Install host interface card

Install the host interface card (HIC) to increase the number of host ports in your storage array.

Before you begin

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.
  1. Unpack the new HIC and the new HIC faceplate.
  2. Press the button on the cover of the controller canister, and slide the cover off.
  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.

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

  7. Hand-tighten the HIC thumbscrews.
    Do not use a screwdriver, or you might over tighten the screws.
  8. Using a #1 Phillips screwdriver, attach the new HIC faceplate to the controller canister with the four screws you removed previously.
