Monitoring The Cooling System - Brocade Communications Systems FastIron SX Hardware Installation Manual

Changing the temperature polling interval
By default, the Brocade device reads the temperature sensor on each module every 60 seconds. To change the interval at which the
system reads the temperature sensors, enter a command such as the following at the global CONFIG level of the CLI.
device(config)# chassis poll-time 120
Syntax: chassis poll-time seconds
For the second variable, you can specify any number of seconds. If you specify 0, the system reverts to 60 seconds, the default value.
Manually setting the fan speed
NOTE
Use caution when manually setting the fan speed, since this could adversely affect the device's
performance.
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.
device# fan-speed 1
Syntax:fan-speed fan-speed
The 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.
device# show chassis
