What is Power Over What is Power Over EthernetEthernet

Power over Ethernet (PoE) is the ability for the LAN switching Power over Ethernet (PoE) is the ability for the LAN switching infrastructure to provide power over a copper Ethernet cable to infrastructure to provide power over a copper Ethernet cable to an endpoint (Powered Device). an endpoint (Powered Device).

As Wireless networking emerged, Power over Ethernet was also As Wireless networking emerged, Power over Ethernet was also used to power these devices to allow for deployments in locations used to power these devices to allow for deployments in locations where local power access did not exist. While IP telephones and where local power access did not exist. While IP telephones and wireless access points are the most intuitive uses for PoE, the wireless access points are the most intuitive uses for PoE, the advent of advent of 802.3af802.3af standardization of PoE opens the door to a new standardization of PoE opens the door to a new generation of networked-attached devices such as video cameras, generation of networked-attached devices such as video cameras, point-of-sale devices, security access control (card scanners), point-of-sale devices, security access control (card scanners), building automation and industrial automation just to name a building automation and industrial automation just to name a few.few.
