WARNINGTake proper safety measures to protect your eyes and respiratory tract against the dustbefore drilling holes.

2. Use a vacuum cleaner to clear the dust inside and around the holes. If the inter-hole spacingis too wide or too narrow, locate and drill holes again.

3. Slightly tighten the expansion bolt, and then put the expansion bolt assembly into the holevertically.

4. Use a rubber mallet to hammer the expansion bolt until the expansion tube is buried intothe hole.

5. Remove the M12x60 bolt, spring washer, and flat washer from each expansion boltassembly in sequence.

WARNINGAfter disassembling the expansion bolt assembly, ensure that the top of the expansion tubeis on the same level as the floor.

Step 3 Install the base and adjust the base level.1. Place the insulating spacer and the base on the floor, align the mounting holes in the base

and in the insulating spacers with the holes of the expansion bolts in the floor, and then usefour M12x60 bolts to secure the base, as shown in Figure 7-3.

ContextFigure 7-6 shows the support for installing the ESD floor.

Figure 7-6 Support for installing the ESD floor

(1) Access holes (2) Frames (3) Mounting hole

The support for installing the ESD floor on which the BTS3900 is installed is classified into twotypes: support with fixed height and support with adjustable height. Table 7-1 lists the relationsbetween the two types of supports and the height of the ESD floor.

Table 7-1 Height of the support for installing the ESD floor

Type of the Support Height of the ESD Floor (Unit: mm)

Support with fixed height 296 to 495

Support with adjustableheight

120 at least; adjustable according to the height of the floor

NOTE

Height of the ESD floor refers to the spacing between the concrete floor and the upper surface of the ESDfloor.

Procedure

Step 1 Determine the installation position of the cabinet on the ESD floor by referring to Installing theCabinet on the Concrete Floor Step 1.

Step 2 Drill holes on the ESD floor.1. Use a percussion drill with bit 16 to drill holes at the anchor points. The holes should

penetrate the ESD floor, as shown in Figure 7-7.

Figure 7-7 Drilling a hole on the ESD floor

WARNINGTake proper safety measures to protect your eyes and respiratory tract against the dustbefore drilling holes.

2. Use a vacuum cleaner to clear the dust inside and around the holes. If the inter-hole spacingis too wide or too narrow, locate and drill holes again.

Step 3 Position the support.1. Place the support under the ESD floor, and then use bolts to secure the ESD floor on the

support temporarily, as shown in Figure 7-8.

Cabling requirements for PGND cables are as follows:

10 Installing the CablesBTS3900

Installation Guide


Issue 03 (2010-05-04)

l The PGND cables for the base station must be connected to the same ground bar.

l The PGND cables must be buried in the ground or routed indoors. They should not berouted overhead before they are led into the equipment room.

l The exterior of the coaxial wire and shielding layer of the shielded cable must have properelectrical contact with the metal surface of the connected equipment.

l The PGND cable and signal cable cannot be bound or entangled. A certain distance mustbe reserved between them to prevent interference from each other.

l Fuses or switches cannot be installed on the PGND cables.

10.6 Installing the RF JumperThe RF jumper connects the RFU to the antenna system for signal exchange between the basestation and the antenna system.

Procedure

Step 1 Lead the RF jumpers into the cabinet through the cable holes, and the route the jumpers byreferring to 10.2 Cable Routing Principles.

NOTE

Reserve an extra length of 300 mm when preparing the RF jumper according to the actual cable route. Thus, thejumper can be led out from the upper cabinet if two cabinets are stacked during capacity expansion. For detailsabout how to add a DIN connector to the RF jumper, see Assembling the 7/16 Straight Male Coaxial DINConnector and the 1/2'' Feeder.

Step 2 Link the DIN connectors of the RF jumpers to the ports labeled ANT on the panels of the RFUs.Figure 10-16 shows the RF jumper connections in a single cabinet, and Figure 10-17 showsthe RF jumper connections in stacked cabinets.

