2.1 Addressing Requirements for Equipment RoomZXWR RNC should be installed indoors. To ensure ZXWR RNC running stably for along time, locate ZXWR RNC in the equipment room according to the telecommunicationnetwork planning and communication technical requirements, as well as the hydrology,geological, traffic. The followings are detailed requirements:

l Do not place the equipment in the room with high temperature, thick dust, harmfulatmosphere, low air pressure, flammable and explosive objects.

l Do not place the equipment in the room with shakes.l Do not place the equipment in the room with large noises.l Do not place the equipment in the room near the transformer substation.

2.2 Construction Requirements for Equipment Room

2.2.1 LayoutUsually, the equipment room falls into the main equipment room and the auxiliaryequipment room. The main equipment room is to locate the body device of ZXWR RNC,while the auxiliary equipment room is to locate the auxiliary devices, such as, O&Mdevice, uninterrupted power supply, and battery set.

The followings are detailed requirements:

2-1



l To ensure the running environment of the equipment is independent, easy to maintainand manage, the main equipment room and the auxiliary equipment room should beplaced separately. However, they should be placed near the equipment, to save thecables for the next installation.

l Place the O&M console in the auxiliary equipment room and ensure that the O&Mpersonnel can face the equipment in the main equipment room.

l Usually, the main equipment room and the assistant room are separated with glasswalls.

l Do not place the main device and the primary power supply in the same room.

2.2.2 SizeThe equipment room should be large enough to support the main body and assistantdevices of ZXWR RNC, loading materials and other devices. Usually, keep 1.5 m beforethe ZXWR RNC cabinet for the maintenance person to open the door.

The layout of the equipment room is as shown in Figure 2-1.

Figure 2-1 LAYOUT OF EQUIPMENT ROOM

2.2.3 HeightThe height of the equipment room is related to the cablingmode selected during the systemdesign.

The system cabling has 2 modes: Upward cabling and downward cabling:

l Upward cabling: All connection cables are wiring on the top of the cabinet.l Downward cabling: All connection cables are led out from the cabinet bottom.

2-2


Chapter 2 Environment Requirements

The equipment room height refers to the net height from the beam or ventilation pipe tothe floor surface. Usually, for the upward cabling mode, the equipment room height shouldnot be less than 3 m, while for the downward cabling mode, the equipment room heightshould not be less than 2.7 m.

2.2.4 FloorsThe floors should be laid in the equipment room according to the following requirements:

l The bearing weight capacity of the floors in the main equipment room should be over560 kg/m2 and the bearing weight capacity of the auxiliary equipment room should beover 300 kg/m2.

l The pavement and the support of the floors must be smooth and firm. The error forper m2should be less than 2 mm.

l Coat the floor with the anti-static floors. Do perform the antistatic grounding. Thegrounding method is to connect a well-conductive lead with the grounding device ofthe equipment room via 1 M current-limiting resistance.

The grounded system resistance should comply with YD/T754-95 TelecommunicationEquipment Room Static protection Regulations (issued in June, 1995).

l The floors are better to be 300 mm ~ 330 mm high. Avoid flaring designs.l The paint should be non-glisten and harmless.l When laying the floors, take measures against moisture, moth and rats.

If the equipment room adopts the downward cabling mode, reserve the hidden pipes,grounding trough, and holes under the floors. Their quantity, location and sizes shouldmeet the requirements for the layout of different cables and the technical design. Takemoisture-proof measures for all troughs. Keep the edge smooth. All the illumination andpower cables should be laid hidden.

2.2.5 Windows/Doors/Wallsl Door: The effective height is over 2 m and the width over 1 m.l Window: Conditions permitting, all doors and windows use double-deck glass, sealed

with dustproof rubber bars. Clear the dusts regularly.l Wall: Use the paints or wallpapers against the absorption, fire and moisture. Or, use

the non-luminous paint.l Ceiling: No leaking and no dusting.

2.3 Temperature/Humidity Requirements for EquipmentRoom

The temperature/humidity requirements for the working environment of ZXWR RNC arelisted in Table 2-1.

2-3



Table 2-1 TEMPERATURE/HUMIDITY REQUIREMENTS

Name Long-term Working Condition Short-termWorking Condition

Temperature 0C ~ 40C -5C ~ 45C

Humidity 20% ~ 90% 5% ~ 95%

Note:

The temperature/humidity is measured when there are no protection boards in front of orbehind the cabinet, 1.5 m above the floors, 0.4 m before the equipment.

Short-term working duration means no more than 48 hours continuously, and no more than15 days accumulated in the whole year.

