If you removed a HIC from the original controller canister, you must install that HIC in the new controller
canister.
Before you begin
• You must have a replacement controller canister with the same part number as the controller canister you
are replacing.
• You must have a #1 Phillips screwdriver.
• You have an ESD wristband, or you have taken other antistatic precautions.
Step 1. Using a #1 Phillips screwdriver, remove the four screws that attach the blank faceplate to the
replacement controller canister, and remove the faceplate.
Step 2. Align the three thumbscrews on the HIC with the corresponding holes on the controller, and align
the connector on the bottom of the HIC with the HIC interface connector on the controller card.Be
careful not to scratch or bump the components on the bottom of the HIC or on the top of the
controller card.
Step 3. Carefully lower the HIC into place, and seat the HIC connector by pressing gently on the HIC.
Attention: Possible equipment damage – Be very careful not to pinch the gold ribbon connector
for the controller LEDs between the HIC and the thumbscrews.
