Managing the FastIron Compact Switch
Managing temperature settings and fan speed on FastIron X Series compact switches
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.
Brocade(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 low temperature threshold of a higher fan speed
must be lower than the high temperature threshold of the lower fan speed. Brocade establishes this guideline to ensure the fan speed
stability.
For example, if you are changing the temperature thresholds for the management module’s high and medium-high fan speeds, the
software will accept the following values because the low temperature threshold for the high speed (67
°
C) is lower than the high
temperature threshold (72
°
C) for the medium-high speed.
However, the software will not accept the following values because the low temperature threshold for the high speed (73
°
C) is higher than
the high temperature threshold (72
°
C) for the medium-high speed.
Changing the device polling interval
The software reads the temperature sensor and polls other hardware sensors according to the value set for the device poll time, which is
60 seconds by default. You can change the device poll time using the CLI.
To change the device poll time, enter a command such as the following at the global CONFIG level of the CLI.
Brocade(config)#chassis poll-time 200
Syntax: chassis poll-time <
value
>
The <value> can be 0 – 65535 (seconds). The default value is 60 seconds.
Displaying the temperature on a FastIron X Series 24-port switch
To view the current temperature readings and warning and shutdown temperature levels, use the
show chassis
command. The following
