SeeUpgrading the PSE Processing Software of Fabric Switches Online for details.PoE OverviewIntroduction to PoEPower over Ethernet (PoE)-enabled devices use twisted pairs through electrical ports tosupply power to the remote powered devices (PD) in the network and implement powersupply and data transmission simultaneously.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 no externalpower supply.z Standard: PoE conforms to the 802.3af standard and uses a globally uniform powerinterfaces;z Bright application prospect: PoE can be applied to IP phones, wireless access points(APs), chargers for portable devices, card readers, network cameras, and datacollection system.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 can implementPD detection, PD power information collection, PoE, power supply monitoring, andpower-off for devices.
