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.
