The default maximum PoE 
power is 6720. 

 

The maximum PSE power is the sum of power that the PDs connected to the PSE can get. 

Follow these steps to configure the maximum PSE power: 

Enter system view

Optional 

The default maximum power of 
the PSE is 37. 

 

 

z 

To avoid PSE power interruption due to PoE power overload, ensure that the sum of power of all 

PSEs is less than the maximum PoE power.   

z 

The maximum power of the PSE must be greater than or equal to the sum of maximum power of 

all critical PoE interfaces on the PSE to guarantee the power supply to these PoE interfaces. 

 

The maximum PoE interface power is the maximum power that the PoE interface can provide to the 

connected PD. If the power required by the PD is larger than the maximum PoE interface power, the 

PoE interface will not supply power to the PD. 

Follow these steps to configure the maximum PSE power (distributed IRF device):
