Mine "play dead" after power outage too.
But come to life, after I pull the U-shaped wire off the ATX plug for a minute or two.

Oh thanks for the tip! I will try this when I get home.. hopefully that is all it is
Is there a consensus on the best replacement PSU for the S2? BOTH of mine conked out last night after a power outage.
I was thinking something along the lines of a Corsair AX1200...

Better go for the EVGA G2 1300watt.
It is cheaper and all miners from different manufacturers also like the EVGA G2 1300 watt.
I replace the PSU's of Dragon 1T miners with EVGA G2 what I have left over from powering antminers S1 before and the Dragons loved them.

Dear Community,
Our truly apologies for the mis-understanding reported in this Support Thread. We are very willing to share the cgminer code to the Community.
Just reviewed our internal resource again, there is a little mis-communicaton between Customer Service Team and R&D Department. We thought this task was done 3 weeks ago..
However, R&D Department is repacking the cgminer code and will upload it to GitHub.com in 3 hours.
Any advice from the Community and Global Customers is appreciated, feel free to contact us via PM or [email protected].
Thank you!

Cgminer 3.12.0 has been uploaded, https://github.com/bitmaintech/cgminer. The latest version will be updated in 2 weeks.
A belated thank you Bitmain - but as mentioned, uploading the code using outdated software with huge security holes is not the wisest solution. Please ensure that all repos (S1, S2, & S3(+)) contain the latest cgminer software that fix the security vulnerabilities - this is very important for both the miner & the network!
Thank you for listening to the community.
I'm copying this from the Bitmain S3 discussion thread in the hope that Bitmain will do the right thing, abide by the law & respect ckolivas request to release their code as stipulated by the Open Source License Agreement:
Exactly. I don't understand why they don't work more closely with the cgminer devs - using such an old miner for this equipment is false economy. There have been many improvements & optimixations since this cgminer release, not to mention a very important fix for work redirection by a third party.
Can we just SSH in to it and compile CGMiner to a newer version ?
One would assume that we have access to their modified code and driver for cgminer which the cgminer license stipulates, however they have ignored our requests for making that code available. I am considering what direction to take now about that license violation.
Indeed, I saw your post requesting access to the code - ignoring it seems a very strange course of action by Bitmain, especially since agreeing & cooperating would not only benefit everyone - but would also stay within the legally binding license terms.......
I hope they realize their error & do the right thing - as well as live up to their claim of supporting the Bitcoin community.
@ckolivas: Is there anything we, the community, can do to help? Maybe if we all started mailing them they will take notice?
Hmmmm.......Sorry to quote myself, but the more I think about this - the more it doesn't make any sense. in fact, it smells.
Apart from the obvious legal obligations pointed out by ckolivas, one of the hardest working & well respected Bitcoin community members there is, I find myself wondering why on earth Bitmain won't release their code - are they trying to hide something? I mean, the third party redirect fix was a very important update - why on earth would Bitmain not want to implement it? There are also a multitude of other fixes & improvements which Kano (where is he by the way?) listed in a previous post regarding the S2, but are still relevent:
By not cooperating with the cgminer devs request to release the code as they are legally bound to do - and not updating cgminer to incorporate the very important security fixes, Bitmain are not only breaking the law - but they are also arousing suspicion amongst the Bitcoin community as to why they are refusing to do so. For a company that claims to respect & care deeply for the Bitcoin community, this makes no sense to me whatsoever.
Before anyone starts breaking my balls accusing me of stirring things up trying to discredit Bitmain - I am a customer who has Bitmain hardware & am quite happy with it. I am merely pointing out the legally binding obligations Bitmain are ignoring, as well as trying to highlight the contempt that Bitmain are showing towards ckolivas & kano - without who, mining & Bitcoin would not be what it is today. We, as a community owe it to the cgminer devs to make sure that all hardware manufacturers respect their requests to release their code as stated in the open source license agreement. If they refuse - we should all be concerned as to the reasons why.
Sorry to ramble, but I'm a great believer in Open Source & what the cgminer devs have done, and continue to do. We owe them
I do wish the BITMAIN would publish the device driver details so that a current version of cgminer could be attained. I know at least 2 releases in 4 had notes about queue improvements and one at least specifically stated it generated work much faster. Also one of the last 3's had an improvement about how work was loaded into devices. I know for sure 3.12 is very old and I am positive that many work generation improvements have been added since then.

