Replace controller module - AFF A300
To replace the controller module hardware, you must remove the impaired node, 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: Open the 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. Loosen the thumbscrew on the cam handle on the controller module.
