To change the warning temperature on a FastIron X Series compact switch, enter a command such as the
following.
FastIron(config)#temperature warning 47
Syntax: temperature warning <value>
The <value> can be 0 – 125° C. Default values are listed in Table 5.2.
Changing the Shutdown Temperature
You can change the shutdown temperature on a FESX, FESX-E, or FWSX switch by changing the temperature for
the highest fan speed.
Changing the Shutdown Temperature on a 24-port Switch
To change the shutdown temperature on a FastIron X Series 24-port switch, enter a command such as the
following:
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 the
device.
Changing the Shutdown Temperature on a 48-port Switch
To change the shutdown temperature on a FastIron X Series 48-port switch, enter a command such as the
following:
FastIron(config)#fan-threshold mp speed-3 35 85
Syntax: [no] fan-threshold mp <highest-speed> <low-temperature-mark> <high-temperature-mark>
Enter “speed-3” for <highest-speed>, which is the highest fan speed available on a 48-port switch. If the switch
has a fan speed higher than 3, enter that fan speed.
For the <low-temperature-mark> and <high-temperature-mark> parameters, you can specify any temperature in
Centigrade. However, when changing low and high temperature thresholds for a fan speed, remember that the
