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.
What you need to use PoE?
First and foremost it is imperative that the network device supports POE. Look, therefore, always according to whether it is the case for the relevant products. Then you need a power source. A common switch or router is just not normally able to supply power through the network cable, and you therefore need to acquire a so-called PoE switch or PoE injector.
What is a PoE switch?
A PoE-switch is the switch as a standard, except that it is able to deliver current through the network cable. It is also possible to connect network devices that are not PoE compatible, such as a computer without being damaged. Switch find out for yourself whether the connected device is PoE compliant or not.
