  • Which network cables power the PoE switch

    Which network cables power the PoE switch

    A PoE or PoE+ switch sends both data and power through an Ethernet cable such as Cat5e or Cat6. In this configuration, an Ethernet connection includes Power over Ethernet (PoE) (gray cable looping below), and a PoE splitter provides a separate data cable (gray, looping above) and power cable (black, also looping above) for a wireless access point. Power is injected using one pair of wires to carry the positive current (“plus”), and a second pair to carry the negative (“minus”). Instead of running a separate power line to each device, PoE lets the Ethernet cable (usually a Cat5e or Cat6 cable) carry both the network connection and. For networked devices, PoE eliminates the need for traditional alternating current (AC) power circuits and outlets. This means PoE can be installed without risk to.
