Replace power supply (12-drive or 24-drive)

Each 12-drive or 24-drive controller shelf or drive shelf includes two power supplies with integrated fans. These are referred to as power-fan canisters in ThinkSystem System Manager. If a power-fan canister fails, you must replace it as soon as possible to ensure that the shelf has a redundant power source and adequate cooling.

  1. Prepare to replace power supply
    You prepare to replace a power supply in a 12-drive or 24-drive controller shelf or drive shelf by collecting support data about your storage array and locating the failed component. The power supply is referred to as a power-fan canister in ThinkSystem System Manager.
  2. Remove failed power supply
    You remove a failed power supply so you can replace it with a new one. When you remove a power supply (referred to in ThinkSystem System Manager as a power-fan canister), you turn off power, disconnect the power cord, and slide the part out of the shelf.
  3. Install new power supply
    You install a new power supply to replace the failed one. When you install a power supply (referred to in ThinkSystem System Manager as a power-fan canister), you slide the part into the shelf, close the cam handle, reconnect the power cord, and reapply power.
