Step 2: Install host interface card
You install a host interface card (HIC) to replace the failed one with a new HIC.
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. Press the button on the cover of the controller canister, and slide the cover off.
Step 3. Confirm that the green LED inside the controller (by the DIMMs) is off.
If this green LED is on, the controller is still using battery power. You must wait for this LED to go off
before removing any components.

Step 4. Using a #1 Phillips screwdriver, remove the four screws that attach the blank faceplate to the
controller canister, and remove the faceplate.
Step 5. 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 6. 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.
