EIRP Industrial Unmanaged Power over Ethernet Switches

PoE stands for Power over Ethernet, which is just what it says. Power is transmitted over the Ethernet cable along with the data lines. Each PoE switch has a set of ports that is classified as power source equipment (PSE). These ports can be used to power IEEE 802.3af compliant powered devices (PD), eliminating the need for a separate power line to be run to each end device.
