What is Power over Ethernet (PoE)?

Power over Ethernet (PoE) is a way of allowing a single Ethernet cable to provide not only communication, as it traditionally has, but also power to devices that are on the local network. This leads to cost efficiency and simplicity with installation since multiple cables do not need to be pulled to devices within the space. 

What is the difference between PoE and PoE+ ?

  • PoE+ delivers a greater amount of power than PoE
    • PoE (IEEE 802.3af-2003):  15.4 watts 
    • PoE+ (IEEE 802.3at-2009): 25.5 watts 

What devices provide PoE power?

  • PoE Network Switch:  A PoE switch is simply a network switch that outputs power and data directly from its ports. 
  • PoE Injector:  A PoE injector is a device that injects PoE power down the line for a device. In other words, cabling is run from a non-PoE switch or router out to a device that requires PoE power. The injector takes the data-only cable in and puts out data and power from an output port on the injector. 

What Lutron Products utilize PoE?

  • RadioRA3 Processor:  The processor can be powered by either PoE or PoE+ IEEE compliant network switches or injectors.  A PoE power injector is included with the RadioRA 3 processor when you purchase it as part of the RR-PROC3-KIT model number. Lutron also sells a PoE injector kit that can be purchased separately, model L-POEI-BL
