Go to Replace host interface card.
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
two-controller configuration, repeat all steps to remove the second controller canister, install the second
HIC, and reinstall the second controller canisters.
Step 1: 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 two-controller configuration, this is because 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.
Step 1. Label each cable that is attached to the controller canister.
Step 2. Disconnect all the cables from the controller canister.
