Replacing a 2U PSU
This section provides procedures for replacing a failed PSU. Illustrations in PSU replacement
procedures show rear panel views of the chassis, with the PSU properly oriented for insertion into the
rear panel of the chassis.
A single PSU is sufficient to maintain operation of the chassis. You need not halt operations and
completely power-off the chassis when replacing only one PSU; however, a complete orderly
shutdown is required if replacing both units simultaneously.
