Upgrade host interface card
You install the new host interface card (HIC) to increase the number of host ports or change host
protocol 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 two HICs, that are compatible with your controllers.
• You have removed the HIC that is being upgraded.
About this task
Attention: Possible loss of data access – Never install a
HIC in an EF300 or 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.
Steps
1.
Unpack the new HIC and the new HIC faceplate.
2. Align the single thumbscrew 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.
Note: The image above is an example, the appearance of your HIC may differ.
3. 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.
4. Hand-tighten the HIC thumbscrew.
