You guys should really not even try powering up one of these beasts without opening up the box and reseating all cards and connectors. Some things are just bound to shake loose after traveling halfway around the world, no matter how great the QC or packing. Applying power to a system with loose boards and/or cables can cause shorts that may blow out cards or the power supply. You should also tighten up all screws and make sure loose hardware hasn't fallen onto (or into) any electronics. The S1 is/was so successful powering up because of its simplicity, everything is screwed together except for three small ribbon cables.
Design flaw. There should be a bracket holding the boards in place, especially for something you're going to ship by design.
Nevertheless what you say is true.
Multiple design flaws and seemingly non-existent QC. Pretty sketchy/clownish effort overall (did you see the 'machining' of the heat sinks!?). Bitmain isn't alone: the dragon miner I opened yesterday had its own share of ridiculous issues.
tbh, i'm not too worried about it. it's their first go around at doing a design like this and shipping it halfway around the globe. A bit of tweaking here and there I don't mind. This isn't something that will really need to be around for more than several months.
Personally I'm tired of fixing half-assed hw/fw - and not getting any support from the manufacturers in doing so (no source, no schematics, no eng contacts).
