Replacing a Fan Module
To replace the fan module in a switch, do the following:
1. Completely loosen the captive retaining screws on the fan module.
On most switch models, the fan module has two retaining screws at the bottom corners of the
module, as shown in Figure 86.
On some switch models, the fan module has a single retaining screw at the top right corner of the
module.
2. Slide the fan module out of the switch and set it aside.

3. Verify that the airflow direction on the replacement fan module matches that of the installed fan
modules.
Fans with front-to-back airflow are labeled Air Out.
