Removing the controller module

You must remove the controller module from the chassis when you replace a component inside the controller module.

Make sure that you label the cables so that you know where they came from.

A video for this task is available at:
  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. Remove the storage and networking cables.
  5. Insert your forefinger into the latching mechanism on either side of the controller module, press the lever with your thumb, and gently pull the controller a few inches out of the chassis.
    Note
    If you have difficulty removing the controller module, place your index fingers through the finger holes from the inside (by crossing your arms)
