Got a batch 2 S4 delivered today, and it killed my batch 1 S4 (no, not really but read on..)

So my batch 2 unit wouldn't work out of the box. The display was showing the IP as 127.0.0.1. After a bit of messing around, I figured the SD card was to blame and that a reflash was in order. Since bitmain doesn't offer a full image to download (why don't you, bitmain?), I had to power down my batch 1 S4, pull it's SD card, create an image from it, and flash that image to the new S4's card. Once that was done, the new batch 2 S4 worked as it should. I'm not sure why it didn't work in the first place, since bitmain had obviously tested it judging by the accumulated (very little) dust in the miner.

Now, for my B1 S4... About 30 seconds after the fans calmed down from their initial spin-up, I was treated to a smoke show like to other. A thick stream of Magic Smoke plumed out of the B1 S4's PSU for a good 10 seconds, before going out with an extremely LOUD pop. That loud pop was a short bad enough to trip the 30A 240V breaker that miner was connected to.

To add insult to injury, the event seems to have killed the on-board NIC on a PC that was connected to the same circuit, so that is also out of commission for now.

Alas, my dreams of hashing at 4TH/s went up in a plume of Magic Smoke. Hopefully bitmain will get a new PSU out to me soon, but I'm doubtful. I contacted them about replacing my PSU the day the offered replacements, but I haven't gotten an email back yet. Has anyone received their new PSU yet?

Fortunately I had another S4 to get an image from, if anyone runs into the same issue let me know and I'll upload the image.
