5. Using both hands, support and align the edges of the power supply with the opening in the controller
module, and then gently push the power supply 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
power supply into the system.
6. Reconnect the power supply cabling:
a. Reconnect the power cable to the power supply and the power source.
b. Secure the power cable to the power supply using the power cable retainer.
Once power is restored to the power supply, the status LED should be green.
7. Return the failed part to NetApp, as described in the RMA instructions shipped with the kit. See the
page for further information.
Replace the real-time clock battery
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” section of the
ONTAP 9 NetApp Encryption Power Guide
.
ONTAP 9 NetApp Encryption Power Guide
• If you have a SAN system, you must have checked event messages (
event log show
) for impaired
controller SCSI blade.
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.
• If you have a cluster with more than two nodes, it must be in quorum. If the cluster is not in quorum or a
healthy controller shows false for eligibility and health, you must correct the issue before shutting down the
impaired controller; see the
Administration overview with the CLI
.
• If you have a MetroCluster configuration, you must have confirmed that the MetroCluster Configuration
State is configured and that the nodes are in an enabled and normal state (
metrocluster node show
).
