Monitoring Temperature

The Cisco Catalyst Blade Switch 3020 for HP monitors the switch temperature conditions.
Use the show env temperature status privileged EXEC command to display the temperature value,
state, and thresholds. The temperature value is the temperature in the switch (not the external
temperature).You can configure only the yellow threshold level (in Celsius) by using the system env
temperature threshold yellow value global configuration command to set the difference between the
yellow and red thresholds. You cannot configure the green or red thresholds. For more information, see
the command reference for this release.
