75 Watts of Power over 4-pair UTP
The GS-5220 LCD series with LCD Touch Screen that features ultra PoE adopts the IEEE 802.3at/af standard. Instead of
delivering power over 2-pair twisted UTP – be it end-span (Pins 1,2,3 and 6) or mid-span (Pins 4,5,7 and 8), they provide the
capability to source up to 75 watts of power by using all the four pairs of standard Cat.5e/6 Ethernet cabling. In the new 4-pair
system, two PSE controllers will be used to power both the data pairs and the spare pairs. They can offer more PoE
applications, such as:
■ PoE PTZ speed dome
■ Any network device that needs higher PoE power to work normally
■ Thin-client
■ AIO (All-in-One) touch PC
■ Remote digital signage display
