Removing the HICs (if upgrading only the HICs)
If you are upgrading the HICs (instead of replacing the controller canisters), you must remove the HICs from both controller
canisters before you can upgrade the host protocol.
Before you begin
You must have an ESD wristband or have taken other antistatic precautions.
Steps
1. Remove the top cover from controller A.
Press down on both the top-cover latch buttons, and slide the top cover to the rear.
2. Remove the four screws for the HIC faceplate using a Phillips screwdriver, and remove the faceplate from the controller
canister.
3. Unscrew the three thumbscrews that secure the HIC to the controller card.
If the thumbscrews are overly tightened, use a Phillips screwdriver.
4. Detach the HIC from the controller card by lifting it up and gently sliding back.
