ANTMINER S2 Discussion and Support Thread

[tranzsport]

Dumb UPS. Last night routed my package from Alaska to Kentucky and I am in California. Delayed 1 extra day. Was ready to un-box today.

I live in Alaska and they arrive in Anchorage from China in the afternoon, then get sent to California, and back to Anchorage overnight, to be delivered to me the next day.  I just received notification that there's been a flight delay and my latest S1 is in Anchorage and will be delayed.  And I'm thinking why not just send it down here then and have it arrive tomorrow as expected, can't you read the address?

I have the exact same issue as you pal.. the bad thing is this would delay the original Friday delivery til Monday and not Saturday since UPS Worldwide Express Saver doesnt have a Saturday delivery.
I think the reason why they go to CA is for customs release.. UPS hub at Anchorage doesn't have customs release.. just a guess

/etc/init.d/cgminer.sh is hardcoded to ping 192.168.1.1 for some reason.  I changed that to my gateway ip.

I tried entering a static IP to see if that made any difference, it didn't.  Changing the IP in cgminer.sh does get it hashing.  

I was getting about 90% hashrate so I opened it up and realized one card wasn't hashing, tried reseating it and then switching it with another--the issue followed the port and not the card.  Finally, I reseated everything and it's all working.  The other issue I had was that the ethernet cable wasn't fully connected to the port inside.  Lots of random little issues!

Now I am also getting the hashing for a while then beeping.

what did you guys do who received the wrong plug? just use a different standard one in its place?

The one I got is for the UK i think and I a in the US.

thanks!

Did anyone else have this issue in the USA? ok to use standard PSU plug?

thanks!

Wish I had one to help, but with guys like atadro buying 6 there weren't many to go around.  Being first has its drawbacks, good luck guys, I hope you get it figured out.

You can say that again.  Both of my 2 units are totally fubar'd.  Unit 1 had the Raspberry Pi board popped out of the bus, and several cards were out of their slots, but even after re-seating it (and checking all connections), I can't get any connection to the unit.  The LCD display lights up but there is nothing displayed, and the green light on the LCD never comes on.  The ethernet port seems connected to the switch (switch shows active connection), but 192.168.1.99 cannot be accessed at all via SSH or http or even ping.  Dead for all intents and purposes as far as I can tell.

Unit 2 was a great example of total lack of QC (or else the unit was put in a washing machine and run through the "shake it up and spin" cycle).  Check out the pics below.  I haven't even tried to repair, as the bus connections are so bad (and many are loose) that it is impossible to seat all the boards and even if I could seat them, they would be under great strain.  I can't believe they shipped something like this and I can't believe that shipping damage would be to blame for this one.

It could be shipping damage, except that the boxes arrived in perfect condition, not a scratch or ding to indicate rough handling.

I guess I will find out soon enough whether bitmaintech stands behind its products or not.

Yup, same issues here, all 3 machines the controller was completely unseated, two had the ribbon cable pulled out, one had the ethernet disconnected. And one has a bad power supply.

Since a few people have said 'RPi' ... I'll point out (though it's obvous from the last set of pictures) it's a Beagle Bone Black.

So there's no real "Reset" as such.
In the same way as your desktop doesn't have a "Reset", just a reboot.

Though you can pull out the SD and reflash it.

Edit: 2 things:

1) So it would be advisable to make a copy of the SD now and then if you need to reflash it later you can.

2) If someone could compress that and upload it somewhere would be good.
We've still not got any cgminer source code anywhere so I'd like to look around and see if they put it on there.

That is fucked up, hope it works out.

Had the wrong tracking number at first, but now have the correct one and my 1 S2 will be here tomorrow (likely late afternoon) due to a UPS error that got it rescheduled for the next day.

Guess the first thing I do will be opening and checking the insides.

[jamesg]

Looks like the driver for the S2 is doing some not so fun stuff including:

• Not reporting the "Best Share"
• Allowing bad work to be submitted resulting in a 50% rejected rate

Even with the reject rate, the miner seems to be running 1000Gh/s.

I got my S2 today.  

However, the display does not light up.  Although the fans do turn on and I can see red lights inside it.  

Also, the Ethernet is not detected by my router.

So the consensus is that I should open it up and see if anything needs to be reseated?  Will this void the warranty?

Thanks!

Check that all cards and cables are seated properly.

Idle 1TH/s or risk voiding warranty ... tough choice

Yikes.  i have 3 arriving tomorrow.  So, is it just squeaky wheels who are posting slaughterhouse pictures of their s2's, or are almost ALL of them in some state of being smashed to bits upon arrival.

I don't have a sense for how many S2's were in batch 1, but i assume most people receiving them today also are at least readers of this thread.  So can some people who received their's in good, working order please post to put my mind at ease!

lets hear from some more people with working S2's!

who's got the most so far?  sure like to hear from someone with 10+.

not gonna sleep well tonight...

3 today, all of which would not power on out of the box, had to open it up and put it back together. 4 arrive tomorrow and 5 more when UPS decides that the value to weight ratio is okay. Sitting in China right now.

[jjiimm_64]

I had 2, had to re seat the boards...

definitely open the case and seat all the boards at minimum.

[seriouscoin]

good to see all the old vets are back into mining



Sadly i didnt have a chance to get some S2

[bcollan]

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.

Can someone with a known good unit grab an image of their SD card and post it up to download?

wow, I didn't even notice that it had an SD card in it. I'm used to the KNC units that store everything on the BBB's memory, no SD card needed. If no one else gets to it, I'll do it tomorrow

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.
