IC40 lights are not on. I tested the power center on the AC side. All the way to the PCB I have power. The green LED is not lit. This is the second time the board will have gone bad and they are not giving the boards away, if you know what I mean. Can I just power the IC40 with and converter. It's 400 watts @ 24 VDC. The output to the IC40 is 200 watts, 24 to 39 VDC. Also what is the D- and D+ wires used for? I know they are data wires, but what data. Thanks!