Because:
1) The version in there throws away valid blocks on p2pool
2) The version in there doesn't block the recent stratum redirect problem
3) The version in there passes all shares to the pool even if they are below target (I'm sure pools must hate the S2 due to the major increase in CPU requirements at the pool)
4) The version in there has the API set to W:0/0 so anyone with network access can change your settings/pool/username (and the web page doesn't let you fix that)
5) The version in there has a modified API with different field names to the standard API so anyone using other software that reads the API must get that software changed (or use a proper API version of cgminer in the S2
)

If you have to buy two kits that's .8 btc where you might only get .1 ROI...Hope they can do better for the S2 upgrade kit!
Wow success 
Bitmain released upgrade for S1.
Who knows they might do also for S2 soon.
The price is 0.46 BTC.
It's a cool kit but VERY EXPENSIVE. I did some calculations at Bitcoin Wisdom and it will most likely make a tiny, tiny profit of 0.1 BTC or so.
And this is without taking into consideration that the S1 anyway would generate more than that if I leave it running underclocked and undervolted.
Will YOU buy the S1 Upgrade Kit? If so, what is your reasoning?
And you have to buy at least 2 kits

I must say that it does seem like the S2's were rushed out to use up the old chips while they were already working on the S3, hence the stability issues that will probably never be addressed because now there's a better product out using newer chips.
The one thing that is bothering me the most is that Bitmain is doing their own thing with CGMiner and releases unstable hacked versions on their hardware with no support until Kano takes a look at it. It seems they are having the same issues with the S3 now and CK is getting a little annoyed with them.
I used to hold Bitmain in high esteem, but now I'm distancing myself from the idea that Bitmain is a professional business.

+1000
Everything changed from that meeting
With new friends:
Yingfei Li, Bitmain
Xiang Liao ("Jack"), lightningasic CEO
Alex Kampl, Allied Control
Not in the picture:
David Fan, Bitquan ("AM") General Manager
Rock Xie and Alex Lam of RockMiner
Had a great time.

Small debt, pictures with Rock Xie of RockMiner:
Coincident
I say NO, that is because THEY have a deal Bitmain joined to "The Club" and can't decide by his own anymore
THEY probably have time schedules already arranged.
DECENTRALIZATION !!!

Right, guys let's be honest a lot of us don't want admit (that's embarrassing I know) but Spondoolies, Bitmain and others ripped us of.
I know this is Wild West Crypto World still and THEY know they can afford it but how long for yet ?
Someone MUST stop it.
My theory is THEY had those chips long, long time ago. THEY start selling when chips become not that profitable any-more otherwise why they selling ? THEY got huge bitcoin farms, well Bitmain has.
THEY probably already invented and mining with new ones.
Really guys I can not stand it, THEY not support Bitcoin network, they think just about their profits but what nasty way THEY do business ??
Honest business partner should think about future, before they start selling S3 they should start selling upgrade hasboards for S2.
If someone ask me, BITCOIN MINER never again

Yet YOU willingly gave them money. They're a business, what do you expect? I guess in reality none of them should retail sell HW, then people like YOU won't get sucked into the hype and buy HW without undersanding the business you're entering.
Sorry I called it business no that is not a business that is just a scam
dropt and you probably involved in resell of that shit if yes good for you at least you will be better of than we, but make sure not to use PayPal otherwise people will claim refunds

A short good news for the S2 buyer is that we will let the S2 to upgrade to 1.8TH/s or 2TH/s at very low cost which you can only image now in the August or September.
Well, are there any details (at least roughly) about this upgrade? What would it be and what will be the price?roughly - too little, too late & too expensive
+1
Sorry I lost so much on S2 that for me that is nothing.
Is Bitmaintech still waiting
Why ? What for ?
Don't know why everyone keep quiet ?
That is the biggest scam ever !
Imagine how many people lost their money that way.
Bitmaintech policy before meeting witch Spondoolies was no pre-ordes now everything changed they know how to deal with idiots as we
Bitmain what you waiting for !
Yea if that upgrade doesn't come through and isn't affordable a lotta people will get burnt on the s2. I might get 4-5k outta my 8.5k investment at this point.

I am having some trouble with an S2 unit that I have had running. It has been running perfectly at 1 TH/s since I got it, but after some installation of S3's last night, it is now showing problems.
The LCD on the unit says that it is hashing at 1 TH/s and it looks to be OK inside the unit. Everything is flashing normally and looking OK, but the pool is only showing about 100 GH/s hitting it from the unit. Does anyone know why the two might be showing this discrepancy?

Interesting, does S3 show 1300GH instead? Are both units on the same ethernet hub or connected independently?
I had a freak occurrence when I unplugged S2 that was on the independent power strip and S3 that was nearby (and on a DIFFERENT power strip) switched off, then back on.
This is weird, I know.
I think that this is because S3 has some wi-fi capability which might have some interaction with the router or they somehow had some interaction through the ethernet hub. Anyway, it was spooky, but I double checked the fact that the units were on different power strips.
Does that 900 mH go anywhere where you can detect it or is it just gone?
I haven't been able to find it at all. Everything else connected to my pool is accounted for as each unit has a different worker name and everything else it running fine. (Besides one pesky S3 that I will have to spend some time trying to get running properly tonight). I can't imagine that one is causing problems for the other as there are 10 S3's, 5 or so S1's and 2 S2's running in parallel down there and this is the only issue.
Perhaps, with a last miner you exceeded your downstream internet provider speed as you have so many. I assume that they are all on the same router.
Are they all on one hub or several? If several, maybe try mixing them up differently.
