Step 2: Remove controller module
To access components inside the controller, you must first remove the controller module from the system and
then remove the cover on the controller module.
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.
