Viewing Fan Status
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 “Status LEDs” on page 2-18 .
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.
Viewing Fan Status for Stacked Configurations
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:
