The POE switch power supply adapter includes a switch power supply circuit, a power supply input circuit, a detection circuit, a power supply output circuit, and a to-be-powered network device. The power supply input circuit is connected with an Ethernet interface, and can convert and input the voltage provided by the Ethernet interface. The input terminal of the power supply output circuit is connected with the output terminal of the power supply input circuit. The output terminal of the power supply output circuit is connected with the to-be-powered network device. The detection circuit is connected with the output terminal of the power supply input circuit and the power supply output circuit. The POE switch power supply adapter possessing the voltage detecting function is easy to install, so the installation is simplified, and the device cost and the management cost are greatly reduced. The network device can be arranged at any position, so the installation flexibility is improved. The network device can work normally as long as the electric power of a switch end is not cut off, so the wire connection of the network device is saved, and the network structure is simplified.
