Step 2: Remove the controller module
You must remove the controller module from the chassis when you replace the controller
module or replace a component inside the controller module.
1. If you are not already grounded, properly ground yourself.
2. Unplug the controller module power supplies from the source.
3. Release the power cable retainers, and then unplug the cables from the power supplies.
4. Loosen the hook and loop strap binding the cables to the cable management device, and then unplug the
system cables and SFP and QSFP modules (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.
5. Remove the cable management device from the controller module and set it aside.
6. Press down on both of the locking latches, and then rotate both latches downward at the same time.
The controller module moves slightly out of the chassis.
