To replace the fan module in a switch, do the following:
-
Completely loosen the captive retaining screws on
the fan module.

screws at the bottom corners of the module, as shown in Removing a Fan Module.
On some switch models, the fan module has a single
retaining screw at the top right corner of the module.
-
Slide the fan module out of the switch and set it
aside.
-
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.
Fans with back-to-front airflow are labeled Air In.
-
Carefully slide the replacement fan module into
the switch.
-
Align and fully tighten the captive retaining
screws.
