To replace the fan module in a switch, do the following:
-
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 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.
