After you finish
Go to Step 2: Install host interface card on page 110.
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.
About this task
Attention: Possible loss of data access – Never install a HIC in an E5700 controller canister if
that HIC was designed for another E-Series controller. In addition, if you have a duplex
configuration, 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.
Steps
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.

controller canister, and remove the faceplate.
