Hiya, I forgot to tell everyone what my power config is

I have separate power adapters for each unit, So a quick swop around eliminated this problem, All my adapters work fine in the working lancelot's.
Did not know about the fan? I tried this and it did not work anyway, But worth a try.
See from my pics (on Flickr are at full resolution) if any of the dipswitches are in the wrong position, maybe they have been moved during the assembly? You have 2 groups of 4 (but are covered by a thin layer of transparent plastic, so it's very difficult to touch tem), and 4 on the top side, nearby the fan connector.
