Shutdown warning messages
If any thermal plane exceeds the shutdown temperature level, the Brocade device will display a
shutdown warning message on the console every five seconds until either the temperature level
goes back down below the shutdown temperature level, or the system shuts down the chassis to
prevent further damage (shutdown occurs after five minutes of exceeding the shutdown
temperature level).
The shutdown warning messages indicate the thermal plane that triggered the warning and the
number of seconds before the device will shut down. The following shows an example warning
message.
!!! Temperature of SWITCH FABRIC CARDS THERMAL PLANE is over shutdown level,
system is going to be shutdown in 300 seconds !!!
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.
FastIron(config)# chassis poll-time 120
Syntax: chassis poll-time <
seconds
>
For the <
seconds
> 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.
