Replacing a PSU module
Procedures for the removal and installation of power supply unit modules.
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.
See CAUTION bullets regarding electrostatic discharge and anti-static protection in the ESD precautions section.
