Temperature Errors; Monitoring Fan Tray Status - Alcatel-Lucent OmniSwitch 6900 Hardware User's Manual

Monitoring Chassis Temperature

Temperature Errors

The switch monitors the ambient air temperature at all times via an onboard sensor. If an over-temperature
condition occurs, there are two different levels of error severity:
Warning threshold has been exceeded
•
Danger threshold has been exceeded
•
Warning Threshold
If the temperature exceeds the switch's warning threshold, the switch sends out a trap. Traps are printed to
the console in the form of text error messages.
When the warning threshold has been exceeded, switch operations remain active. However, it is
recommended that immediate steps be taken to address the over-temperature condition.
Addressing warning threshold temperature conditions may include:
Checking for a chassis airflow obstruction
•
Checking the ambient room temperature
•
Checking the fan tray status using the
•
Note. For the OS6900's default warning threshold value, refer to the specifications on
warning threshold may be viewed using the show temperature command.
Temperature Danger Threshold
If the chassis ambient air temperature rises above the danger threshold (see specifications on
switch will power off until the temperature conditions have been addressed and the switch is manually
booted. The danger threshold is factory-set and cannot be configured by the user.
Addressing danger threshold temperature conditions may include:
Checking for a chassis airflow obstruction or direction mismatch.
•
Checking the ambient room temperature
•
Checking the fan tray status using the

Monitoring Fan Tray Status

The switch constantly monitors fan operation. If any of the switch's fans unexpectedly shuts down, the
switch sends out a trap and the FAN LED on the chassis front panel displays amber.
To check the switch's current fan tray status, use the
