I now now have 2 power supplys connected - the blades connected are no longer flashing red lights - so that problem is fixed
But still no data from the laptop port
I have done everything you have said but that port is not sending anything to 3 different coumputers that i have tried. (2 different laptops and my desktop)
I have tries static ip, the ip's and gateways you specified. I have tried so many configurations i am sure it must be something else.
Perhaps if a make a small video showing exactly what i am doing would you have a look at it Tornsten.
