Managing the FastIron Compact Switch

To display the system log, enter the following command at any CLI level:
The default warning temperature is 45° Celsius. The default shutdown temperature is 55° Celsius. These default
temperatures refer to the exhaust side of the device.
Changing the Temperature Warning Level on a FES
The FES sends a warning message whenever the device’s internal temperature reaches the default or configured
warning temperature. You can change the warning temperature using the following command:
FastIron(config)#temperature warning 47
Syntax: temperature warning <value>
The <value> can be 0 – 125° C.
Changing the Shutdown Temperature on a FES
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.
To change the shutdown temperature on a FES, enter the following command:
FastIron(config)#fan-threshold mp speed-1 75
Syntax: [no] fan-threshold mp speed-1 <shutdown-temperature>
Enter 0 – 125° C for <shutdown-temperature>, which is the high mark on the last (highest) speed supported on
that device.
Changing the Chassis Temperature Polling Interval
The software reads the temperature sensor and polls other hardware sensors according to the value set for the
chassis poll time, which is 60 seconds by default. You can change the chassis poll time using the CLI.
To change the chassis poll time, enter a command such as the following at the global CONFIG level of the CLI:
FastIron(config)#chassis poll-time 200
Syntax: chassis poll-time <value>
The <value> can be 0 – 65535.
