5. Install the replacement PSU in the controller module:
a. Using both hands, support and align the edges of the replacement PSU with the opening in the
controller module.
b. Gently push the PSU into the controller module until the locking tab clicks into place.
The power supplies will only properly engage with the internal connector and lock in place one
way.
To avoid damaging the internal connector, do not use excessive force when sliding
the PSU into the system.
6. Reconnect the D-SUB DC power cable:
a. Plug the power cable connector into the PSU.
b. Secure the power cable to the PSU with the thumbscrews.
Once power is restored to the PSU, the status LED should be green.

Part Return & Replacements page for further information.
Replace the real-time clock battery - AFF A800
You replace the real-time clock (RTC) battery in the controller module so that your
system’s services and applications that depend on accurate time synchronization
continue to function.
• You can use this procedure with all versions of ONTAP supported by your system
• All other components in the system must be functioning properly; if not, you must contact technical support.
Step 1: Shut down the impaired controller
To shut down the impaired controller, you must determine the status of the controller and, if necessary, take
over the controller so that the healthy controller continues to serve data from the impaired controller storage.
About this task
• If you are using NetApp Storage Encryption, you must have reset the MSID using the instructions in the
Returning SEDs to unprotected mode.
•
If you have a SAN system, you must have checked event messages (
cluster kernel-service show)
for impaired controller SCSI blade. The
cluster kernel-service show command displays the node
name, quorum status of that node, availability status of that node, and operational status of that node.
Each SCSI-blade process should be in quorum with the other nodes in the cluster. Any issues must be
resolved before you proceed with the replacement.
