Controller module cover
Thumbscrew
2. Insert the controller module into the chassis
a. Ensure the latching mechanism arms are locked in the fully extended position.
b. Using both hands, align and gently slide the controller module into the latching mechanism arms until it
stops.
c. Place your index fingers through the finger holes from the inside of the latching mechanism.
d. Press your thumbs down on the orange tabs on top of the latching mechanism and gently push the
controller module over the stop.
e. Release your thumbs from the top of the latching mechanisms and continue pushing until the latching
mechanisms snap into place.
The controller module begins to boot as soon as it is fully seated in the chassis. Be prepared to
interrupt the boot process.
The controller module should be fully inserted and flush with the edges of the chassis.
3. Recable the system, as needed.
4. Return the controller to normal operation by giving back its storage:
storage failover giveback
-ofnode
impaired_node_name
5. If automatic giveback was disabled, reenable it:
storage failover modify -node local -auto
-giveback true
Step 5: Return the failed part to NetApp
Return the failed part to NetApp, as described in the RMA instructions shipped with the kit. See the
Replace the NVMEM battery - FAS500f
To replace an NVMEM battery in the system, you must remove the controller module from
the system, open it, replace the battery, and close and replace the controller module.
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.
