4. Grasp the battery and press the blue locking tab marked PUSH, and then lift the battery out of the holder

Step 4: Reinstall the controller
After you replace a component within the controller module, you must reinstall the
controller module in the system chassis and boot it to a state where you can run
diagnostic tests on the replaced component.
1. If you are not already grounded, properly ground yourself.
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. Recable the system, as needed.
If you removed the media converters (QSFPs or SFPs), remember to reinstall them if you are using fiber
optic cables.
4. Complete the reinstallation of the controller module:
The controller module begins to boot as soon as it is fully seated in the chassis. Be prepared to interrupt
the boot process.
a. With the cam handle in the open position, firmly push the controller module in until it meets the
midplane and is fully seated, and then close the cam handle to the locked position.
Do not use excessive force when sliding the controller module into the chassis to avoid
damaging the connectors.
b. Tighten the thumbscrew on the cam handle on back of the controller module.
c. If you have not already done so, reinstall the cable management device.
d. Bind the cables to the cable management device with the hook and loop strap.
e.
As each controller starts the booting, press
Ctrl-C to interrupt the boot process when you see the
message Press Ctrl-C for Boot Menu.
