Managing the cooling system
5
Changing the temperature polling interval
By default, the router reads the temperature sensor on each module every 60 seconds. To change
the polling interval, enter the temp-poll-period command at the global CONFIG level of the CLI.
Brocade(config)# temp-poll-period 120
Syntax: temp-poll-period seconds
For the seconds parameter, you can specify a value from 30 – 120.
Adjusting temperature polling interval out of the default setting can negatively affect the efficient
cooling of blades and may cause a blade to overheat and shutdown.
Manually setting the fan speed
Typically, the management module, in conjunction with default settings of low and high
temperature thresholds, determines the speed of the two four-speed fans. (For information about
changing the low and high temperature thresholds, refer to “Changing temperature thresholds for
modules and fan speeds” on page 164.) You can manually set the fan speed using the
set-fan-speed command in the Global CONFIG level of the CLI.

a. The four sensors may be displayed in the show chassis command output as Sensor1, Sensor2, Sensor4, and
Sensor5. In that case, Sensor4 and Sensor 5 refer to the LP and LP XPP sensors on the second traffic manager, TM 1.
