Many different network devices even display that supports PoE. PoE stands for Power Over Ethernet, but what does that mean and what can you do with it.
PoE is to add network devices powered directly through a network cable. This means that you do not need to connect both network cable and a power cable to the device. It is very useful if you want to avoid more wires than necessary, but it is also useful because it is easier not having to worry about pulling power when pulling cables.