To guarantee the working environment and the temperature/humidity can meet the aboverequirements, the main equipment room should be equipped with the air-conditionerthat is constantly ON, and the auxiliary equipment rooms should also be equipped withthe air-conditioner that runs seasonally as required (based on the climate and financialconditions of the operator). Generally speaking, large equipment rooms should beequipped with the air-conditioners with humidity regulation, while small equipment roomswith general floor-standing or window air-conditioners.

l Validation

The capacity of the air-conditioner validating system includes the heat of the mainequipment and the heat of the external devices (such as, the heat brought by thesunlight entering the room through the windows and walls, the heat brought by themaintenance personnel coming into/out of or staying in the room).

The air-conditioner should be double backed up to ensure the validating systemrunning securely and reliably. Especially in the main equipment room, the capacityof each system should be larger than at least half of the total air-conditioner capacity.

l Sealing

Do not destroy the sealing of the equipment room because of installing theair-conditioner. The property of the fresh air entering the equipment room should beover 5%.

In addition, keep the air clean. Not only the density and the diameter of thedust, but also the salt, acid and sulfur in the air, should comply with CF014-95Telecommunication Equipment Room Condition (Temporary). These harmful gasesmay speed up the corruption of the metal and the aging of some parts. Preventharmful gases, such as, SO2, H2S from entering the equipment room, avoidingharming the health of the missionary.

2-4



2.4 Illumination Requirements for Equipment RoomIt is better to install incandescent lamps or fluorescent lamps that are embedded into theceiling at proper positions between cabinets (or install emergency illuminating devices),for the convenience of equipment installation and maintenance. The average illuminationis 300 ~ 450 Lx.

Lamp light or sun light should not irradiate the equipment for a long period, to prevent circuitboards and components from aging and deforming due to high temperature. Therefore, itis better to use the colored glass and non-tint transparent curtain for windows.

2.5 Power Supply Requirements for Equipment RoomAC/DC/UPS of the equipment room should meet the following requirements:

1. DC

a. The nominal voltage of power supply for the equipment room is -48V, with anallowed fluctuation range of 57 VDC ~ -40 VDC.

b. Threshold values measured at DC distributor output terminal, of the noise levelindices that 48 VDC voltages involves, are:l 300 Hz ~ 3400 Hz (phone band) noise (weighted noise) voltage 2 mVl 0 Hz ~ 300 Hz peak-peak value noise voltage 400 mVl 3.4 kHz ~ 15 kHz broadband noise voltage 100 mV effective valuel 150 kHz ~ 30 MHz broadband noise voltage 30 mV effective value.

Discrete frequency (single frequency) noise voltage:

l 3.4 kHz ~ 15 kHz, 5 mV effective valuel 150 kHz ~ 200 kHz, 3mV effective valuel 200 kHz ~ 500 kHz, 2mV effective valuel 500 kHz ~ 30 MHz, 1mV effective value.

c. DC power supply is secured with over-voltage/over-current protection andindicators.

2-5



l Harmonic distortion < 5%l Output waveform: Sine wavel Working mode: Online workl Dynamic response time < 2ms

2.6 Grounding Requirements for Equipment RoomMost faults of the equipment result from improper grounding. Especially in the case oflightning, improper grounding will cause even worse damage. Therefore, it is essentialto check the equipment room grounding and the grounding conditions that the equipmentroom provides to the equipment.

2.6.1 Grounding System CompositionsA complete grounding system is as shown in Figure 2-2.

Figure 2-2 COMPLETE GROUNDING SYSTEM

The grounding system consists of the grounding body, grounding in-lead cable, groundingcable and grounding busbar.

l Grounding body: The conductor buried underneath the ground and in contact with theearth.

l Grounding busbar: The public grounding busbar that leads grounding cables out ofthe equipment room and the power supply room.

l Grounding in-lead cable: The connection cable between the grounding busbar andthe grounding body.

2-6



l Grounding cable: The connection cable between the communication device and thegrounding busbar.

2.6.2 Grounding System TypeCommon grounding system includes the lightening protection ground, working ground andprotection ground.

l Lightning protection ground: The lightning protection system of the constructionfacilities, consisting of the lightning arrester, the down grounding conductor, andconnectors that connect with the grounding system.

l Working ground: The common potential reference formed by the connectedcomponent loop inside the equipment.

l Protection ground: The ground that is led from the protection end or the outerenclosure of the equipment. It is to prevent the metal outer enclosure of theequipment from bearing electricity caused by power supply faults or other reasonsof the equipment.

