PoE (Power over Ethernet) Configuration
PoE technology is a system to pass electrical power safely, along with data, on
Ethernet cabling. Power is supplied in common mode over two or more of the
differential pairs of wires found in the Ethernet cables and comes from a power
supply within a PoE enabled networking devise such as Switch or can be
injected into a cable run with a midspan power supply.
This figure shows all the PoE ‘s status when connect or disconnect to the PD
devise.
¾ PoE Enabled: POE of the port is able to supply power to the attached PD
(Powered Device)
¾ PD Class: Detect the class of PD
¾ Delivering Power (W): Output power.
¾ Current (mA): The status of the port current
¾ Power output voltage per port
¾ Power Budget Percentage of PoE power has been used
