Complementary application of PoE power supply and PoE switch

PSE equipment in using two types of Ethernet power supply: the first kind of PSE combining with PoE power supply function and data exchange function, the PSE power supply terminal to the existing network connection, called the end cross connect (Endpoint) equipment, namely we often say PoE switch.
The second kind of PSE is installed between the network switch and the PD, the PSE power supply is called the middle cross connect equipment, only applies the DC power to the data line.
For cross network based on it for power management, and usually put together and PoE switch and PoE switch, as there are multiple input and output ports of RJ-45, corresponding to two RJ-45 ports each, a cable connected to the Ethernet power supply function does not have the network switching equipment, as the data input port jack; while another RJ-45 as data and power combined output port is connected to remote support PoE power supply power device PD.
At the end of cross connection (Endpoint) is a set of PoE switches, PSE power supply network data exchange and integration together, simple and convenient and space saving equipment, such as video surveillance in the security industry in the PoE switch is widely used in Hong Ruiguangxiang.
POE (PoE) is a revolutionary technology, both in cross PoE switch type PoE power supply or terminal type, they are currently carrying through the Ethernet data line five / five super twisted pair cable provides reliable DC power supply equipment of the power supply network, expansion of Ethernet, the network administrator to maximize the convenience of management in network terminal equipment.
