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 Removing a Fan Module.

    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.
