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.
Steps
- Using a #1 Phillips screwdriver, remove the screws that attach the HIC faceplate to the controller canister.
There are four screws: one on the top, one on the side, and two on the front.

- Remove the HIC faceplate.
- Using your fingers or a Phillips screwdriver, loosen the three thumbscrews that secure the HIC to the controller card.
- Carefully detach the HIC from the controller card by lifting the card up and sliding it back.
Attention: Be careful not to scratch or bump the components on the bottom of the HIC or on the top of the controller card.
