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 .
PoE—Power over Ethernet; PoS—Point of Sale; POCO—Plain Old Class Object; POID—Persistent Object Identifier; POJO—Plain Old Java Object; POP—Point of Presence; POP3—Post Office Protocol v3; POSIX—Portable Operating System Interface, formerly IEEE-IX; POST—Power-On Self Test; PPC—PowerPC; PPI—Pixels Per Inch; PPM—Pages Per ...
Using point-to-point copper cabling provides the opportunity to deliver electrical power along with the data. This is called power over Ethernet and there are several variations defined in IEEE 802.3 standards. Combining 10BASE-T (or 100BASE-TX) with Mode A allows a hub or a switch to transmit both power and data over only two pairs. This was ...
Power over may refer to various forms of powering devices over data links: Power over eSATA (eSATAp), a variant of eSATA also delivering power over the same cable (but not the same wires inside the cable) Power over Ethernet (PoE), a method to power devices over their Ethernet cable (shared wires for data and power) Power over fiber (PoF ...
Extended and automated power management of Power over Ethernet (PoE) end points. Inventory management, allowing network administrators to track their network devices, and determine their characteristics (manufacturer, software and hardware versions, serial or asset number).

Structured cabling network diagram. Structured cabling is the design and installation of a cabling system that will support multiple hardware uses and be suitable for today's needs and those of the future. With a correctly installed system, current and future requirements can be met, and hardware that is added in the future will be supported. [1]
It doesn't currently provide power over the cable, although work is under way to address this using the IEEE802.3af Power over Ethernet (PoE) standard. Foundation Fieldbus was originally intended as a replacement for the 4-20 mA standard, and today it coexists alongside other technologies such as Modbus, Profibus, and Industrial Ethernet ...
