna. If there is a microwave transmitter antenna, the GPS antenna should be installed at the back of it, with a distance of more than 5 m.

III. Lightning Protection

To achieve lightning protection, the antenna cannot be installed at the corner of the roof. There should be lightning arrester, icon tower or other building higher than the antenna nearby, and in addition, the visual range and RF interference should be also taken into account.

C.4.2 Fixing Antenna Support

I. Fixing Support Onto Low Wall

If there is low wall of more than 40 cm around the roof, the antenna support can be fixed onto the wall. However, the pedestal of the support should be removed first. Follow the steps below to fix the support onto the wall:



C-5

1) Lift the antenna pole and put it again the wall. Two U clips are needed for fixing the antenna pole onto the wall. Draw the positions for installing U clips. To ensure reliability and stability, two U-shape clips should keep a distance of no less than 40 cm, and their positions on the wall should be symmetrical.

2) Drill holes according to the marks on the wall. The expansion bolt M10 is used. 3) Fix the antenna pole with U-shape clips. To ensure stability, the washer is

needed. After the fixation, pull and spin the pole to check whether it is fixed tightly.

If there are two sets of antenna systems, they should be kept more than 2m away from each other. The antenna support fixed on the wall is as shown in Figure C-2.

1. Antenna pole 2. Lightning protection box 3. Low wall 4. Expansion bolt

Figure C-2 Schematic diagram of antenna support fixed onto the low wall

II. Fixing Support onto Cement Pedestal

If the antenna support is required to be fixed in the middle of the roof, a cement pedestal need be built first, which should be 500 mm long, 500 mm wide and 200 mm high. The cement pedestal should be strong enough and its surface should be level.



C-6

In addition, the impact of outdoor temperature should be taken into account when building the pedestal. Especially in cold area, the cement pedestal should be built in advance, for if the temperature is too low, the construction cannot be carried out on site. Generally, it is required that the cement pedestal is built in advance before installing the equipment. If there are two sets of antenna systems, their pedestals should be kept 2m away from each other.

Caution:

It is prohibited to directly drill holes on the roof to fix the support.

Follow the steps below to fix the support onto the cement pedestal:

1) Put the metal underpan of the antenna support onto the middle position of the pedestal, and then mark the positions of the installation holes.

2) Drill holes according to the marks with the D-12 mm drill. 3) Fasten the expansion bolts to fix the underpan. To ensure good receiving

capability of the antenna, keep the underpan as horizontal as possible. If not, add washers.

4) Insert the antenna pole into the underpan and ensure the pole is vertical, with the deviation less than 5 degree. Fasten the screws on the underpan to fix the antenna pole.

The antenna support fixed on the cement pedestal is as shown in Figure C-3.

Figure C-3 Schematic diagram of antenna support fixed onto the cement pedestal

C.4.3 Installing Antenna

The holder on the top of the support is used to fix the antenna. Place the antenna on the holder and insert the signal interface at the bottom of the antenna into the hole of the holder, then fix the antenna with four screws on the antenna support, as shown in Figure C-4 and Figure C-5.

C.4.4 Installing Lightning Arrester

I. Installing Outdoor Lightning Arrester

The outdoor lightning arrester leads the Inducting lightning current inducted on the feeder core to the cover of lightning arrester, which is connected to the shielding layer of feeder. Because the shielding layer is grounded through grounding clip before the feeder enters the building, it is not necessary to ground the outdoor lightning arrester separately. To install the outdoor lightening arrester in the lightening protection box on the antenna support, follow the procedure below:

1) Unscrew the screws on the lightning protection box and take off the cover. You can see the lightning arrester bracket.

2) There are two holes in the bracket, a bigger one and a smaller one. Insert the N connector at the “SURGE” end of the lightning arrester into the bigger hole, and insert the small screw of the N connector into the smaller hole. Then fix the N connector and the small screw with the accessory nuts and washers of the lightning arrester. See Figure C-6.

1. Lightning arrester 2. Lightning arrester bracket

Figure C-6 Schematic diagram of installing outdoor lightning arrester

II. Installing Indoor Lightning Arrester

The indoor lightning arrester leads the over-voltage that may inducted on the feeder core to the cover of lightning arrester. The indoor lightning arrester is not installed in the cabinet or other dedicated equipment, instead, it is usually placed on the cabling rack or under the ESD-preventive floor. The output end (that is, "PROTECTED" end) of the lightning arrester is connected to FCLK board by 3.5m feeder conversion cable. The small screw on the lightning arrester cover is the grounding end, which is



C-10

connected to the PGND of the cabinet or the grounding bar in equipment room by the grounding cable of the lightning arrester.

