The switch also constantly monitors fan operation. If any of the three fans unexpectedly shuts down, the 
switch sends out a trap to the user and the FAN LED on the chassis front panel displays amber.

Note. For detailed LED information, including the FAN LED, refer to 

To check the current fan status, use the show fan command. For example:

-> show fan

Chassis Fan  Status

-------+---+-----------

   1     1   Running

   1     2   Running

   1     3   Running

In the example above, all three fans are operating normally.

When entering the show fan command on the primary switch in a stacked configuration, you can either 
enter only the show fan syntax or you can specify a specific slot number. For more information, refer to 
the examples below:

If you specify a slot number after the command syntax, fan status information for only the corresponding 
switch displays. For example:

-> show fan
Chassis Fan  Status
-------+---+-----------
   1     1   Running
   1     2   Running
   1     3   Running

In the example above, fan status displays only for the switch operating in slot 3.
