7.2 PoE (Power over Ethernet)
PoE stands for Power over Ethernet and describes a practice for using a single CAT5e (or higher) to incorporate both
power and data in the single cable.
Few advantages:
•
Easy setup
•
Single cable run up to 100 m
•
Using PoE doesn’t require certified electrician as the power loads are small
•
Existing network infrastructure can be used
7.2.1 Definitions
PD
(Powered device) – device that is connected to PSE and thus is powered by it.
PSE
(Power Sourcing Equipment) – device that provides power to PD, can be a network switch or injector.
PSE Types
In our case, we consider only following two types of PSE devices.
•
PoE Switch: a switch that offers possibility to power PD. Switches use PoE classification.
•
PoE Injector: typically a single port device for powering 1 PD. These exist with classification (active) or without
(passive). Neutrik's NPS-30W is a passive PoE injector.
The term class refers to a maximal power output (see table below).
