side of power cord connects to the power outlet. The internal power supply of the Switch works with voltage range of AC in the
Network Application 
The Power over Ethernet Hub can provides power to the PD that follow the IEEE 802.3af standard in the network. It can solve the problem of position limitation. The network device can be installed in more appropriate position for better performance. The following figure is an example of network application for Power over Ethernet Hub.
