NetApp AFF A900 - Replacing the real-time clock battery; Shut down the impaired node

5. Make sure that the on/off switch of the new power supply is in the Off position.
6. Using both hands, support and align the edges of the power supply with the opening in the system chassis,
and then gently push the power supply into the chassis until it locks into place.
The power supplies are keyed and can only be installed one way.
Do not use excessive force when sliding the power supply into the system. You can damage
the connector.
7. 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.
8. Turn on the power to the new power supply, and then verify the operation of the power supply activity
LEDs.
The green power LED lights when the PSU is fully inserted into the chassis and the amber attention LED
flashes initially, but turns off after a few moments.
9. After you replace the part, you can return the failed part to NetApp, as described in the RMA instructions
shipped with the kit. Contact technical support at
NetApp Support, 888-463-8277 (North America), 00-800-
44-638277 (Europe), or +800-800-80-800 (Asia/Pacific) if you need the RMA number or additional help
with the replacement procedure.
Replacing the real-time clock battery - AFF A900
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 node
You can shut down or take over the impaired controller using different procedures,
depending on the storage system hardware configuration.
Option 1: Most configurations
To shut down the impaired node, you must determine the status of the node and, if
necessary, take over the node so that the healthy node continues to serve data from the
impaired node storage.
About this task
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
node shows false for eligibility and health, you must correct the issue before shutting down the impaired node;
see the
Administration overview with the CLI.
