Changing The Temperature Polling Interval; Manually Setting The Fan Speed; Monitoring The Cooling System; Displaying The Temperature - IBM s-series Installation And User Manual

Changing the temperature polling interval

By default, the 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:
FastIron(config)# chassis poll-time 120
Syntax: chassis poll-time <seconds>
For the <seconds> parameter, 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
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:
1 - low
2 - medium-low
3 - medium
4 - high

Monitoring the cooling system

You can monitor the following aspects of the cooling system:
v The temperature of the fan control modules
v The status and speed of the fans
v The temperature warnings sent to the system log

Displaying the temperature

By default, the device polls the temperature sensor on each module every 60
seconds to get the temperature of each module. The 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.
The following shows an example output on the B08S. The output is similar on the
B16S.
