ANTMINER S2 Discussion and Support Thread

what is default IP as shipped?

same as the S1 - 192.168.1.99

[klondike_bar]

i am certainly not as impressed as giga with my first shipment.  none of the 6 hashed out of the box and only 1 could i even connect to the mgmt interface.  prolly gonna be a long night of troubleshooting.  each one of my 50+ S1's hashed out of the box - bring back the S1's...........

sounds like some sort of general network issue - you sure they are on the right IP subnet?

How did you rack mount the ant minter s1's??

Three ants per 22" shelf with power supplies double-sided-tapped to the back of the shelf.

We opened over 1,000 boxes to get our 540 ants setup.

Would love to see a photo or video of the rig - sounds insane setup!!

Well done

Just opened up mine.... nearly every board inside had been knocked off the motherboard pci connectors and had come out of the slide-in slots..

Cannot open a webpage at 192.168.1.99..

continuing surgery..

How do you get it to start mining? I had to make sure all the cards were plugged in and then it would boot. But now I've set up the network, can access the administration page, and entered in all my information, but it doesn't want to start?

same here..

[phobus]

can't ssh in either.  the administration screen has no entry for cgminer version.

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.

ssh login is root/admin

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

machine starts to mine for a minute, then shuts down and starts beeping

continuing surgery...

[abracadabra]

well.. with the 192.168.1.1 line in /etc/init.d/cgminer.sh fixed
doing a:

/etc/init.d/cgminer.sh start

gets me mining...

still no display tho..  I'm thinking one of the other scripts needs to run to update the display..

They used to have a limit on their S1's.  It kind of irks me they don't have any limits on the S2.  Probably because of the turbulent ride BTC has been having lately, they couldn't afford to stick to ideals over profit margins this time around.  can't say I blame them much, either...

That said, I have 1 S2 Batch 2 coming soon, so I too would like to know some of the questions others have been asking:

1) How loud is it?
2) What were the kinks, if any that faced in setting it up
3) Does it make the room an oven?

Mine is going out in a shed with half assed temp controls and airflow, so I'm curious what sort of accomodations I'll have to make.  Drill another vent in the wall and add a giant fan on it, perhaps?

[phobus]

thanks! editing that script did it for me... it seems to overwrite it on every reboot though    i'll have to look for where thats happening.

thanks a bunch.  that got my first one hashing away.  that change plus reseating all boards and cables is prolly required for most to get them running.

number 3 is entirely relative. its 1000W of heat no matter what. If 3x 360W antminer S1 was making it an oven, so will this.

Did either of you guys get the display working?

Mine is dead :/

[phobus]

Mine is dead :/

Yeah, mine worked after I reseated the cpu board.

Well.. mine is mining.. just no display... I'd assume that if the cpu board is not seated, I wouldn't get any hashing at all..

Hmmm, Well I found the overclocking settings.

Heh.. I wouldn't try without making sure you got more headroom on your PSU.  I'm thinking a 2KW server power supply.
and make sure you got plenty of cool ambient air going in.. cause it's going to be toasty coming out..

Looks like they are running them at 196.

Is there any CE certificate link for Antminer S2? It may be very badly needed in some EU regimes.
