Power over Ethernet refers to the existing Cat.5 Ethernet cabling infrastructure does not make any changes in the situation, for some IP based terminal (such as IP telephone, network camera etc.) for the transmission of data signals at the same time, it can also provide DC power supply technology for this kind of equipment.
1, the detection of the cable terminal connection is a support IEEE 802.3af standard receiving end equipment.
2, evaluate the power loss of the connection device.
3, start the power supply, starting from a low voltage to the power supply in a configurable time period.
4, power off, and repeat the detection process to detect whether the cable terminal connection equipment.
