Install a Fan Module

Installing a fan module is a hot-swap operation. You do not need to power off the switch before installing the fan module.

1. If you are replacing a fan module, remove the faulty or obsolete fan module first, then return to Step 2 of this task.

   See Remove a Fan Module.

2. Align the fan module to the opening in the switch chassis with the thumbscrew on the right.
   
3. Firmly slide the fan module into the chassis until the fan module stops.

   The fan module immediately powers on.

4. Tighten the captive thumbscrew to secure the fan module in the switch chassis.
   
5. Verify that the fan module Attention LED goes out.
   • If the Attention LED stays on, see Verify a Fan Module.
   • If the Attention LED goes out, go to Step 6.
6. Consider your next task.
   • If you have a full-time SER MGT connection, connect the SER MGT cable.

     See Connect the SER MGT Cable.

   • If you do not have a SER MGT connection, install the air duct assembly.

     See Install the Air Duct Assembly.
