PoE / PoE +
Many different network devices signify that they support PoE. PoE is an abbreviation for Power Over Ethernet, but what does it mean then and what can you use it for.
PoE involves powering network devices directly through a network cable. That is, you do not need to connect both a network cable and a power cord to the device. It is very useful if you want to avoid more wires than absolutely necessary, but it is also useful because it is easier not to have to think about pulling power when pulling cables.
