extracted without bringing down the system.

See Section 3.3 on page 20 for more information on air flow direction.
If you are not immediately installing a new PSU you must install a blank so that the air flow for
cooling the switch is not compromised.
Make sure that the PS unit that you are NOT replacing is showing all green, for both
the PS unit and status indicators.

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.
