Managing the cooling system
4
Typically, the temperature of the thermal planes, in conjunction with the settings of low and high
temperature thresholds, determine the speed of the fans. If desired, you can use the fan-speed
command to manually set the speed of the fans.
For example, to set the speed of all fans to low, enter the following command.
FastIron# fan-speed 1
Syntax: fan-speed <
fan-speed
>
<
fan-speed
> can be one of the following.
1 – low
2 – medium-low
3 – medium
4 – high
Monitoring the cooling system
You can monitor the following aspects of the cooling system:
•
The temperature of the fan control modules
•
The status and speed of the fans
•
The temperature warnings sent to the system log
Displaying the temperature
By default, the Brocade device polls the temperature sensor on each module every 60 seconds to
get the temperature of each module. The Brocade device records the
highest
temperature reading
of the modules in each thermal plane.
The show chassis command displays the temperature reading of each thermal plane, as shown in
the following examples.
This following shows an example output on the FSX.
The following shows an example output on the
FSX 800
. The output is similar on the
FSX 1600
