Introduction:
To achieve best performance of a Wireless LAN, the location of Access Point (AP) must be carefully chosen. In most cases, finding a power supply for AP is a common obstacle. Power over Ethernet (POE) technology provides the ideal power solutiom to help overcome these obstacles.

In Ethernet, four pairs of C5 or C5E twisted pairs are used as the medium for transmission. The actual data transmission, however, only takes up tow pairs of wires (pairs 1-2 and 3-6). POE technology utilizes the remaining pairs(pairs 4-5 and 7-8)to conduct electricitr.

Function:
Power Sourcing Equipment(PSE)transforms AC to DC. It has a maximum outout power of 30w, fluctuation of 60mV with a tolerance of ±3%. When it overflows, overloads, short-circuits, or overheats, the PSE automatically truns off the power , and restarts after these problems are removed.

PSE applies single chip control management and uses compatible programs. Technical parameters aer as follows:
1) When PSE detects that it connects to a device which uses on electricity, the power supply will be turmed off automatically.

2) PSE monitors circuits status at all times. Once it connects to an electronic device that has a range between 1-30W, it automatically provides electricity to it . When it is lower that 1W, electricity will not be suoolied.

3) PSE protects circuits from problems such as short-circuit, overload, and electricity receiving device damage by turning off the power once a problem occurs. Normal power supply will be resumed once these problens sre eliminated.

4) LED indicators for PSE:
A: LNK(Green): Connection Indicator On => good Off=> on good
B: ACT(Green): Power Indicator On=> good Off=> on good Blind=> currently supplying power
C: ERR(Red): Error Indictor On=>Error Off=> good (Short-circuit, overload, or electricity receiving device damage)
