5Obtaining the ESN
The Electronic Serial Number (ESN) is a unique identifier of a Network Element (NE). Record
the ESN for later commissioning of the base station before installation.
Procedure
Step 1 Record the ESN on the BBU.
l If there is not a label on the FAN unit of the BBU, you must record the ESN and site
information that is printed on a mounting ear of the BBU. Figure 5-1 shows the position of
the ESN.
l If there is a label on the FAN unit of the BBU, the ESN is printed on the label and a mounting
ear of the BBU. In this case, you must take the label and record the site information on the
side labeled Site, as shown in Figure 5-2.

Figure 8-1 Marking anchor points
(1) Wall (2) Front (3) Left
Step 2 Drill holes at the anchor points and install the expansion bolt assemblies.
1. Use a hammer drill with bit 16 to drill holes at the marked anchor points. Ensure that the
depth of each hole ranges from 52 mm to 60 mm, as shown in Figure 8-2.
Use a vacuum cleaner to clear the dust inside and around the holes. If the inter-hole spacing
is too wide or too narrow, locate and drill holes again.

15.1 Cabling Requirements
Route cables according to the specified cabling requirements to prevent signal interference.
NOTE
If a cable listed below is not required, skip the routing of the cable.
General Cabling Requirements
The bending radius of the cables must meet the following specifications:
l The bending radius of the 7/8'' feeder must be more than 250 mm (9.84 in.), and the bending
radius of the 5/4'' feeder must be more than 380 mm (14.96 in.).
l The bending radius of the 1/4'' jumper must be more than 35 mm (1.38 in.). The bending
radius of the super-flexible 1/2'' jumper must be more than 50 mm (1.97 in.), and the bending
radius of the ordinary 1/2'' jumper must be more than 127 mm (5 in.).
l The bending radius of the power cable or PGND cable must be at least five times the
diameter of the cable.
l The bending radius of the optical fiber must be at least 20 times the diameter of the optical
fiber.
l The bending radius of the E1/T1 cable must be at least five times the diameter of the cable.
l The bending radius of the signal cable must be at least five times the diameter of the cable.
The cables must be bound as follows:
l Different types of cables must be separately routed and cannot be entangled.
l The cables must be bound tightly and neatly. The sheaths of the cables must not be damaged.
l The cable ties must face the same direction, and those at the same horizontal line must be
in a straight line. Extra length of cable ties must be cut.
l Labels or nameplates must be attached to the cables after they are installed.
The cables must be routed as follows:
l Different types of cables must be separately routed with a minimum space of 30 mm (1.18
in.) between every two cables.
l Different types of cables must be installed in an untangled and orderly fashion.
l Different types of cables must be routed in parallel or separated by special objects.
Special Cabling Requirements
Cabling requirements for power cables are as follows:
l -48 V DC power cables must be bound together.
l +24 V DC power cables must be bound together.
l Power cables, transmission cables, and signal cables are routed separately.
l Multiple power cables must be bound when routed.
l Power cables must be installed in the position specified in engineering design documents.
l If the length of power cables is insufficient, replace the cables rather than adding connectors
or soldering joints to lengthen the cables.
DBS3900(ICR)
15-3

Cabling requirements for PGND cables are as follows:
l PGND cables for the base station must be connected to the same ground bar.
l PGND cables must be buried in the ground or routed indoors. They should not be routed
overhead before they are led into the equipment room.
l The exterior of the coaxial wire and the shield layer of the shielded cable must have proper
electrical contact with the metal surface of the equipment to which they are connected.
l PGND cables and signal cables must be installed in an untangled and orderly fashion. A
certain distance must be reserved between them to prevent interference from each other.
l Fuses or switches must not be installed on the PGND cables.
l Other devices must not be used for electrical connections of the PGND cables.
l All the metal parts in the housing of the equipment must be reliably connected to the ground
terminal.
Cabling requirements for E1 cables are as follows:
l E1 cables must not cross power cables, PGND cables, or RF cables when routed. If
transmission cables are routed with power cables, PGND cables, or RF cables in parallel,
the spacing between them must be greater than 30 mm (1.18 in.).
l E1 cables are routed straightly and bound neatly with cable ties.
l Sufficient slack is provided in E1 cables at turns.
Cabling requirements for optical fibers are as follows:
l Do not stretch, step on, or place heavy objects on optical fibers. Keep the fibers away from
sharp objects.
l When optical fibers are routed, the extra length of the fibers must be coiled around special
devices, such as a fiber coiler.
l When coiling optical fibers, apply even strength. Do not bend the fibers with force.
l Vacant optical connectors must be covered with dustproof caps.

15.11 Installing the CPRI Optical Cable
This section describes the procedure for installing the CPRI optical cable.
Context
l The single-mode optical module is labeled "SM" and multi-mode optical module is labeled
"MM".
l If the puller of an optical module is blue, the module is a single-mode optical module. If
the puller of an optical module is black or grey, the module is a multi-mode optical module.
l The optical module to be installed must have a matching rate with the corresponding CPRI
port.
Procedure
l Installing the CPRI optical cable for the DC RRU
1. Wear an ESD wrist strap or a pair of ESD gloves.
2. Turn the puller of each optical module outwards, insert the optical module into the
CPRI port on the BBU and the CPRI_W or CPRI0 port on the RRU respectively,
and then turn the puller inwards, as shown in Figure 15-35.
Figure 15-35 Installing the optical module
3. Connect one end of the CPRI optical cable to the CPRI_W port on the RRU.
4. Connect the other end to the CPRI port on the BBU.
5. Route the optical cable in the cable trough by referring to Figure 15-36.
CAUTION
l When routing optical cables, coil the cables and place them on the top center of
the upper-level IMB03 to ensure that the holes for heat dissipation are not covered.
l The minimum bending radius of the fiber is 140 mm. When coiling the optical
cable, do not bend it excessively.

Installation Guide
Issue 01 (2011-03-30)

Context
CAUTION
l Fix a DIN connector near the cable rack before fixing another DIN connector far from the
cable rack when installing the antenna jumper for the DC RRU. Pre-bend the RF jumper
before connecting it to the RRU.
l The three wire clips in the middle of the cable trough are used for routing feeders. Each wire
clip holds four feeders. You must install the feeders on the lower level before installing the
feeders on the upper level.
l The minimum bending radius of the antenna jumper is 100 mm.
l When the STMA or Smart Bias-Tee (SBT) is used and the coaxial cable is used for the RET
antenna of the RRU3201, OOK signals are required. In this case, the ANT_TX/RXA port is
used for communications of the RET antenna.
Procedure
l Installing the antenna jumper for the DC RRU
1. Connect one end of the antenna jumper to the ANT_TX/RXA and ANT_RXB ports
at the bottom of the RRU.
2. Connect the other end to the feeder or antenna, as shown in Figure 15-40.
TIP
Pre-bend the feeder before tightening the feeder connector.

15.13 Installing a GPS Clock Signal Cable
This section describes the procedure for installing the GPS clock signal cable.
Procedure
Step 1 Connect the other end of the GPS clock signal cable to the GPS port on the USCU, orLMPT
NOTE
The GPS clock signal cable is connected to the GPS port on the USCU for a base station working in GSM
Only, UMTS Only, or GSM+UMTS mode. It is connected to the GPS port on the LMPT for a base station
working in LTE Only, UMTS+LTE, or GSM+LTE mode.
The route for the GPS clock signal cable is the same when the cable is connected to theLMPT, or USCU.
