Remove host interface card

If the controller canister includes a host interface card (HIC), you must remove the HIC from the original controller canister, so you can reuse it in the new controller canister. To remove the HIC you must first remove the faceplate, then loosen the single thumbscrew on the HIC and lift it from the controller.

Before you begin


  1. Using a Phillips screwdriver, remove the two screws that attach the HIC faceplate to the controller canister.

    Note: The image above is an example, the appearance of your HIC may differ.
  2. Remove the HIC faceplate.
  3. Using your fingers or a Phillips screwdriver, loosen the single thumbscrew that secure the HIC to the controller card.

    Note: The HIC comes with three screw locations on the top but is secured with only one.
  4. Carefully detach the HIC from the controller card by lifting the card up and out of the controller.
    Attention: Be careful not to scratch or bump the components on the bottom of the HIC or on the top of the controller card.

  5. Place the HIC on a flat, static-free surface.

After you finish
