Step 3: Remove the controller module
To replace the chassis, you must remove the controller module or modules from the old
chassis.
1. 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.
2. Remove and set aside the cable management devices from the left and right sides of the controller module.
3. Loosen the thumbscrew on the cam handle on the controller module.

4. Pull the cam handle downward and begin to slide the controller module out of the chassis.
Make sure that you support the bottom of the controller module as you slide it out of the chassis.
5. Set the controller module aside in a safe place, and repeat these steps if you have another controller
module in the chassis.
