Perform these steps when checking the installation to verify that the new fan
assembly is installed correctly:
Listen for the fans; you should immediately hear them operating. If you do not
hear them, ensure that the fan assembly is inserted completely in the chassis and
the faceplate is flush with the switch back panel.
Verify that the FAN STATUS LED is green. If the LED is red, one or more fans
are faulty.
If after several attempts the fans do not operate or you experience trouble with the
installation (for instance, if the captive installation screws do not align with the
chassis holes), contact a Cisco customer service representative for assistance.
