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.

Remove and set aside the cable management devices from the left and right sides of the
controller module.
4.
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
