Figure 61. Removing an FCM (2 of 2)
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 Removing an FCM (2 of 2) on page
69.
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 Fan cooling module (FCM) on page 19.
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 PowerVault Manager and the event logs for more
information.
Using the management interfaces (the PowerVault 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) in a 2U enclosure
This section provides procedures for removing and installing a PCM in a 2U enclosure.
The images in the PCM removal and installation procedures show rear panel views of the 2U 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.
Before you begin any of the procedures, see the ESD precautions on page 42.
NOTE:
The figures show PCM module replacement within the right slot as you view the enclosure rear panel. To replace a
PCM in the left slot, rotate the module 180º so that it properly aligns with its connectors on the back of the midplane.
Removing a PCM
CAUTION:
Removing a power supply unit significantly disrupts the enclosures airflow. Do not remove the PCM
until you have received the replacement module. It is important that all slots are filled when the enclosure is in
operation.
