fltEquipmentChassisThermalThresholdCritical
Fault Code
F0409
Description
-
Front Panel Thermal Threshold at upper critical levels: Check Cooling.
-
The Front Panel temperature has crossed upper critical threshold: Check device cooling.
-
Riser [Id] inlet temperature has crossed upper critical threshold: Check device cooling.
-
Riser [Id] outlet temperature has crossed upper critical threshold: Check device cooling.
Explanation
This fault occurs when a component within a chassis operates outside the safe thermal operating range.
Recommended Action
If you see this fault, take the following actions:
-
Review the Cisco UCS Site Preparation Guide and make sure that the server has adequate airflow, including front and back clearance.
-
Verify that the airflow to the server is not blocked.
-
Verify that the site cooling system is operating properly.
-
Clean the installation site at regular intervals to avoid buildup of dust and debris, which can cause a system to overheat.
-
Check the temperature readings and make sure it is within the recommended thermal safe operating range.
-
If the fault reports a "Thermal Sensor threshold crossing in the front or back pane" error for the servers, check whether thermal faults have been raised. These faults provide details of the thermal condition.
-
If the fault reports a "Missing or Faulty Fan" error, check the status of the fan.
-
If the fan needs replacement or the problem still persists, create a tech-support file and contact Cisco TAC.
