Installing the BBU Cables
The procedures for installing the cables as follows in the DC OMB and in the AC OMB are the same: z PGND cable z E1/T1 cable or FE/GE ethernet cable z optical cable If the cable connection scenarios are similar, the description is based on the DC cabinet.
1. Install the PGND cable of OMB cabinet.

8. Install the CPRI optical 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. 1. Insert the optical module into the CPRI0, CPRI1, CPRI2, CPRI3, CPRI4 or CPRI5 port. 2. Turn outwards the puller on the optical module.
Optical module
Puller
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.
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.
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.

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.
Powering On the BBU
47
Obtaining the ESN Record the Electronic Serial Number (ESN) shown on the label attached to the mounting ear of the BBU, and report the ESN to the engineer for the commissioning of the base station.

Appendix a Setting the DIP Switches Remove the GTMU and UELP from the BBU.
Wear an ESD wrist strap during the operations on the boards to prevent damage to the boards.
The UELP is optional. Please check the settings of the DIP switches according to the field conditions.
