PoE Settings
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.
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.
PoE Priority Example:
Given: A 48 port device is supplying a total of 375 watts.
The administrator configures all ports to allocate up to 30 watts. This results in 48 times 30 ports equaling
1440 watts, which is too much. The device cannot provide enough power to each port, so it provides power
according to the priority.
The administrator sets the priority for each port, allocating how much power it can be given.
These priorities are entered in the PoE Settings page.
