Replace HIC

When you replace a failed host interface card (HIC) in a controller shelf, you must remove the controller
canister, replace the HIC, and reinstall the controller canister. The following figure shows a 2U controller shelf
with two controller canisters, each with a HIC.

numbers of baseboard ports and HIC ports.

Requirements for adding, upgrading or replacing a HIC

If you plan to add, upgrade, or replace a host interface card (HIC), keep the following requirements in mind.
• 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.)
• The HICs must be compatible with your controllers. The HICs installed in the two controller canisters must
be identical. The presence of mismatched HICs causes the controller with the replacement HIC to lock
down when you bring it online.
• You have all cables, transceivers, switches, and host bus adapters (HBAs) needed to connect the new
host ports. For information about compatible hardware, refer to the
the Lenovo ServerProven website
• You have an ESD wristband, or you have taken other antistatic precautions.
• You have a #1 Phillips screwdriver.
• You have labels to identify each cable that is connected to the controller canister.
• You have installed ThinkSystem Storage Manager on a management station, so you can use the storage
array's command line interface (CLI). If this software has not yet been installed, follow the instructions in
