Abstract: Systems and methods are provided for network expansion. In one embodiment of the present invention, a system is provided having a network connection device, a first network device, and a second network device. The first network device and the second network device may be coupled together in a network topology configured so that a single port on the network connection device supports network connectivity to both the first network device and second network device. The single port may provide power and data to an input port on the first network device. An output port on the first network device may provide power and data to the second network device. The network connection device may be a Power over Ethernet switch.
