Managing temperature settings
The device contains temperature sensors that the software reads based on a configurable device poll
time. The devices have two automatic speed fan control settings based on the temperature. To protect
the device from overheating, the following temperature threshold levels exist:
• The warning level is the temperature at which the device generates a syslog message. It is
configurable up to 100°C.
• The shutdown level is the temperature at which the device reboots. It is set by the device and is not
configurable. When the device temperature reaches the shutdown level, it generates a warning
message that the device’s temperature is over the shutdown level and the device will shut down in
five minutes. The system restarts five minutes after the device reaches the temperature shutdown
level.

Displaying the temperature
To display the temperature of a device, enter the
show chassis
command at any level of the CLI. The
show chassis
command displays the power supply status and temperature threshold levels for fan
speed.
NOTE
The displayed temperature reflects the temperature of the board inside the device.
