Opening the controller module

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

Steps

  1. If you are not already grounded, properly ground yourself.
  2. 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.
  3. Remove and set aside the cable management devices from the left and right sides of the controller module.


  4. If you left the SFP modules in the system after removing the cables, move them to the new controller module.
  5. Loosen the thumbscrew on the cam handle on the controller module.

    Make sure that you support the bottom of the controller module as you slide it out of the chassis.
