Removing the controller modules

To replace the chassis, you must remove the controller modules from the old chassis.

Steps

  1. If you are not already grounded, properly ground yourself.
  2. Release the power cable retainers, and then unplug the cables from the power supplies.
  3. 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.
  4. Remove and set aside the cable management devices from the left and right sides of the controller module.
  5. 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.
  6. 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.
  7. Set the controller module aside in a safe place, and repeat these steps for the other controller module in the chassis.
