Introduction to PoE

Power over Ethernet (PoE)-enabled devices use twisted pairs through electrical ports to
supply power to the remote powered devices (PD) in the network and implement power
supply and data transmission simultaneously.
Advantages of PoE
Reliability: The centralized power supply provides backup convenience, unified
management, and safety.
Easy connection: Network terminals only require an Ethernet cable, but no external
power supply.
Standard: PoE conforms to the 802.3af standard and uses a globally uniform power
interfaces;
Bright application prospect: PoE can be applied to IP phones, wireless access points
(APs), chargers for portable devices, card readers, network cameras, and data
collection system.
PoE components
PoE consists of three components: power sourcing equipment (PSE), PD, and power
interface (PI).
PSE: PSE is comprised of the power and the PSE functional module. It can implement
PD detection, PD power information collection, PoE, power supply monitoring, and
power-off for devices.
