Маршрутизаторы с питанием через PoE

PoE

— by itself, PoE (Power over Ethernet) technology makes it possible to transfer not only data over an Ethernet network cable, but also energy to power network devices. And the presence of a PoE input allows the router itself to receive power in a similar way. Note that there are special devices - the so-called PoE injectors - that allow you to add power to a regular network signal (that is, add PoE support to equipment that does not initially have such a function).
