Add the new host interface card

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

Before you begin

About this task

Attention: Possible loss of data access – Never install a HIC in an EF600 controller canister if that HIC was designed for another E-Series controller. In addition, both controllers and both HICs must be identical. The presence of incompatible or mismatched HICs causes the controllers to lock down when you apply power.


  1. Remove the controller canister's cover by unscrewing the single thumbscrew and lifting the lid open.
  2. Confirm that the green LED inside the controller 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.
  3. Using a #1 Phillips screwdriver, remove the two screws that attach the HIC faceplate to the controller canister, and remove the faceplate.
  4. Align the single thumbscrew on the HIC with the corresponding hole 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.
  5. 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 thumbscrew.

    Note: The image above is an example of an EF600, the appearance of your HIC may differ.
  6. Hand-tighten the HIC thumbscrew.
    Do not use a screwdriver, or you might over tighten the screws.
  7. Using a #1 Phillips screwdriver, attach the HIC faceplate you removed from the original controller canister to the new controller canister with the two screws.
