Configure a DC output 
over-voltage threshold for the 
PoE power supply (distributed 
IRF device) 

poe-power output-threshold 
chassis chassis-number 
upper value 

Optional 

The default DC output 
over-voltage threshold is 55.00.

 

 

The under-voltage threshold should be less than the over-voltage threshold. 

 

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:

Optional 

80% by default. 

 

When a PSE starts or ends supplying power to a PD, the system will send a trap message. 

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. 

Follow these steps to configure a PoE profile:
