Changing the temperature warning level
To change the temperature at which the device sends a syslog message and an SNMP trap, enter a
command similar to the following at the Privileged EXEC level of the CLI.
Brocade# temperature warning 1 82
Syntax:
temperature warning
stack-idvalue
The
stack-id
can be a value from 1 through 12.
The
value
variable is the temperature warning level, in Celsius. You cannot set this level higher than the
maximum value allowed by your device. The temperature warning level must be at least five Celsius
degrees less than the temperature shutdown level, which is automatically set by the device.
The following console and syslog message is displayed when the temperature reaches the warning
level:
!!! Temperature is over warning level on stack unit 1!!!
Temperature shutdown levels
When the temperature crosses the critical (shutdown) threshold levels, the device will reset after 5
minutes. The following console and syslog message is displayed:
!!! Temperature is over shutdown level, please shutdown your stack unit 1 to avoid hw
damage!!!
NOTE
Brocade recommends that you shut down your stack unit to avoid any hardware damage.
Changing the temperature poll time
By default, the software polls the temperature sensor every 60 seconds to get the current temperature.
This poll rate is controlled by the device poll time, which also controls how often the software polls other
system components.