C.4.5 Making N Connector of 1/2" Super Flexible Feeder Cable

If the FSJ4-50B 1/2" super flexible feeder cable is used, the N connector will be made on site. In this case, the surplus feeder cable can be cut off. Refer to the instruction book delivered with the N connector to make it.

The required tools include hacksaw, knife, small file, brush, 19 mm spanner, 22 mm spanner, and electric dryer.

To make an N connector, follow the steps below:

1) To ensure quality, the cable for connecting the connector must be straight. 2) Cut the cable with a hacksaw to ensure the evenness of the cable section, as

shown in Figure C-7.

Figure C-7 Cable section

3) Strip the sheath of the cable for 28 mm long with a knife to expose the corrugated cooper tube. The sheath should be cut neatly, and be careful not to damage the copper pipe, as shown in Figure C-8.

Figure C-8 28 mm sheath stripped

4) Cut a 7 mm long corrugated cooper tube at the front end with the hacksaw, and then clear the foam with the knife to expose the core. Clean up the cut of the corrugated cooper tube with a file and brush. Be careful not to damage the core. See Figure C-9.



C-11

Figure C-9 Cutting 7 mm-long corrugated cooper tube to expose the core

5) Put the small rubber band around the corrugated cooper tube until it encloses the cable sheath, as shown in Figure C-10.

Figure C-10 Adding rubber band

6) Use the small file to rasp the section of the core into a slant face with width of 1mm, to facilitate connecting the N connector.

7) Smear a little lubricant on the small rubber band, and install the latter part of the N connector and then fasten it, as shown in Figure C-11.

Figure C-11 Lower part of N connector

8) Smear a little lubricant on the rubber band to install the front part of the N connector, and then fasten it by cooperation of two spanners. See Figure C-12.

II. Connecting and Laying Jumper

The 1.5 m jumper is used to connect the antenna and outdoor lightning arrester through N connector. To connect and lay jumper, follows the steps below:

1) For GPS antenna, N connector is used. Smear the front part of the N connector with a little silica gel, but keep the latter part clean, and then connect it with 1.5 m jumper.

2) For GPS/GLONASS antenna, TNC/N conversion connector should be used. Smear a little silica gel on the TNC/N conversion connector first, add the TNC/N conversion connector, then smear some silica gel on the TNC/N conversion connector, and then connect it with 1.5 m jumper.



C-14

3) After connecting the jumper, paste semiconductor adhesive tape on the connecting point for at least 8 cm long and 3 layers thick. Then use insulating tape to cover the semiconductor adhesive tape.

4) Connect the other end of the jumper to the "SURGE" end of the outdoor lightning arrester. The jumper out of the lightning protection box should be bent downwards, to prevent rain water from entering the box.

5) Use cable ties to bind the jumper onto the antenna support, but the first binding point should keep a distance of 20 cm from the antenna head, avoiding the antenna head from bearing weight. Bind the cable tightly and leave the cable ties towards the same direction. All the cable ties should be cut smoothly. The antenna support connected with the feeder cable is as shown in Figure C-15.

Figure C-15 Antenna support connected with feeder cable

III. Connecting and Laying Feeder Cable

The feeder is used to connect the “PROTECTED” end of outdoor lightning arrester and the “SURGE” end of indoor lightning arrester through N connector.

To connect and lay feeder cable, follow the steps below:



C-15

1) Connect the "PROTECTED" end of the outdoor lightning arrester to the feeder cable. At the connecting points, first use the semiconductor adhesive tape, then use the insulating tape to seal them.

2) Lay the feeder cable along the roof and wall/outdoor cabling ladder to the entrance of the building. When cabling by cabling ladder, the feeder cables should be bound with cable ties; when cabling by wall, the feeder cable clips should be used.

3) The feeder cable clip is as shown in Figure C-16. First, fix the L-shape bracket onto the wall with two M8 expansion bolts. Then clip the feeder cables with the U clip. Note to add rubber pads at the top and the bottom. Fasten the M5 screws.

1. L bracket 2. M5 screw 3. U-shape clip 4. Rubber pad

Figure C-16 Schematic diagram of feeder cable bracket

4) The feeder cables are bound with a feeder cable clip about every two meters. In case of cabling across the wall, to avoid damaging the feeder cables, use three clips respectively before crossing the wall, on the wall and after crossing the wall to prevent feeder cables from contacting the wall.

5) Before the feeder cable enters the building, if there is a reliable grounding point on the roof (for example, the grounding point used by the base station antenna), you need ground the shielding layer of the feeder cable with grounding clip as near as possible. Refer to Section C.4.7 Grounding Feeder with Grounding Clip for specific information about grounding procedure and attentions.



