Power Supply Fan

Like the controller fan, the power supply fan is a single, removable canister that
contains two cooling fans. The dual fans provide a redundant cooling system to both
power supply canisters. If one fan fails, the other continues to operate, providing
sufficient air circulation to prevent the power supplies from overheating until you
can replace the entire power supply fan canister.
The power supply fan canister goes into a slot on the rear of the controller module,
between the power supplies. Each canister has a locking lever that enables you to
unlatch and remove it from the chassis (
canister: a Power LED and a Fault LED. See
these LEDs.
