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.
device(config)# temp-poll-period 120
Syntax: temp poll period log threshold
seconds
For the
seconds
parameter, you can specify a value from 30 - 120.
NOTE
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 207.) You can manually set the fan speed using the set-fan-speed command in the
Global CONFIG level of the CLI.
NOTE
Auto control of fan speed is not monitored when cards are in interactive mode. Set fan speed to high to prevent over-temp
condition.
NOTE
Setting a value other than auto or high disables auto fan control and will negatively affect the efficient cooling of blades and
may cause a blade to overheat and shutdown.
