1. Open the air duct and locate the NVDIMM battery.
2. Locate the battery plug and squeeze the clip on the face of the battery plug to release the plug from the
socket, and then unplug the battery cable from the socket.
3. Grasp the battery and press the blue locking tab marked PUSH, and then lift the battery out of the holder
and controller module.
4. Remove the replacement battery from its package.
5. Align the battery module with the opening for the battery, and then gently push the battery into slot until it
locks into place.
6. Plug the battery plug back into the controller module, and then close the air duct.
Step 4: Install the controller module
After you have replaced the component in the controller module, you must re-install the
controller module into the chassis, and then boot it to Maintenance mode.
1. If you have not already done so, close the air duct at the rear of the controller module and reinstall the
cover over the PCIe cards.
2. Align the end of the controller module with the opening in the chassis, and then gently push the controller
module halfway into the system.
Do not completely insert the controller module in the chassis until instructed to do so.
3. Cable the management and console ports only, so that you can access the system to perform the tasks in
the following sections.
You will connect the rest of the cables to the controller module later in this procedure.
4. Complete the reinstallation of the controller module:
a. Make sure the latch arms are locked in the extended position.
b. Using the latch arms, push the controller module into the chassis bay until it stops.
c. Press down and hold the orange tabs on top of the latching mechanism.
d. Gently push the controller module into the chassis bay until it is flush with the edges of the chassis.
The latching mechanism arms slide into the chassis.
The controller module begins to boot as soon as it is fully seated in the chassis.
