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
To remove the switch fan module, follow these steps:
1 Unscrew the two fan module captive screws as shown in
2 Slide the fan module forward until it is unplugged from the device.

Reversing the Fan Unit
The switch fan module has a single reversible dual fan unit. When the fan unit is properly seated, the
airflow indicator arrow is completely visible as shown in callout 1,
on page 16. The airflow
indicator arrow points in the direction the fan unit flows air through the fan module.
In the I/O port to power supply module (default) airflow configuration, the fan unit is visible (as shown
in
on page 15, callout 4).
