Before you begin
• You have an ESD wristband, or you have taken other antistatic precautions.
• You have a #1 Phillips screwdriver.
• You have one or two HICs, based on whether you have one or two controllers in your storage array. The
HICs must be compatible with your controllers.
Attention: Possible loss of data access – Never install a HIC in a controller canister if that HIC was
designed for another DE Series controller. In a two-controller configuration, both controllers and both HICs
must be identical. The presence of incompatible or mismatched HICs will cause the controllers to lock down
when you apply power.
Step 1. Unpack the new HIC and the new HIC faceplate.
Step 2. Using a #1 Phillips screwdriver, remove the four screws that attach the HIC faceplate to the
controller canister, and remove the faceplate.
