Installing a PSU
If replacing both PSUs, the enclosure must be powered off via an orderly shutdown using the management interfaces.
1. Make sure that the PSU is switched off.
2. Orient the PSU for insertion into the target slot on the enclosure rear panel, as shown in Removing a PSU (2 of 2) on page
67.
3. Slide the PSU into the slot until the latch clicks home.
4. Connect the AC power cord.
5. Move the PSU power switch to the On position.
6. Wait for the Power OK LED on the newly inserted PSU to illuminate green. See Power supply unit (PSU) on page 19.
● If the Power OK LED does not illuminate, verify that the PSU 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 PSU is OK. Verify
that the Power OK LED is green, and that the Ops panel states show no amber module faults.
7. If replacing both PSUs, repeat steps 1 through 6.
Replacing a fan cooling module (FCM) in a 5U enclosure
This section provides procedures for removing and installing an FCM in a 5U enclosure.
The images in the FCM removal and installation procedures show rear panel views of the 5U enclosure.
Before you begin any procedure, see ESD precautions on page 42.
Removing an FCM
You can change all fan cooling modules as long as they are removed and inserted one at a time. We recommend that you shut
down the unit before removing two or more fans.
CAUTION:
Removing an FCM significantly disrupts the enclosure’s airflow. Do not remove the FCM until you
have received the replacement module. It is important that all slots are filled when the enclosure is in operation.
1. Identify the fan cooling (FCM) module to be removed. If the FCM module has failed, the Fan Fault LED will illuminate amber.
See Fan cooling module (FCM) on page 19.
2. Push the release latch down and hold it in place (detail No.1).
3. With your other hand, grasp the handle and pull the FCM outward (detail No.2).

4. While supporting the FCM with both hands, remove it from the enclosure.
