Chapter 3 Installing the Switch
Removing and Replacing the Fan Assembly
Verifying the Installation
Note To check the operation of the fans, you need to power up the chassis.
Follow these steps to verify that the new fan assembly was installed correctly:
Step 1 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 that the faceplate is flush with the switch back panel.
Step 2 The fan tray LED should light and be green.
Step 3 If after several attempts the fans do not operate, or if you experience trouble with the installation (for instance, if the captive installation screws do not align with the chassis holes), contact the Cisco TAC for assistance.
