NOTE: The FCM slot must not be empty for more than 2 minutes while the enclosure is powered.
Installing an FCM
You can hotswap the replacement of a single FCM; however, if replacing multiple FCMs, the enclosure must be powered off using an
orderly shutdown using the management interfaces.
1. Orient the FCM for insertion into the target slot on the enclosure rear panel, as shown in
2. Slide the FCM into the slot until the latch clicks home.
The enclosure should automatically detect and make use of the new module.
3. Wait for the Module OK LED on the newly inserted FCM to illuminate green. See
• If the Module OK LED does not illuminate, verify that the FCM is properly inserted and seated in the slot.
• If properly seated, the module may be defective. Check the ME Storage Manager and the event logs for more information.
• Using the management interfaces (the ME Storage Manager or CLI), determine if the health of the new FCM is OK. Verify that
the Module OK LED is green, and that the Ops panel states show no amber module faults.
4. If replacing multiple FCMs, repeat steps 1 through 4.

Replacing a power cooling module (PCM)

This section provides procedures for replacing a failed power cooling module (PCM). Illustrations in PCM replacement procedures show
rear panel views of the enclosure, with the PCM properly oriented for insertion into the rear panel of the enclosure.
A single PCM is sufficient to maintain operation of the enclosure. You need not halt operations and completely power-off the enclosure
when replacing only one PCM; however, a complete orderly shutdown is required if replacing both units simultaneously.
CAUTION: Do not remove the cover from the PCM due to danger from electric shock inside. Return the PCM to your
supplier for repair.
