Replace a Fiber Cable from FBS to MPO Coupler Panel

This procedure describes how to replace fiber cables from the FBS to the MPO coupler panel.

1. Follow safety and ESD precautions.

   See Safety and ESD Precautions.

2. Remove FBS cover at the location of the failed cable.

   See Replace an FBS PCB for FBS cover removal instructions.

3. Using the label sheet, label the new cable.

7. When you have the replacement cable bundle up to the FBS at slot 34, install the remaining FBS covers.
8. Remove the MPO coupler panel.

   See Remove the MPO Coupler Panel.

9. Disconnect the faulty cable bundle from the MPO coupler panel.