Step 3 Use a torque wrench to tighten the DIN connector until the fastening torque reaches 25 N·m to35 N·m.

Step 4 Attach color rings by referring to Color Ring for the Antenna System and Attaching the ColorRing.

NOTE

Check and ensure the secure connections of the Inter-RFU RF signal cables, which are installed inside thecabinets based on different configurations of the cabinets before delivery.

10.7 Installing the Monitoring Signal Cable for the EMUThe monitoring signal cable for the EMU transmits monitoring signals from the EMU to theBBU3900.

Procedure

Step 1 Insert the RJ-45 connector at one end of the monitoring signal cable for the EMU into the portlabeled MON1 on the UPEU in the BBU3900.

Step 2 Link the DB9 male connector at the other end of the monitoring signal cable for the EMU to theport labeled RS485 on the EMU, and then tighten the screws.

11 Installation Checklist

After the cabinets and devices are all installed, you need to check the installation items,installation environment, and cable-related items.

Checking the Cabinet Installation

Table 11-1 describes the cabinet installation checklist.

Table 11-1 Cabinet installation checklist

1 The base is securely installed.

2 All the bolts, especially those for electrical connections, are tightened. Both thespring washer and the flat washer are installed in a correct sequence.

3 The surface of the cabinet is neat and clean.

4 The cabinet meets the dustfree requirement.

5 The paint on the surface is satisfactory. The damaged paint is repaired.

6 All labels, tags, and nameplates are correct, legible, and complete.

Installation Environment Checklist

Table 11-2 describes the installation environment checklist.

Table 11-2 Installation environment checklist

1 No redundant tapes or cable ties are left on the cables.

2 No tapes, tails of cable ties, paper, or packing bags are left inside or outside thecabinet.

3 All the items around the cabinet are neat, clean, and intact.

Electric Connection ChecklistTable 11-3 describes the electric connection checklist of the cabinet.

Table 11-3 Electric connection checklist of the cabinet

1 All self-made PGND cables are copper-based with the proper wire diameters. Nobreaking device such as switch and fuse is allowed for the electric connection ofthe grounding system. No short circuit is allowed. Each terminal on the groundingbar can be connected with only one wiring terminal of the PGND cable.

2 The redundant part of the power cable or PGND cable is stripped off rather thancoiled.

3 The lugs at both ends of the power cable or PGND cable are securely soldered orcrimped.

4 The bare wires and the terminal handles at the wiring terminals are coated withheat-shrinkable tubes.

5 The flat washer and the spring washer are well mounted on all OT terminals.

6 All cables are connected securely and reliably. Pay special attention to the cableconnections at the bottom of the cabinet.

7 The cables are neatly and tightly bound. The cable ties are evenly spaced and facethe same direction.

8 The power cable, PGND cable, feeder, optical cable and the E1/T1/FE signal cableare bound separately with a spacing of larger than 30 mm.

9 The cable layout facilitates maintenance and future capacity expansion. And thebending radius of the cables meet the requirements.

10 All the labels at both ends of the cables are legible.

11 The extra length of each indoor cable tie is cut, and the cut surface is smoothwithout sharp edges. An extra length of 3 mm to 5 mm is resereved for eachoutdoor cable tie.

12 The idle connectors of the cables are properly protected.

13 The connectors of the RF cables are fixed in position to avoid false connectionthat may cause an abnormal voltage standing wave ratio (VSWR).

13 Obtaining the ESN

The Electronic Serial Number (ESN) is unique to a Network Element (NE) for identification.The ESN is used during the commissioning of the base station.

Procedure

Step 1 Record the ESN shown on the label attached to the mounting ear of the BBU. Figure 13-1 showsthe position of the ESN.

Figure 13-1 Obtaining the ESN

Step 2 Report the ESN to the engineer for the commissioning of the base station.

Step 3 Close the cabinet door, and lock it.
