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. The splitter is the silver and black box in the middle between the wiring junction box (left ...
A modern switch may implement power over Ethernet (PoE), which avoids the need for attached devices, such as a VoIP phone or wireless access point, to have a separate power supply. Since switches can have redundant power circuits connected to uninterruptible power supplies, the connected device can continue operating even when regular office ...
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 ...
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 ...
The switch with the lowest priority of all the switches will be the root; if there is a tie, then the switch with the lowest priority and lowest MAC address will be the root. For example, if switches A (MAC = 0200.0000.1111 ) and B (MAC = 0200.0000.2222 ) both have a priority of 32,768 then switch A will be selected as the root bridge.
Ethernet is transparent to the OSes, driver, software, thus ExpEther can work with enormous commodity standard OS, drivers, PCIe devices, Ethernet switches without any modification. It can also control the logical connection of PCI Express among a root and endpoint devices remotely by a management software.
The EtherNet/IP and CIP technologies are managed by ODVA, Inc., a global trade and standards development organization founded in 1995 with over 300 corporate members. EtherNet/IP uses both of the most widely deployed collections of Ethernet standards –the Internet Protocol suite and IEEE 802.3 – to define the features and functions for its ...
The Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It appeared in 1999, in the context of the boom of DSL as the solution for tunneling packets over the DSL connection to the ISP's IP network, and from there to the rest of the Internet.
