To replace the AC module:
1. Remove the replacement AC module from its protective
anti-static bag.

module for bent or broken connector pins that may have been
damaged during shipping. If any pins are damaged, obtain a new
assembly.

power LED on the front bezel, green LED on the active CTP card,
and green PWR OK LEDs on both power supplies remain lit. If a
problem is indicated, go to
Chapter 3, Maintenance analysis
procedures (MAPS) to isolate the problem.

— If at the management server, open the Hardware View and
observe the AC module graphics to ensure no alert symbols
appear that indicate a failure (yellow triangle or red diamond).
If a problem is indicated, go to
Chapter 3, Maintenance analysis
procedures (MAPS) to isolate the problem.
— If at a web browser connected to the EFCM Basic Edition
interface, open the Switch tab at the View panel and ensure no
amber LEDs illuminate that indicate FRU failure. If a problem
is indicated, go to
Chapter 3, Maintenance analysis procedures
(MAPS) to isolate the problem.
