The working process of outdoor PoE switch

Outdoor PoE switch is to support the network cable power supply switch, which can not only achieve the general data transfer function of the switch can also supply power to the network terminal.

When POE switches are arranged in a network, the Power over Ethernet switch works as follows:

1, detection: at first, the POE switch in the port output voltage is very small, until it detects the cable terminal is connected to a support for the IEEE802.3af standard terminal equipment.

2. PD device classification. ,

3, start the power supply.

4, power off: if the PD device is disconnected from the network, the POE switch will quickly stop power supply to the PD device, and repeat the detection process to detect whether the cable terminal is connected to the PD device.
