Installing a Power Cable
NOTE
Here is the process of installing a BBU power
cable in the TP48200A cabinet. For details about
how to install a BBU power cable in other
scenarios, please see "Installing a BBU Power
Cable" in eNodeB Product Documentation.
1. Connect the 3V3 connector at one end of
the BBU power cable to the -48 V port on the
UPEU module of the BBU, and tighten the
screws on the connector to 0.25 N· m.
2. Connect the other end of the BBU power
cable to the TP48200A cabinet.
a) Connect the cord end terminal to the
BLVD 16 A MCB port F6.
b) Connect the OT terminal of the BBU
power cable to the positive busbar of the
TP48200A.

c1 Installing an FE/GE Optical Fiber
1. Lower the puller of an optical module and
insert the optical module into the SFP0/SFP1
port on the LMPT, the FE/GE1 port on the
UMPTb2, or the XGE1/XGE3 port on the
UMPTe3. Then, raise the puller.
3. Bind the cables properly using the optical fiber
binding strap based on BBU cable claw positions.
4. Install the winding pipe at the end of the
optical fiber. Ensure that the winding pipe is
installed at the position between the optical fiber
connector and the first optical fiber binding point.
2. Remove the dustproof cap from the optical
fiber. Connect an FE/GE optical fiber to the
optical module.
