Install new controller

You install a new controller canister to replace the failed one. Perform this task only if your storage array has two controllers.

  1. Install battery
    You must install the battery into the replacement controller canister. You can install the battery that you removed from the original controller canister or install a new battery that you ordered.
  2. Install host interface card
    If you removed a HIC from the original controller canister, you must install that HIC in the new controller canister.
  3. Install new controller canister
    After installing the battery and the host interface card (HIC), if one was initially installed, you can install the new controller canister into the controller shelf.
