ANTMINER S2 Discussion and Support Thread

There is one blinking blue LED by the ethernet port cable.

There is a solid green LED on the middle card in the center of the rig.

There is a solid red LED on the middle card in the center of the rig.

There are 2 solid red LEDs on the bott board where all of the other boards plug into. They are between cards 3 and 4 from the top, and 3 and 4 from the bottom.

Some of the cards are piping hot. Some are not.

This is my hash rate

Where is the power going?

[Zelek Uther]

sorry to pass out on you all but i was exhausted.

i said i can ping no problem IE ping with 0% loss = ping is possible

on BBB blue leds flash, red led is solid

on control board2 solid red leds. 1 solid green, and 1 flashing slowly green led.

ive pulled the short 'pigtail' ether cable and connected to the BBB directly....

LCD screen is ok  but the red and green lights to the right side are both off

and the back plane has 2 solid red leds, one on either side.

And STILL - 404 Not Found....

I have started getting the 404 Not Found error too.  I found that this URL works for me (replace with your S2 IP address):
http://192.168.1.99/index.html

[Elyssium]

Nothing.

Whats a BBB?

As far as I can tell, since the boards are hot, its doing SOMETHING. Maybe mining for Bitmaintech??

But no hashrate.

Wow, nice work.  How the hell did you figure that out?  that's great news.
I don't currently have this problem, but it's probably coming, so it's sure nice to have this solution on deck.

If you figure out an explanation, please do share.

[dalenorman2005]

once you get it updated to the current firmware dated april 10, theres a DIAGNOSTICS tab in the Network config that lets you ping, traceroute, and nslookup. 

[dogie]

This is the highest speed I can get.

At least your hardware error rate is zero

Haha. But on a serious note, try it with only one module ? Does the green light  blinks on any of the modules ?

Your network gateway is wrong.

When i hit ping it just says "ping bitmaintech.com"

And nothing else.

Its the same as all my other machines. Is that wrong?

[Elyssium]

I got it working.

No idea how. I changed DNS servers to 8.8.8.8 though. But then it wouldnt work for awhile.

I go afk for a second. Come back 10 minutes later, its working.

[Zelek Uther]

same.

tried with only 1 board in - still 0GH/s

can anyone confirm the RED LED on the BBB is supposed to be lit ?

I finally got mine working... I'm such a nobbin, I assigned an IP address to my S2 which was THE SAME as an existing PC on my network.  I finally found it because I powered down the S2 AND pulled the network plug... but was still able to ping the IP address.  That's when the penny dropped.  Even with the same IP address as another PC, the S2 would mine for a bit, then stop and beep, then start again... so it appeared like an intermittent problem.

I do have a red LED on the BBB, also one on the board that it is attached to - both red LEDs are on constantly (no blinking).

See my reply above - I was assigning my S2 the same IP address as a PC on my network... D'Oh!

I figured out the URL by SSHing onto my S2 (somehow I got on... not sure how with my router in conniptions with an IP address conflict).

I found the directory /www/pages which has the files:
administration.html
cgi-bin
css
dav
images
index.html
js
kernelLog.html
minerConfiguration.html
minerStatus.html
monitor.html
network.html
networkDiagnostics.html
reboot.html
resources
type
upgrade.html

So I tried accessing a page directly, e.g.:
http://192.168.1.99/index.html
http://192.168.1.99/minerConfiguration.html

Any of the above should work

[Elyssium]

glad to see u guys got it sorted, gives me hope!!

changed to a few diff IP addresses and no joy still.

0GH/s

I am sorry. Normally I would be able to help but I just did not do anything meaningful and it started working.

Hostname antMiner
Protocol Static
IP address is unique and open
Netmask is 255.255.255.0
Gateway is 192.168.1.1 which is what I set my modem to.
DNS servers to 8.8.8.8

I flashed to the new firmware

I removed every single card and reseated them

I had one loose ribbon cable. I fixed it.

I powered down and back up a few times.

Good luck.

[Elyssium]

I'll try flashing the firmware though i see it already has the latest version...

can u link it, plz

You can get it here.

https://bitmaintech.com/support.htm

Aaaaaaaaand its dead again.

Power to it went off.

All lights are dark. Screen is dark.

What gives with these things???

You may have tried everything already, but just in case...

Do you already have a device that uses Bitmain's default IP address of 192.168.1.99?

If so, assign it a new IP address, and continue (if not, that's perfect, continue):

1) Download 1l1l11ll1l's S2 SD Card image from here (all credit to 1l1l11ll1l - good chap!):
https://dl.dropboxusercontent.com/u/16075357/bitmain.img.zip

2) Unzip and write the image to a brand new class 10 micro-SD card that is at least 2 GB.  Buy two, just to have a spare.  (FWIW I bought two of these: Apacer Micro SD Card 8 GB Class 10.)

3) Go through all the hassle of putting it into your S2 BBB.

4) See if your machine mines with 1l1l11ll1l's image.  Don't change anything yet.  I found it worked for me.  Obviously we haven't set it up properly for your S2 yet, but at least it will show if a known good image on a fresh SD card works on your machine.  Yes it will be mining for 1l1l11ll1l at this stage, no prob, this is just a short test on a known good image.  

Note that 1l1l11ll1l's image is the latest S2 firmware: "Thu Apr 10 19:08:42 CST 2014" which is what you get if you update with "initramfs.bin.SD-20140410.tar".

5) Once you have it working, set up your miner config and IP address to your preference.

Dogie's comprehensive setup guide now up in super HD!

S2 shuts down, no power.

Check breakers, all are fine.

Toggle switch, no life.

Change plugs, no life

Change circuits, no life.

Change rooms same circuit, now it works.

Go back to original plug, now it works.

What the fuck is wrong with this equipment lol.

[Zelek Uther]

foolish me, i already downlaoded that file from Bitmain/support

and i already updated to 1l1l1l1l1ls image last night

i do have one S1 rig that is on 192.168.1.99 but that shouldnt matter if ive changed the S2 ip to something else..?

It shouldn't matter... but just for the sake of using 1l1l1l1l1ls image untouched why not try changing your S1 to another IP address?

Just trying to eliminate any complications... your S2 should work on 1l1l1l1l1ls image with no changes at all... later we'll need change it so it mines for you, but for now we just need to get your S2 hashing.

If your S2 doesn't work with 1l1l1l1l1ls stock image, then stick with 1l1l1l1l1ls image and start eliminating pieces of hardware one by one... e.g. try it all identical except swap the SD card for another (new) one.  Try it all identical except swap out the PSU for a known good one.  Then try with a new BBB...

AFK now... g'luck!  Hope to see your S2 hashing soon.

[Elyssium]

And now it turned itself off again.

Im sorry Im not sure how much more of this i can take.

Sounds thermal. While you were messing around with things, it cooled off and reset itself.

Switch PSU.

[Elyssium]

Im about to throw this thing out the window honestly.

I have had every problem with this unit. Bad Display, bad screws, bad internal ethernet cable, not hashing for hours, everything covered in spooge, bad PSU.

[pvnamk19]

I am eager for Batch 3 Ant S2 from Bitmain. We all know that Spondoolies offer 1.4 TH/s with 3600$, shipping before May 10th.
It is a tough time for Bitmain to beat competitors!
