Reversing the Fan Module Airflow

If the SSA switch rack configuration requires the airflow to be from the power supply side to the I/O port side, you must reverse the airflow in the switch fan modules for both switch fan module 1 and switch fan module 2.

To reverse the airflow in the fan modules, perform the steps in the following topics:

• Removing the Fan Module
• Reversing the Fan Unit
• Reinstalling the Fan Module
