Replace power supply (24-drive)
Each 24-drive controller shelf or drive shelf includes two power supplies with integrated fans. These
are referred to as
power-fan canisters
in SANtricity 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.
