System USM Firmware
When replacing an FRU, it is possible that the firmware loaded onto the new component does not match the USM release
level of the other components within the system. To ensure optimal system operation, it is important that all components
within the system are running revisions that are from the same USM release. After replacing any system FRUs, ensure
that the system USM firmware and configuration (including SAS zoning) is appropriate for the solution. See
for details.

Replacing a PSU module
This section provides procedures for replacing a failed power supply unit (PSU) module. Illustrations in PSU replacement
procedures show rear panel views of the enclosure, with the PSU properly oriented for insertion into the rear panel of the
enclosure.
A single PSU is sufficient to maintain operation of the enclosure. You need not halt operations and completely power-off
the enclosure when replacing only one PSU; however, a complete orderly shutdown is required if replacing both units
simultaneously.
CAUTION:
Do not remove the cover from the PSU due to danger from electric shock inside. Return the PSU to your
supplier for repair.

TIP:
The illustrations show PSU module replacement as you face the enclosure rear panel. See also
