Power over Ethernet (PoE) describes any of several standards or ad hoc systems that pass electric power along with data on twisted-pair Ethernet cabling. This allows a single cable to provide both a data connection and enough electricity to power networked devices such as wireless access points (WAPs), IP cameras and VoIP phones .
20 or 44 Gb port switch, and 4 x Dual Personality Ports (2 x Gb or SFPs). Also capable of supporting 10GE ports. 20 or 44 10/100 port switches with two models supportingPoE functionality, and 4 x Dual Personality Ports (2 x Gb or SFPs).

A one-way system might be lower-cost than a two-way system, but also is difficult to reconfigure should the operating environment change. In a two-way system (supporting both outbound and inbound), commands can be broadcast out from the master station to end devices (meters) – allowing for reconfiguration of the network, or to obtain readings ...
