The following counters are displayed for each device:

•

Nominal Power—The total amount of power the device can supply to all the 
connected PDs.

•

Consumed Power—Amount of power currently being consumed by the PoE 
ports.

•

Available Power—Nominal power minus the amount of consumed power.

Click Apply to save the PoE properties.

The PoE Settings page

 

displays system PoE information for enabling PoE on the 

interfaces and monitoring the current power usage and maximum power limit per 
port.

PoE can be configured on the device for a specific period. This feature enables you 
to define, per port, the days in the week and the hours that PoE is enabled. When 
the time range is not active, PoE is disabled. To use this feature, a time range must 
first be defined in the 

Click Port Management > PoE > Settings.

This page limits the power per port in two ways depending on the Power Mode: 

•

Port Limit: Power is limited to a specified wattage. For these settings to be 
active, the system must be in PoE Port Limit mode. That mode is configured 
in the PoE Properties page.

When the power consumed on the port exceeds the port limit, the port 
power is turned off.

•

Class Limit: Power is limited based on the class of the connected PD. For 
these settings to be active, the system must be in PoE Class Limit mode. That 
mode is configured in the PoE Properties page.

When the power consumed on the port exceeds the class limit, the port 
power is turned off.

Given: A 48 port device is supplying a total of 375 watts.