C-16

6) After the feeder cable is led indoors, it is led along the cabling ladder to the protection grounding bar in equipment room, keeping a distance of less than 1m from the protection grounding bar since the grounding cable of grounding clip is 1m long. Connect the shielding layer of the feeder cable to the PGND with the grounding clip. Refer to Section C.4.7 Grounding Feeder with Grounding Clip for specific information about grounding procedure and attentions.

7) In case of cabling indoors, the feeder cable is led along the cabling ladder or through the ESD-preventive floor. If the cabling ladder is adopted, the cables should be bound with cable ties.

8) Connect the feeder cable near the equipment side to the "SURGE" end of indoor lightning arrester.

9) Paste the labels as shown in Figure C-17 at both ends of the feeder cable. In the blank square, you need mark the feeder cable number, and then fold it oppositely. Make the side with words easy to see.

IV. Connecting and Laying Feeder Conversion Cable

The feeder conversion cable is used to connect the “PROTECTED” end of indoor lightning arrester and the ANT interface on FCLK board. Refer to Section 6.6.2 “Installing External Clock Cables” in Chapter 6 "Installing Signal Cables" of this manual for the specific connecting and cabling procedures.

C.4.7 Grounding Feeder with Grounding Clip

The grounding clip is used to ground the shield layer of feeder. The grounding cable of the grounding clip is 1m long, so ensure that the distance between the grounding point and the feeder cable is within 1m. If the grounding cable of the grounding clip is not long enough, extended cable of grounding clip can be used. However, it is not suggested to do so. By default, the yellow grounding cable with the length of 6m and the size area of 10 mm2 is delivered as the extended cable of grounding clip.

To ground feeder with grounding clip, follow the steps below:

1) Strip the sheath of the feeder cable for about 10 cm long. Be careful not to damage the shielding layer.

2) Roll the copper sheet of the grounding clip around the shielding layer for one circle, and then pull it out of the breach at the root. Clip the copper sheet with the



C-17

copper bar of the grounding clip, and spin the copper bar with straight screwdriver to tighten the cooper sheet, to make it well contacted with the shielding layer. However, do not tighten it too much, which may damage the feeder cable. At this time, the copper bar is wrapped inside the copper sheet. Do not take it out.

3) Use semiconductor adhesive tape to seal the connecting point for at least 20 cm long. It should be noted that no gap is allowed between grounding cable and the feeder cable. Then use insulating tap to cover the semiconductor adhesive tape completely. No part of the semiconductor adhesive tape should be exposed.

4) Fix the other end of the grounding cable onto the grounding body with bolt M8. Seal the connecting point with the semiconductor adhesive tape first and then the insulating tape. If the grounding cable of the grounding clip is not long enough, extension cable can be used. However, it is better not to use the extension cable. Seal the connecting point with the semiconductor adhesive tape first and then the insulating tape.

C.4.8 Requirements for Installing Antenna Feeder System

The requirements for installing antenna feeder system are as follows:

The connectors of the feeder cables must be tightened, to ensure its performance.

The connecting points should be sealed well with silica gel, semiconductor adhesive tape and insulating tape, especially at the connecting point between the antenna and the 1.5 m jumper.

Be careful when laying the feeder cable. Be sure to unroll the cable before laying it, avoiding damaging the cable due to inter-twist. The bending semi-diameter of the cable should be more than 15 cm.

If the connectors at both ends of the feeder cable have been made before the delivery, it is recommended not to cut the feeder cable on site, for the quality of the connectors cannot be ensured if they are re-made on site.

After the cables are connected to indoor lightning arrester, use the semiconductor adhesive tape and the insulating tape respectively to wrap the indoor lightning arrester and its connectors wholly. No metal should be exposed.

After the equipment is powered on, you can check the satellites that can be tracked. If more than four satellites can be tracked, it indicates that the antenna system functions normally.

The connection between the SSM and the UAM is shown in Figure D-1.

This figure illustrates the connection mode between the SSM and the rear access UAM through the example of the SSM connecting with the PV8 main frame by the E32 board. The PV8 board connects with the E32 board through eight E1 cables. The dashed line in the diagram above represents a logical line. A logical line means the two ends connect with each other through the transmission equipment or the DDF instead of connecting directly.

The two E1 cables of the PV8 main frame must be configured to different E32 boards in order to avoid the loss of communication between the UAM and the SSM due to the E32 board default.

E.10 Requirements for Power Supply

E.10.1 Requirements for AC Power Supply

I. Generic requirements on AC power supply

Adopt the centralized AC power supply model of mains, uninterrupted power supply (UPS), and a reserved diesel generator.

