Configuring the PoE Monitoring Function
After the PoE monitoring function is enabled, the system monitors the parameter values related
to PoE power supply, PSE, PD, and device temperature in real time. When a specific value
exceeds the limited range, the system will automatically take some measures to protect itself.
Configuring PoE Power Supply Monitoring
PoE power supply converts AC power to specific DC power and supplies to PSEs. Exceptions
of AC input voltage and DC output voltage of PoE power supply directly affect the PSEs to
supply power to PDs. You can configure monitoring over AC input voltage and DC output
voltage of PoE power supply. When a specific monitored item reaches the threshold, the system
will generate trap message to notify the administrator of the PoE power supply exception.
Follow these steps to configure PoE power supply monitoring:
