Using the Temperature Sensor on a FES
The FES compact switch comes with a built-in temperature sensor. The temperature sensor causes the device to
generate a Syslog message and SNMP trap if the temperature exceeds a specified warning level or shutdown
level.
The software reads the temperature sensor according to the chassis poll time, which is 60 seconds by default. If
the temperature equals or exceeds the shutdown temperature for five consecutive polls of the temperature by the
software, the software will shut down the device to prevent damage.
You can use the CLI or Web management interface to do the following:
• Display the temperature of the device
• Change the warning and shutdown temperature levels
• Change the chassis poll time
Displaying the Temperature on a FES
By default, the software polls the temperature sensor every 60 seconds to get the current temperature. This poll
rate is controlled by the chassis poll time, which also controls how often the software polls other system
components.
To display the temperature of the device, enter the following command at any level of the CLI:
Syntax: show chassis
Displaying Temperature Messages on the FES
The software sends a Syslog message and an SNMP trap if the temperature crosses the warning or shutdown
thresholds. The following methods describe how to view the system log on the device. If you have configured the
device to use a Syslog server or SNMP trap receiver, see the documentation for the server or receiver.
