Replace the controller module hardware - AFF A220 and FAS2700
To replace the controller module hardware, you must remove the impaired controller,
move FRU components to the replacement controller module, install the replacement
controller module in the chassis, and then boot the system to Maintenance mode.
Step 1: Remove controller module
To replace the controller module, you must first remove the old controller module from the chassis.
1. If you are not already grounded, properly ground yourself.
2. Loosen the hook and loop strap binding the cables to the cable management device, and then unplug the
system cables and SFPs (if needed) from the controller module, keeping track of where the cables were
connected.
Leave the cables in the cable management device so that when you reinstall the cable management
device, the cables are organized.
3. Remove and set aside the cable management devices from the left and right sides of the controller module.
4. If you left the SFP modules in the system after removing the cables, move them to the new controller
module.
5. Squeeze the latch on the cam handle until it releases, open the cam handle fully to release the controller
module from the midplane, and then, using two hands, pull the controller module out of the chassis.
