Note
Required Tools and Equipment
•
ESD-preventive wrist strap
•
Number-1 Phillips magnetic screwdriver
•
Replacement PCM (Cisco PID NC6-PCM=)
Steps
Step 1
Attach the ESD-preventive wrist strap to your wrist and connect its leash to the ESD jack on the front side of the FCC
(see
Preventing Electrostatic Discharge, on page 11
). You can also connect the wrist strap to any bare metal surface on
the FCC.
Step 2
Power off each set of power trays by using turning the I/O power switch to OFF on the respective PCM.
Step 3
Completely power off the entire system at the supply circuit breakers.
Step 4
Remove the four M4 Phillips pan-head screws from each power tray. Using the ejector handles, slide the power tray
forward just enough to disengage the connector to the PCM without removing the power cables (approximately 1-inch).
The power trays must be pushed out so that the PCM freely disengages from the connector.
Note
Step 5
Using the magnetic screwdriver, remove the screws from the PCM (
).
a) Loosen and remove the two 6-32 pan-head screws on the left front face of the PCM.
