it will not login via ssh with putty and tells me that the password i am using username: root password: root is not working, so i cannot even change pools.
Password is "root" via web and "admin" via ssh. Why it is different on these I have no idea.

Password is "root" via web and "admin" via ssh. Why it is different on these I have no idea.
Fuck, the case screws won't come off... anyone else run into this?
yep had to drill mine out
Antminer S2 turned up today, it was in horrible condition, cards loose everywhere, thermal paste everywhere, pci slots all bent to shit, after an hour and a half or so of fiddling (2 screws were stripped and needed to be drilled out) i managed to get it back together, then i had a problem with the screen, played around some more and got that working.
PROBLEM!
Its turning on and mining (all cards are flashing, hash rate on screen etc) but it will not allow me to access the settings and displays a "404 not found" error and on top of that it will not login via ssh with putty and tells me that the password i am using username: root password: root is not working, so i cannot even change pools.
Bitmain shipped me a unit that is basically mining for them!
Can someone please help?

UPS just delivered three S2 units instead of the expected two, my mind was working overtime thinking that I had lucked out but noticed the address on the third unit was not me :-( just caught the guy as he was leaving, returned the third unit. Would have been nice.
i think bitmain owes you a shirt and the unlucky now lucky again miner who must live in your neck of the woods owes you AT LEAST a beer/coffee

I replaced both stock SD cards with new ones. The stock were no-name cards, 2gigs. I replaced them with brand name high speed ones from my GoPro camera.
I will watch to see if they suffer from the same corruption problem or not, but i really don't feel like trying to crash it on purpose at this point.

Format the card and image it, try to boot, if it won't boot take a few asic cards out so you can read teh BBB and eject the sd card while the unit is on, then put it back in, you'll see the ethernet lights cycle, I've had that make mine turn on before.
In other news, I did have a bad BBB that wouldn't write to the SD card. I replaced it with a factory BBB, that's what my machine is using now
Ahhhh, now THAT was some f'ing good advice! thanks mate - you're the best. followed these steps and got each one working with 8 boards. Sweated like a blackjack player holding 17 for a while, wondering if i should stick with what works or risk it and try adding the other two boards.
I chose to try something new - i ejected the SD card while it was running. Left it like this for about 5 minutes. it kept mining! i then powered it off, added the two boards, popped the card back in and turned it on. magically, it booted it up just fine!
So, until i figure out something better, this is my step-by-step to deal with the corrupt SD card problem:
shut off
remove 2 asic boards and sd card
reimage sd card via laptop
boot up with 2 cards missing, pop card in and out until it boots (you can tell when the blue lights on the BBB card near the ethernet card light up)
when it's running, pop out SD card, power off, then add 2 boards, pop card back in and hope for the best.
Buy new SD cards
What kind of SD card should I buy? Regular SD or micro SD? CLASS 10 microSD
I forgot to ask: what size? Is 2 GB enough?

Buy new SD cards
What kind of SD card should I buy? Regular SD or micro SD? So i've had my three batch 1 S2's running for over a week now, and have some observations:
Stable.
when they run, they run. have not had the need to babysit them.
corrupt SD cards.
twice now, i've gotten corruption on the SD card on one machine or another. If there's a power cut, i cross my fingers and hope for the best. chances are, at least one machine will need it's SD card removed and re-imaged. Big thanks to the guy who posted a link in this thread to a copy of his SD card. Although Bitmaintech has now posted updates to the firmware, they are in the format needed to update via the web gui - not directly image the SD card.
this problem is particularly concerning as there is no "shutdown" option in the GUI or button on the case. just the power switch. So each time you shut it off, you have a 50/50 change of buggering the software.... yikes.
can't power on.
This problem is unrelated to the software issue described above. for some reason, there's some kind built-in protection in the power supply that prevents it from being turned off and on again quickly. i guess this is a good thing, except it give the impression that the thing is dead until you leave it be for at least 15 minutes between powering off and on again. Have not found any work-around. Now that i've learned this, i know to expect it, but to the uninitiated it is a temporarily heartbreaker.
I will have to look for this when I start testing the 1 bad PSU that came with my S2 Stable.

more importantly, what's it hashing at the Pool??
15 minute averages:
538.6 GH/s on acct #1
541.9 GH/s on acct #2
OC'd @ 200 - ASIC Freq
OC'd @ 225 ASIC Freq
Replaced PSU w/ EVGA 1300.
Hardware errors are much higher! But it is doing short of 2000 WU more per minute @ 225.

Thanks, i'll try that tonight.
Any link from where i can order a spare BBB? I've found a few online but they all say out of stock.
On another note, i have noticed that when i power off the machine, it goes off then briefly back on for just a moment. Happens every time i turn it off. Perhaps this little blip is causing the problem.
Awesome attitude shit-cunt!
Is that how your parents taught you to talk to people?
Either answer the question posed or keep your shit to yourself, its rare that anyone wishes to be abused by anonfags over some weak BS.
And by the way, i dont open my mouth to type (or think, or read, or breath) - i know some folks who do, obviously you're one of those!

As if you're one to talk about attitude and politeness when talking to others. On another note, who gives a shit, quit cluttering the thread.
Haha, fair point.
But fk you too!
i wont be abused by some know-nothing-know-it-all mouth breather without fighting my corner.
the guy was asking for rhetorical advice/hopes for future upgrade boards and all he got was 'know-nothing-know-it-all mouth breather' BullShit...
Should we allow these muppets to ruin every thread they think is theirs?
Probably not, eh...
@ sbfree - What are your ambient temps?
The PSU shut down after 8hrs or so....I removed in put in a 1200W temp PSU....checked the bad PSU would power up, but now that its cooled it powers up.
Interesting. Max temp is 58c ? 2 of 3 S2's always shut off after less than 3 hours. The temperature is always between 53 - 59, but one is stable. What is the probability of 2 bad PSU's being sent to me.
I will sit and watch them until they shut off today.
Sigh. My unit still not arrived as UPS keeps messing up. Now they're still processing customs (5 days) even though they've assured me everything is fine.
I've been looking into the SD corruption issue and it does appear to be some kind of hardware problem with the beagle bone and possibly certain types of SD cards.
It does not appear to be filesystem corruption. As far as I can tell there is nothing in the image that is writing to the card other than config changes, and the filesystem is mounted sync so these should always happen right away when you make the change.
I think it will be necessary to have extra SD cards on hand for repairs. Maybe someone will figure out a make and model of SD card that doesn't fail this way.

My S2 was running fine overnight since last evening. Suddenly stopped hashing (based on pool stats).
Will have to investigate when I come back from work.
Anyone else had a similar experience?

Does it show anything on the webui? Do you have a failover pool selected and does that report anything.
What does the LCD say....
You have to give us a little more info to help.....
