Extracting and Inserting the Power Supply Unit

With both power supplies installed in the redundant configuration, either PS unit may be
extracted without bringing down the system.
Make sure that the PS unit that you are NOT replacing is showing all green, for both
the PS unit and status indicators.
Fan Air flow direction
Power supply units have directional air flows similar to the fan module. The Fan mod-
ule airflow must coincide with the airflow of all of the PS units. If the PS unit airflow
direction is different from the fan module airflow direction the switch internal temper-
ature will be affected.
