Is it me or does that one blade in your image not have any sort of heat sink on it ?
Also, still looking for five (5) S2 coupons that don't expire for at least a week or longer, just PM me with what you got... will make a sum total 0.4 donation for all.
Edit: My BitMain name is the same as my name here, MoreBloodWine
You are right ,the main controller card have no heat sink. 5 Asic cards above, 5 Asic cards below it have heat sink.

I would like to order up to 5 units. Looking for coupons to buy first! Please PM if you would like to sell. Bitmain username for donating coupons is DotSauce.
Anyone have an idea or guess when S2 upgrade package will be announced / shipped? I'm guessing it will be a couple replacement hashboards?

1. don't try immediately after it shut down (by itself). Wait 10-20 min. Somehow, this helps. 2. If #1 does not work, try with a different PSU (EVGA1300 was better for some). 3. If shutdowns continue and the temperature in the room is below 35oC (it does shut down above 35oC), then remove one hashing board and hash with nine. 4. sd card preparation instruction is on page 86

After having no setup issues and running great for the last couple of weeks, I woke up this morning to find my batch 1 AntMiner S2 not hashing, fans going full speed, panel dim and the red light solid. Recalling that others here have had the same issue, I went back and skimmed over the previous posts and found that the likely issue was probably a corrupt SD card. That was indeed the case, as I am now back up and running, and I figure the problem started when a brief power outage occurred here this morning. Thought I would briefly summarize what I did to recover, which may be of special interest to those folks using a Mac to write to their SD cards: - ran to the store and bought a 4gb Sandisk microSD card. They didn't have any class 10 cards, only class 4, but it seems to work (ordered a couple class 10s from Amazon for backup). - Downloaded onto my MacBook the latest firmware from the bitmaintech website, as well as the SD card image from https://dl.dropboxusercontent.com/u/16075357/bitmain.img.zip (thanks 1l1l11ll1l) - put the new microSD card in the adapter, shoved it into my MacBook, read through the guide at http://elinux.org/RPi_Easy_SD_Card_Setup, and then ran these commands in Terminal: cd Desktop (my bitmain.img was on the desktop) diskutil list (to find the disk name of SD card, mine was disk2, so replace disk2 below with what yours is) diskutil unmountDisk /dev/disk2 sudo dd bs=1m if=bitmain.img of=/dev/disk2 (this took 30 minutes to complete) - once SD card was ready, I opened up the AntMiner, pulled out the BeagleBone card, swapped SD cards and reassembled - powered up, and it started hashing again. Connected to the miner from the browser, uploaded the latest firmware, changed to point to my pool, and everything was golden. Much thanks to all of previous posters that talked about this issue, as your help got me back up in hours as opposed to days.

Sometimes the LCD does not work, but the S2 hashboards will still work fine. If it is running, try connecting to it at 192.168.1.99 and see if it is working. I have two units with no working LCD but they are running fine.

Center blade is not a miner. It's the controller or something. There are 5 hashing blades on each side of it.

We have received an S2 Antminer yesterday. The 1000W Enermax PSU of Antminer was not working at all from the start! So we have no way just to replace it. We have replaced it with an EVGA G2 1000W 80 Plus Gold PSU and now the unit running! Here is the pics: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fforgeco.in%2Fimages%2Fpowerreplace1.jpg&t=665&c=57U9d7MsOFF0IA) ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fforgeco.in%2Fimages%2Fpowerreplace2.jpg&t=665&c=IIC7L-EvZuRgiw) I hope that Bitmain cover our costs and the headaches to find the problem!
