Removing the Switch from the Rack
Before you begin, have the replacement fan module on hand so that you can complete the replacement
promptly. The switch can overheat if left without adequate cooling for an extended time.
To replace the fan module in a switch, do the following.
1. Gently pull the tab (labeled Air Out or Air In) on the end of the fan module.
The fan module is held in place by spring clips. As you pull, the clips will disenagage and the fan will
stop.
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 have red tabs and are labeled Air Out.
Fans with back-to-front airflow have blue tabs and are labeled Air In.
4. Carefully slide the replacement fan module into the switch.
Push until the fan module snaps into place. The fan will automatically start to operate.
