POE (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, wireless LAN access point AP network camera, etc.) for the transmission of data signals at the same time, but also to provide such equipment technology of.POE DC power supply at the same time can ensure the safety of the existing structured cabling to ensure the normal operation of the existing network, minimizing the cost.
POE switch port supports output power up to 15.4W or 30W, in line with the IEEE802.3af/802.3at standard, through the cable power supply mode to the standard POE terminal equipment of the power supply, without the need for extra power wiring. With IEEE802.3atPOE switch port, the output power can reach 30W, the electric power can be obtained by the 25.4W. is popular to say, is to support POE switch cable the power supply switch, which can not only realize the function of data transmission can also ordinary switches for supplying power to the network terminal.
The POE switch is support for the cable power supply switch, and the switch is compared by ordinary electric terminals (such as AP, digital camera etc.) without further power routing, reliability of the whole network is higher. Which is a relatively good S1626-PWR switch H3C, the power supply can be through the people of each port and the interface of the PoE the equipment was simple, and the price is very competitive!
