4.8 Power over Ethernet (PoE)
PoE provides a way to distribute low-voltage power across the network
using existing copper Ethernet cable to an endpoint PD (Powered Device).
This centralized, reliable source of power allows network devices such as
IP telephones, wireless LAN access points, surveillance cameras, and
other embedded appliances to operate without additional power adapters
or AC outlets.
The first part is used to view the system information of power sourcing
equipment (PSE).
Voltage: current voltage level.
Min Shutdown Voltage: minimum voltage level threshold allowed.
Max Shutdown Voltage: maximum voltage level threshold allowed.
Power Budget: Maximum power available for all ports.
Power Consumption: the actual power consumed from activated ports.
Power Left: Momentary power budget left for used.
The power supply unit (PSU) supports maximum power up
to 225W. The PSE has been allocated 180W (168W + 12W)
and the rest power is used for main-board.
The second part is the port power settings. You can configure the port
power as follows:
Port: select the port to configure
Port State: enable/disable the port power
Priority: set the port priority. Low numeric value indicates a high priority.
Assigning the same priority to different ports will arrange the ports
according to their physical order, with the lower numeric port having the
highest priority. The valid value is from 0 to 47.
Port Status Window: displays the following information for each port
