The operating temperature of your switch is an important factor in its overall health. In order to avoid a 
temperature-related system failure, your switch must always run at an operating temperature between 
0 and 45 degrees Celsius (32 to 113 degrees Fahrenheit). 

To avoid chassis over-temperature conditions, follow these important guidelines:

1 Be sure that your switch is installed in a well-ventilated environment. To ensure adequate airflow, 
leave at least two inches of clearance at the left and right sides.

2 If your switch chassis is not fully populated with uplink or stacking modules, be sure that blank cover 
panels are installed at empty slot positions at all times. Blank cover panels help regulate airflow and thus 
regulate the overall operating temperature in the switch. Refer to 

 for more information.

As with power supply status, the switch constantly monitors the chassis temperature. If a temperature error 
has occurred, the switch sends out a trap to the user and the TEMP LED on the chassis front panel 
displays amber.

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

.

To check the current chassis temperature status, use the 

 command. For example:

-> show temperature

Temperature for chassis 1

  Hardware Board Temperature (deg C)        = 39,

  Hardware Cpu Temperature (deg C)          = N/A,

  Temperature Upper Threshold Range (deg C) = 30 to 77,

  Temperature Upper Threshold (deg C)       = 57,

  Temperature Range                         = UNDER THRESHOLD,

  Temperature Danger Threshold (deg C)      = 77

In the example above, the switch’s current temperature is 39 degrees Celsius. The switch is operating 
under the upper temperature threshold, which is 57 degrees Celsius.
