Dell PowerConnect Switches: FAN Sensors
|Distribution||Official part of Checkmk|
If a switch has more then one FAN sensor, it will create a service for EACH sensor. However, if a switch has any FANS that are not connected up to the sensor suite, or there is an empty FAN bay, they will not be picked up by this check.
A FAN that is running normally will return an OK nagios state. Any FAN that are in a warning or is not present (if it was previously present) will return a WARNING nagios state. If a FAN is in a critical or is non-functional according to the sensor will return a CRITICAL nagios state. Lastly, if a FAN is in a "shutdown" state, it will return an UNKNOWN nagios state.
Currently, testing has been completed with the Dell PowerConnect 5448 and 5424 models, however the service check may work with other models.
Name of the fan
One service is created for each fan if the MIB defined above is supported on the switch.