2.6.3 Grounding System DesignThe equipment room is better to adopt joint grounding mode.

Joint grounding is to connect the working ground, protection ground of the equipment, andthe lightning ground of the building to form one set of grounding body. It can be severalground grids (for example, equipment room ground grid, power room ground grid, and irontower ground grid).

Joint grounding can prevent ground level breakdown effect. Ground level breakdowneffect: If the lightning strikes a building with electronic communication equipment,the electromagnetic induction will increase the level of the electronic communicationequipment. If the grounding body of the equipment is separate from the grounding bodyof the building, the level of the equipment is zero, a huge potential occurs between thecircuits and components of the equipment and the ground. In this case, the componentsand the circuits are very likely to break down.

In the case of joint grounding mode, if the lightning strikes a building with electroniccommunication equipment, the electromagnetic induction will increase both the levelof the circuits of the electronic communication equipment and the ground level. In thiscase, there will not be a sharp potential between the components and the circuits of theequipment and the ground. They are not likely to be damaged.

2.6.4 Grounding System RequirementsThe resistance for the equipment room in joint grounding mode should be below 1 .

ZXWR RNC ground includes -48 V ground, working ground, and protection ground.

l -48 V ground (-48 V GND) and working ground (GVD) are led out from the powerdistribution box, connecting with GND and -48 VGND of all subsystems via the busbar.

2-7



l Protection ground (GNDP) connects with the cabinet via the busbar, connecting withDC grounding stake via the cabinet.

l The cabinet provides up grounding mode and down grounding mode.l The resistance of cabinet bonding connection is 0.1 ~ 0.3 . The grounding resist-

ance of the equipment room is less than 1 .l The system does not provide analog grounding. The analog grounding on the board

joins the digital ground at the power supply.

2.7 Fire Protection Requirements for Equipment RoomThe main building of the equipment room must meet GBJ16-87 Building Design FireProtection Specifications or the corresponding requirements of native standards. Equipthe corresponding fire equipment and reserve sufficient fire passages. Put notice boardsbearing Key Fire Protection Site at proper locations.

Do not store such hazardous articles as flammable or explosive articles in the main orauxiliary equipment room. Stick No Smoking orNo Smoke and No Fire signs wherenecessary. The fire control water should be enough to guarantee 2 hours supply. Leadthe water pipes across the equipment rooms and do not set the fire hydrant indoors.

Install the alarming devices for smog and high temperature and inspect frequently toguarantee their good performance.

2.8 Lightening Protection Requirements for EquipmentRoom

When the height of the main building or its auxiliary facilities (such as the chimney,antenna and water tower) exceeds 15 m, take measures compliant to the lightning-proofrequirements for Class-II civil buildings and structures. In the lightning protection design,take measures against direct-strike lightning and the lightning current incursion.

In addition, take measures against side strike when the equipment room is in a high-risebuilding. For example, connect the outer metal windows of the building with the lightningprotection down lead; install horizontal lightning-protection metal straps on the outersurface of the wall at certain intervals along the height of the building.

Take the following lightning protection measures for the main building of the equipmentroom:

l Install lightning protection nets or lightning protection straps on the parts of the buildingthat are subject to lightning.

l Equip protruding objects, such as chimney, antenna and water tower, with overheadlightning conductor or arrestor.

l The cross section area of the leadwire of the lightning protection device is not less than200 mm2, with a distance not greater than 30 m. The impulse grounding resistanceof the lightning protection grounding device for the building is not greater than 10 .

2-8



l Ground outdoor cables andmetal pipes before they enter the building. Fix the lightningarrestors where outdoor overhead cables enter the equipment room.

l Employ the metal components of the building itself (such as reinforcing steel barsinside walls or poles) as the down leads for lightning protection grounding. Connectthese down leads electrically to equalize the inside electric potential.

l Install proper lightning protection devices for the power supply system along the mainsinput line to the equipment room.

2.9 Radiation Protection Requirements for EquipmentRoom

The equipment room should be far away from high-power radio transmitting station, radartransmitting station, and high-frequency large-current equipment. The actual electric fieldintensity radiated to the equipment room should be below 300 mV/m, and the intensity ofmagnetic field should be less than 11 Gs.

Generally, take the following anti-radiation measures:

l Shield the equipment room or shield against the definite electromagnetic radiationinterference source.

l Install a shielding wall between the principal equipment of the system and theequipment containing a transmitter with high-frequency radiation, and using separatepower supply lines.

l The power line and the conductive line in the pipe should be grounded reasonablyand the shield layer of all the cables should be grounded.

l Intertwine the signal lines and return lines so that the conductive voltage caused bythe line radiation interference offsets itself.

l The power cable and the signal line had better be routed separately.l Strictly separate AC grounding cable and DC grounding cable in the equipment room.

