2. Install the CPRI optical cable.
The TX port on the BBU is connected to the RX port on the RRU.
The RX port on the BBU is connected to the TX port on the RRU.
Connect the OT terminal of the power cable to the LOAD3
terminal of the PDU, and then fix the 3V3 connector of the
power cable to the PWR port on the BBU.
1. Install BBU power cable.
The OT terminals of the power cable is to be made on site.
Optical module
Puller
a. Insert the optical module into the CPRI0,
CPRI1, CPRI2 CPRI3, CPRI4 or
CPRI5 port, and then turn outwards
the puller on the optical module.
b. Insert one end of the CPRI optical cable
into the optical module, and then lead
the CPRI optical cable out of the
cabinet along the right side of the
cabinet.
c. Wrap the fiber tail with the winding pipe.

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.
Connect the fiber tails labeled 2A and 2B to one of the CPRI0 to CPRI5 ports on the
GTMU, and connect the fiber tails labeled 1A and 1B to the CPRI_W port on the RRU.

corner of the cabinet to expose the shielding layer
4.4. Thread the E1/T1 cable through the grounding clip. Then, tighten the screw on the
grounding clip to make the shielding layer of the E1/T1 cable in full contact with the
grounding clip. Finally, connect the PGND cable on the grounding clip to the ground bolt
of the APM30.
