Removing and Replacing Components
To replace the fan module in a switch, do the following.
1. Gently pull the tab (labeled Air Out) 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.
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.
