Optional
The default DC output
over-voltage threshold is 55.00.
The under-voltage threshold should be less than the over-voltage threshold.
Configuring PSE Power Monitoring
When the PSE power exceeds or drops below the specified threshold, the system will send trap
message.
Follow these steps to configure a power alarm threshold for the PSE:

Monitoring PD
When a PSE starts or ends supplying power to a PD, the system will send a trap message.
Configuring PoE Interface through PoE Profile
You can configure a PoE interface in either of the following two ways:
z
Using command lines.
z
Using a PoE profile, and applying the PoE profile to the specified PoE interface(s).
When configuring a single PoE interface, you can use command lines; when you configure PoE
interfaces in batches, you can use a PoE profile.
A PoE profile is a collection of configurations, containing multiple PoE features. On large-scale
networks, you can apply a PoE profile to multiple PoE interfaces, and thus these interfaces have the
same PoE features. If the PoE interface connecting to a PD changes to another one, you just need to
apply the PoE profile applied on the originally connected interface to the currently connected interface
instead of reconfiguring the features defined in the PoE profile one by one, thus simplifying the PoE
configurations.
You can define PoE configurations based on each PD, save the configurations for different PDs into
different PoE profiles, and apply the PoE profiles to the access interfaces of PDs accordingly.
