Power supply radius of PoE switch
Standards-based Power over Ethernet is implemented following the specifications in IEEE 802. In multi-pair cases, PoE supplies power as a over two or more of the The original PoE standard, also known as IEEE 802. Power and data can be delivered simultaneously over Ethernet connections, thanks to a ground-breaking technology called Power over Ethernet (PoE). PoE is an emerging new capability to deliver data and power to internet appliances over existing CAT-5 Ethernet. In this configuration, an Ethernet connection includes Power over Ethernet (PoE) (gray cable looping below), and a PoE splitter provides a separate data cable (gray, looping above) and power cable (black, also looping above) for a wireless access point. For this there are two methods: either by a HW protocol (Physical Layer Classification) or by using the LLDP protocol (Link Layer Discovery Protocol) for data exchange between.
