Tools Needed:
#3 Phillips screwdriver - recommended magnetic with 6" minimum shaft.  A 12-16" works best on this system.

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

1. Follow safety and ESD precautions.

2. From the front of the modular system:
a. Remove the status LED panel located on the top front of the modular system.
b. Disconnect the existing cable from the LED panel.
c. Connect the new cable to the LED panel, then route the cable to the rear of the modular system and over the coupler panel at slot 41.

3. Install the LED panel.

4. At the rear of the modular system:
a. Remove the node rear support bracket from slot 20.
b. Starting from the top, remove the FBS covers a few at a time.

Note:  You may find that disconnecting the right side of the FBS covers should be enough to feed the cable down from the top.

c. Lay the new cable in the right-side channel.  For any cable slack, lay it on top of the top most switch.
d. If possible, remove the faulty cable completely.

Note:  To facilitate easy removal of the bad cable, cut the ends off.

e. Disconnect the DB-9 cable from the FMM.
f. Connect the new DB-9 cable to the FMM.

5. Install the node rear support bracket at slot 20.
