Abstract The invention provides a power switching apparatus used in a network equipment in order to switch power generated by the Ethernet and an D.C. power supply. The power switching apparatus comprises a first input port used to connect to a first power terminal; a second input port used to connect to a second power terminal; an output port used to output a voltage; a switching circuit connected to the first input port, the second input port and the output port, wherein the switching circuit cuts off the output voltage generated by the first power terminal and outputs the voltage generated by the second power terminal while the second power terminal is plugged into the second input port.
