4.2.1.2 PoE Switch Unit

Power over Ethernet (PoE) is a technology that passes electrical power along an

Ethernet cable. PoE is used where DC power is not available and USB unsuitable.

Power can be supplied at the end of a network span or somewhere in the middle.

PoE switches supply power at the end of a span. PoE injectors supply power

somewhere between the PoE switch and the powered device. They inject power

and do not affect the data.

The PoE is shown in the following figure:
