Removing and Installing Components
Verifying the Fan Module
To verify that the new fan module is installed correctly, follow these steps:
Step 1 Listen for the fans; you should immediately hear them operating. If you do not hear them, ensure that
the fan module is inserted completely in the switch and the faceplate is flush with the switch back panel.
Step 2 Verify that the Fan module LED is green. If the LED is orange then one fan has failed in this fan module;
if the LED is red, then both fans have failed in this fan module.
Step 3 Contact your customer service representative for assistance if, after several attempts, the fans do not
operate or you experience trouble with the installation.
Note Verify that the transceiver and cable type both have LC connectors and are the required type for
longwave or shortwave transmission and the required distances. The transceiver label generally
lists the model and wavelength.
