WARNING: While some factory-approved maintenance on FRUs (e.g. hot-swapping a
PSU, fan, IOM, regulator, or drive) does not require the user to disconnect power to
the system, performing other types of maintenance on systems connected to an
electrical power supply may result in serious injury or death. Only individuals with
knowledge and training in working with devices containing live circuits should operate
the system. Take precautions when performing all other types of maintenance.
Disconnect 2 power supply cords before servicing.
4. Press down on the release tab to release the cam. The release tab cannot be

CAUTION: If both PSUs require replacement and the second PSU is operational,
complete all steps to replace the first PSU, and then follow the same steps to replace
the second PSU.
6. Repeat steps 4 through 6 to remove the second PSU ONLY if both PSUs have
failed and the system is shut down. Otherwise, complete all steps to remove
and install the first PSU, and then repeat all steps to remove and install the
second PSU. If replacing one PSU, skip this step.
