Using Redundant Management Modules
December 2000 5 - 33
Temperature Sensor
The redundant management module contains a temperature sensor. Depending on the temperature reported by
the sensor, the software can send a warning if the temperature exceeds the normal threshold and can even shut
the module down if the temperature exceeds the safe threshold. The software reads the temperature sensor
according to the chassis poll time, which is 60 seconds by default.
When the software reads the temperature sensor, if the temperature equals or exceeds the warning or shutdown
temperature, the software does the following:
• Warning message – If the temperature of the module reaches the warning value, the software sends a Syslog
message to the Syslog buffer and also to the SyslogD server, if configured. In addition, the software sends an
SNMP trap to the SNMP trap receiver, if you have configured the device to use one.
• Shutdown – If the temperature matches or exceeds the shutdown temperature, the software sends a Syslog
message to the Syslog buffer and also to the SyslogD server if configured. The software also sends an
SNMP trap to the SNMP trap receiver, if you have configured the device to use one.
If the temperature equals or exceeds the shutdown temperature for five consecutive polls of the temperature by
the software, the software shuts down the module to prevent damage.
You can display the temperature of the module. You also can change the warning and shutdown temperatures
and the chassis poll time.
Displaying the Temperature
By default, the software polls the temperature sensor on the active redundant management module every 60
seconds to get the current temperature. This poll rate is controlled by the chassis poll time, which also controls
how often the software polls other system components. You can display the temperature of the active redundant
management module using either of the following methods.
USING THE CLI
To display the temperature of a redundant management module, enter the following command at any level of the
CLI:
BigIron> show chassis
power supply 1 not present
power supply 2 not present
power supply 3 ok
power supply 4 not present
power supply 1 to 4 from bottom to top
fan 1 ok
fan 2 bad
fan 3 ok
fan 4 ok
Current temperature : 34.5 C degrees
Warning level : 45 C degrees, shutdown level : 55 C degrees
Syntax: show chassis
