Ensure the FAN is in the bottom when installing the BBU.

1. Install the PGND cable ofOMB cabinet.

The procedures for installing the cables as follows in

the DC OMB and in the AC OMB are the same: PGND cable E1/T1 cable or FE/GE ethernet cable

optical cable

If the cable connection scenarios are similar, the

description is based on the DC cabinet.

1. Insert the optical module into the CPRI0, CPRI1,

CPRI2, CPRI3, CPRI4 or CPRI5 port.

3. Remove the dustproof caps from the

optical connectors.

4. Insert the optical connector at one end of the CPRI optical cable into the optical module.

Lead the CPRI optical cable out of the cabinet along the left side of the cabinet.

The shielded straight-through cable

must be used as the FE/GE Ethernet

cable.

Insert the DLC connectors labeled 2A and 2B at one end of the CPRI optical cable into the

optical module on the GTMU, and then insert the DLC connectors labeled 1A and 1B at

the other end into the optical module on the RRU.

If both ends of the optical cable are the LC

connectors, the TX and RX ports on the BBU

are respectively connected to the TX and RX

ports on the RRU.

The single-mode optical module is labeled "SM"

and multi-mode optical module is labeled "MM.

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.

BBU Hardware Installation Checklist

SN Item

1 All self-made PGND cables are copper-based with the proper wire diameters. No breaking device such as switch

and fuse is allowed for the electric connection of the grounding system. No short circuit is allowed. Each terminal

on the ground bar 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 than coiled.

3 The terminals at both ends of the power cable or PGND cable are securely soldered or crimped.

4 The bare wires and the terminal handles at the wiring terminals are coated with heat-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 cable connections at the bottom of the

cabinet.

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

8 The power cable, PGND cable, feeder, optical cable and the E1/T1/FE/GE signal cable are bound separately

with a spacing of larger than 3 cm.

9 The cable layout facilitates maintenance and future capacity expansion, and the bending 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 smooth without sharp edges. An extra

length of 3 mm to 5 mm is reserved for each outdoor cable tie.

12 The idle connectors of the cables are properly protected.

Remove the GTMU and UELP from the BBU.

Setting the DIP Switchesa

Wear an ESD wrist strap during the operations on theboards to prevent damage to the boards.

The UELP is optional. Please check the settings of the DIP switches according to the field conditions.

Obtaining the ESN

Record the Electronic Serial Number (ESN) shown on the label attached tothe mount ing ear of the BBU, and report the ESN to the engineer for thecommissioning of the base station.
