ANTMINER S2 Discussion and Support Thread

[Gogreen]

Thinking about the s2 kit but prefer s1 version 2
Anyone bought the s2 kit please show us some photo.

Oh crap, my batch 2 AntMiner S2 stopped working today, after 3 months of solid service.

We had a power outage, and after the power came back on the S2 was "dead". It wouldn't power on at all. I replaced the Enermax 1000W PSU with a Corsair AX1200i and the unit now powers up, but nothing shows on the LED screen and the unit doesn't register on the network. I know what the MAC address of the unit is and it doesn't show up on the network. I have tried two different micro-SD cards, neither of them work.

Not happy.  Sent an email to Bitmain, hopefully they can help me out.

You have a scrambled SD card. Search the forum for a solution. It's a very common problem.

Does replacing the card with a better one help it survive outages?

I'm not 100% sure if it helps survive outages, but the card supplied probably won't last long... mine gave up after a couple of months. A better card might still get corrupted in a power outage, but at least it won't become completely unreadable. It's best to at least have one spare imaged card laying around.

Hello All,

Anyone have two S2 coupons they don’t plan to use? Looking for two, thanks.

[fhh]

Do they use standard Beaglebone Blacks? Perhaps you could try replacing that. I stocked up on spare WR703N's and rPi's for my (former) Avalons and BitFury rigs and had to replace a few over time. Maybe I should buy some BB's too.

No they use extremly reduced BBBs. there are no ports on it. only ETH

BUT a standard BBB works fine.
I replaced one when the SD was corrupted and I also couldn't get the S2 back to work with a new card.
The new card in my original BBB then worked. And after saving all changes I also got it working in the S2 BBB.
I don't know why?!?!?

Anyone got any spare coupons going ? ?

Magic, never tell the customer however if you work in support, the secret must be protected.

Yes, without a doubt! Buy a Class 10 Micro SD card (or two), you won't be disappointed. I had similar problems with the SD cards on my Bitfury rigs. Some high-quality Patriot brand cards solved the issue completely.

Which holidays-country specific? maybe they are fixing something? price difference is mostly because of 10% BTC price rebound and you never know which way this will turn in the future. Having said that-I get your point.

If you haven't purchased from BITMAIN before then you may not realise that its common for you to recieve your parcel before they even have a chance to update their web site to say its shipped.

Bear in mind that 13:58 your time might be the middle of the night China time (unless of course you are in China) then you can give them a little leeway.

Have you tried emailing them before throwing your toys out of the pram here? (Bear in mind its the middle of the night there now)
