Install host interface card

You install the same model of host interface card (HIC) in the second controller canister, if the currently installed controller includes a HIC.

Before you begin


  1. Unpack the new HIC, and confirm it is identical to the existing HIC.
    Attention: Possible loss of data access – The HICs installed in the two controller canisters must be identical. If the replacement HIC is not identical to the HIC you are replacing, do not attempt this procedure. The presence of mismatched HICs will cause the new controller to lock down when it comes online.
  2. Turn the new controller canister over, so that the cover faces up.
  3. Press the button on the cover, and slide the cover off.
  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.

  9. Reinstall the cover on the controller canister by sliding the cover from back to front until the button clicks.
  10. Set the controller canister aside until you are ready to install it.
