Install host interface card
You install the new host interface card (HIC) to increase the number of host ports in your storage array.
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 HB5000 controller canister if
that HIC was designed for another ETERNUS AB/HB 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 will cause the controllers to lock down when you apply power.
Procedure
1. Unpack the new HIC and the new HIC faceplate.
2. Using a #1 Phillips screwdriver, remove the four screws that attach the HIC faceplate to the controller
canister, and remove the faceplate.
3. 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.
4. 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.