Ensure simplicity in cable connection, security in operation, flexibility in scheduling, and convenience in maintenance.

Adopt three-phase and five-wire, or monophase three-wire AC power for low-voltage power supply system.

Table E-7 lists the nominal voltage and rated frequency of low-voltage power supply system.

Table E-7 Specifications of AC voltage and frequency

Nominal voltage Rate frequency

110/127//220/380 V 50 Hz

Adopt UPS for the backup AC power supply. Keep it the same phase with mains. Set the switching time between mains and UPS less than 10 ms; otherwise, the product will reboot or reset itself.

Ensure that the equipment runs well below nominal current; never in the threshold of failure.

Use a separate AC power supply protection unit for a piece of separate equipment. The current to trigger the protection should be greater than the

When designing the DC power supply system, consider the maximum static and dynamic load of the system. Always keep sufficient room for the two thresholds.

Choose the model of the power cables by the maximum load of power supply.

The diesel generator set of the office automatically functions in case of power failure, automatically supply when the mains is insufficient, and automatically stops functioning when power restores. It can be tested and controlled remotely in standard interface and communication protocols.

II. Power supply specifications of AC-powered equipment

Here are the power supply specifications of AC-powered equipment:




E-10

Voltage fluctuation of communications equipment: –10% – +5% of rated voltage.

Voltage fluctuation of power supply equipment and important buildings:–15% – +10% of rated voltage.

Frequency fluctuation:–4% – +4%. Aberration rate of voltage sine wave: ≤5%.

III. Specifications of power cables

Here are the specifications of the power cables:

Use the neutral line of the same cross-sectional area as the live line. Select the DC power feeder on long-term load. Use fire-resistant AC cables.

Suggestions on AC power supply are as fllows:

When the voltage of mains power supply is not stable, use the voltage regulator in any of the following conditions:

Powered by mains, the voltage fluctuation of communications equipment exceeds the rated threshold (–10% – +5% of rated voltage).

Powered by mains, the voltage exceeds the rated voltage fluctuation of communications equipment.

Not directly powered by mains, the voltage fluctuation exceeds the rated threshold (–15% – +10% of rated voltage).

The voltage exceeds the rated AC voltage fluctuation of DC power supply equipment.

Use UPS or inverter to prevent interruption or surge of power supply. Use a diesel generator set when the mains is faulty. The capacity of the

generator set should 1.5 to 2 times of the capacity of UPS. Use two groups of storage batteries in parallel. Use one group of UPS storage batteries. The batteries can be working in

parallel or serial connection. Use main inverter based on the maximum power. Keep a backup one.

E.10.2 Requirements for DC Power Supply

Ensure stable power supply. Close the power supply equipment to the communications equipment to minimize the feeder line. The voltage level between battery and the equipment should be less than 3.2 V.

When there are more than two switching systems, use two or multiple independent power supply systems.

Set up multiple independent power supply systems for important communication centers, each of which powers a separate equipment room. For ordinary offices,




E-11

adopt the model of a centralized power supply room plus a battery room. For small-capacity offices, adopt the centralized power supply model. Always prevent the boards from the erosive chemicals given out from batteries.

Table E-8 specifies the requirements on DC power supply.

Table E-8 DC power supply specifications

Item Specifications

Voltage fluctuation of –48-V input end

–40V–57V

Anti-surge current capability

Should be 1.5 times greater than the rated load current capability.

Voltage stability When the AC input voltage range is from 85% to 110% of the rated value, and the load current is from 5% to 100% of the rated value, the output voltage of the current stabilizer is an integral value between –56.4 and –46.0V. The variance is less than equal to 1%.

Voltage surge at power-on and power-off

Less than equal to the integral value of DC output value ±5%

Peek-to-peek noise voltage

≤200mV

Dynamic response The recovery time is less than 200 ms. The exceeding amount should not be more or less than 5% of the rated DC output voltage.

Suggestions on DC power supply are as follows:

Use the distributed power supply model. Scatter the power supply systems to multiple sites.

Adopt standard DC power supply system. The output voltage of the power supply equipment should meet the requirement of the communications equipment.

Enhance the reliability of the power supply system. Optimize the capacity of the storage batteries. In small-capacity offices, when it is difficult to maintain the reliability of the power supply system, expand the capacity of the storage batteries.

The total configuration of high-frequency switch rectifier should meet the load power of communication and the recharging power of the storage batteries. Adopt the redundant configuration model for the rectifier module. Use a standby rectifier for less than ten active ones; and add one rectifier for every additional ten active ones.




E-12

Equip the storage batteries in two or multiple groups. The total capacity is determined by the power feeding duration. Ensure at least one hour of power supply capability for the storage battery group.
