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. Remove the controller module from the chassis:
    1. Insert your forefinger into the latching mechanism on either side of the controller module.
    2. Press down on the orange tab on top of the latching mechanism until it clears the latching pin on the chassis.
      The latching mechanism hook should be nearly vertical and should be clear of the chassis pin.
    3. Gently pull the controller module a few inches toward you so that you can grasp the controller module sides.
    4. Using both hands, gently pull the controller module out of the chassis and set it on a flat, stable surface.
  6. Repeat these steps for the other controller module in the chassis.
