Decided to take the plunge and order a brand new S9 today and its starting to look like a dud,

Pulled a working PSU from a S7 I had running and plugged it all in, it powered up with fans at full speed, none of the hash boards have lit up and its not coming up on the network.

Does anyone have any idea of a fix or am I going to have to try through Bitmain?

Regards
Alex
