2. With the PSU handle in the open position, slide the module into the enclosure, taking care to support the base and
weight of the module with both hands.
3. Lever the module home by manually closing the PSU handle. You should hear a click as the latch handle engages and
secures the PSU to its connector on the back of the power midplane.
4. Connect the power cable to the power source and the PSU.
Power cables are typically routed to the PSU from the cable management arm (CMA). Verify that the 180º power
cable bends lie flat in the CMA baskets. Route the cables as shown in
they lay flat on the CMA shelf and through the PSU cable clips assembly. See
5. Verify that the bitonal PSU Status LED is ON/green. Verify that cooling fans are spinning with no fail states. Verify
that the front panel LED states show no amber module faults.
6. If replacing two PSUs, repeat
Replacing a system fan module
This section provides procedures for replacing a failed system fan module. Illustrations in system fan replacement
procedures show rear panel views of the enclosure, with the fan properly oriented for insertion into the rear panel of the
enclosure.
If a system fan module fails, the remaining three fans are sufficient to maintain operation of the enclosure. You need not
halt operations and completely power-off the enclosure when replacing only one system fan; however, a complete orderly
shutdown is required if replacing multiple system fan modules simultaneously.
CAUTION: Do not remove the cover from the system fan module due to danger from electric shock inside. Return the
module to your supplier for repair.
See CAUTION bullets regarding electrostatic discharge and anti-static protection on

Removing a system fan module
CAUTION: Removing a system fan module significantly disrupts the enclosure's airflow. Do not remove the fan until
you have received the replacement module. It is important that all fan module slots are filled when the enclosure is in
operation.
1. Move any power cords out of the way of System fan modules.
2. Press down on the latch tab to release the fan from its locked position. See detail No.1 in
