Advantages of PoEz Reliability: The centralized power supply provides backup convenience, unifiedmanagement, and safety.z Easy connection: Network terminals only require an Ethernet cable, but noexternal power supply.z Standard: PoE conforms to the 802.3af standard and uses a globally uniformpower interfaces;z Bright application prospect: PoE can be applied to IP phones, wireless accesspoints (APs), chargers for portable devices, card readers, network cameras, anddata collection system.II. PoE componentsPoE consists of three components: power sourcing equipment (PSE), PD, and powerinterface (PI).z PSE: PSE is comprised of the power and the PSE functional module. It canimplement PD detection, PD power information collection, PoE, power supplymonitoring, and power-off for devices.
