Tools Needed:

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

1. Remove FBS cover at the slot where the faulty cable is located.

2. Disconnect the faulty cable.

3. Connect the replacement cable.

Note: In the steps below, you will be instructed to replace the FBS covers. They are easy to install incorrectly.
When installed correctly, the top back edge of the cover will be underneath the FBS, it should not be lying on top of it. You can look at RU 18 or 34 for reference or you can remove and install the one at RU 34 to see how it should be installed.

4. Remove the nearby FBS covers, and start laying in the replacement cable, reinstalling FBS covers as you install the cable toward the FMM.

5. When the cable is at the FBS before the FMM (slot 18 or 21), install the remaining FBS covers.

6. Remove the cosmetic covers from slots 19 and 20.

7. Remove the front and rear node support brackets at slot 20. Note the orientation, the shelf is on top.

8. If necessary, remove the cosmetic cover mounts to plug in the replacement cable.

9. Disconnect the faulty cable from the FMM.

10. Coil up the excess replacement cable.

11. Connect the cable to the FMM port vacated by the faulty cable.

12. Reinstall the node support brackets (slot 20).

13. Reinstall the cosmetic cover mount (if removed), and the cosmetic covers.
