Managing temperature settings

This section describes how to display temperature settings on the device and how to change the
temperature warning and shutdown levels.

Using the temperature sensor

The device ships with three built-in temperature sensors that cause the device to generate a Syslog
message and SNMP trap if the temperature exceeds a specified warning level or shutdown level. If
the device temperature exceeds the safe threshold (shutdown level), the device will reboot.
The software reads the temperature sensors based on the device poll time, which is by default 60
seconds. If the temperature equals or exceeds the shutdown temperature for five consecutive polls
by the software, the software will reboot the device to prevent damage.
You can use the CLI or Web management interface to perform the following tasks:

Displaying the temperature
By default, the software polls the temperature sensor every 60 seconds to get the current
temperature. This poll rate is controlled by the device poll time, which also controls how often the
software polls other system components.
To display the temperature of a device, enter the show chassis command at any level of the CLI.
