Replace host interface card

You replace a host interface card (HIC) to replace the failed HIC with a new one. If you are replacing HICs in
a duplex configuration, repeat all steps to remove the second controller canister, install the second HIC, and
reinstall the second controller canister.
Remove controller canister
You remove the controller canister so you can add the new host interface card (HIC). When you remove a
controller canister, you must disconnect all cables. Then, you can slide the controller canister out of the
controller shelf.
Before you begin
• You have scheduled a downtime maintenance window for this procedure. The power must be off when
you install HICs, so you cannot access data on the storage array until you have successfully completed this
procedure. (In a duplex configuration, both controllers must have the same HIC configuration when they
are powered on.)
• You must use labels to identify each cable that is connected to the controller canister.
• You have an ESD wristband, or you have taken other antistatic precautions.
Procedure
1. Label each cable that is attached to the controller canister.
2. Disconnect all the cables from the controller canister.
Attention: To prevent degraded performance, do not twist, fold, pinch, or step on the cables.
3. Confirm that the Cache Active LED on the back of the controller is off.
The green Cache Active LED on the back of the controller is on when cached data needs to be written to the
drives. You must wait for this LED to turn off before removing the controller canister.