2.10 Anti-static Requirements for Equipment Room

Note:

Before operating on the device sensitive to the static, read related precautions carefullyand stick the anti-static labels on both front sides of rack.

Electrostatic will damage the components in a repeated way. The damage will beaccumulated, which causes intermittent performance problem or performance reduction.Electrostatic will also cause software failure, malfunction or misoperation of the electricswitches and control circuits.

2-9



Electrostatic induction comes from external electric fields like high-voltage line andlightning, and from internal systems like interior environment, floorboard, and systemstructure. O&M personnel can also cause ESD from the body by touching the equipment.

The following measures can effectively eliminate the harm caused by electrostaticdischarge:

l Ground the equipment properly Ground the equipment at several points with copperfoils (apply and press copper foils between the concrete floor and the semi-conductivefloor, and connect the copper foils with a ground cable).

l Lay anti-static floors and ground them. The resistance of the anti-static raised floorshould comply with Technical Requirements on Raised Floor Boards in ComputerRoom. If the raised floor is unavailable, pave the conductive floorboards (the volumeresistance should be 1.0 107 W ~ 1.0 1010 W). The static-conductive or raisedfloor must be grounded, connected to the grounding device via the current-limitingresistor and cables. The value of the current-limiting resistance is 1 MW.

l O&M personnel should wear ESD wrist strap for operation, and connect ESD strapwith the electric static discharge hole on the equipment cabinet.

2.11 Dustproof Requirements for Equipment RoomIn the equipment room, it is necessary to limit the density of the dust, the diameter greaterthan 5 m and the density less than 3 104 particles/m3. Make sure the dust particlesnot electric-conductive, magnetic-inductive or corrosive. Take the following dust-proofmeasures:

l Seal the doors and windows. Install the double-layered glasses on the outer windowand seal. Add dust-proof draught excluder strips on the doors. Preferably, the skylightcan seal the equipment room, equipped with a dust filter.

l Keep the uniforms and slippers clean and change them at a proper frequency.l Place the operating equipment in the outer room, to avoid opening/closing of the door

of the equipment room too often.l Keep the relative humidity in the equipment room at a proper high level as allowed, to

mitigate dust adherence caused by electrostatic.l Coat the walls and ceilings of the equipment room with paint or wallpaper, preferably

with lusterless paint.

2.12 Quakeproof Requirements for Equipment RoomTake quakeproof measures on the equipment (especially when the equipment room hasa raised floor) according to the designed intensity of the local quake. The quakeprooffacilities should be available in the equipment room to make the equipment room strongenough against a Richter scale-7 earthquake.

5.4.5 Testing Insulation for Feet Installation Mode

Context

The insulation test is required for the cabinet feet once one cabinet foot is fixed.

Steps

1. Set the multimeter to the resistor mode.

2. Measure the resistance by connecting the two instrument probes to the metal part ofthe cabinet feet and the expansion bolt respectively.

If the circuit disconnects, this foot passes the insulation test. Otherwise, the foot is notinsulated with the ground. In this case, check whether the insulating tube is installedor whether the insulating tube is damaged.

Note:

Perform the insulation test every time fixing one foot. Otherwise, the workload is heavyafter the insulation test is found unqualified at a latter stage of the installation.

5.6 Cabinet Accessories InstallationAccessories are required to be installed after the cabinet installation completes.

Cabinet accessories include cable trough, decorative panel, fan plug-in box, fiber tray,front/rear door, air filter and label.

5.6.1 Cable Trough InstallationThe requirements for cable trough installation are as follows:

1. The installation positions of the cabling ducts and troughs should comply with thespecifications given in the construction design chart.

2. The horizontal ducts should be parallel to the cabinet row or intersected with it in aright angle.

3. The vertical duct should be strictly vertical to the ground.4. The hanging brackets of the ducts should be neatly and firmly installed. Keep them

strictly vertical without tilting.5. Install the sub-cover for protection where the cabling duct passes the floor hole or the

wall hole. After laying and binding the cables, seal the holes with the cover plates.Both the sub-cover and the cover plates are made from fireproof materials.

6. When installing the unilateral or bilateral cabling ducts along the wall, the supports onthe wall should be firm and reliable, evenly spaced in the horizontal direction. Theducts should be neat in line and in order.

7. The cable troughs and ducts should be straight, firm and vertical to the major row. Thetroughs between cabinet rows should be in line without any dust inside. The troughsfor high-current cables and those for weak-current cables should be completelyseparated. To put high-current cables in the trough for the weak-current cables,proper shielding measures should be taken.
