optic cable, and insert the connector into the optical module on the BBU.
2. Route the fiber optic cable out of the cable outlet on the bottom right side of the cabinet.

Step 3 Lay out the cables according to the instructions in Cabling Requirements. If a fiber optic patch
cord is used as a BBU interconnection signal cable, use binding straps to bind the BBU
interconnection signal cable before using cable ties to secure it. If another type of cable is used
as a BBU interconnection signal cable, directly use cable ties to secure it.
Step 4 Label the installed cables according to the instructions in Attaching an L-Shaped Label.
