Hello, I have strange problem with my s2. It worked like a charm and then started to make problems... I switched PSU for 1200W FSP and even microSD card with new 4GB Samsung. I tried with all boards and with one board and S2 is still not hashing.
No matter what I do my S2 only spin fans on max rpm and I can not access it via browser.
Any suggestions?

That sounds like a SD card problem... try re-imaging it, or try the old one again...

Then I'd say check all the cables are firmly inserted... if the screen stays blank, then it must the the beagle as you say, or the card. If there was a problem with your network it would still boot up.

I'd noticed you'd upgraded the power supply, so figured it was possibly something that came loose during the process... glad it's working ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Hey guys, I have a quick question regarding the boards in the S2. I have one card that needs to be removed to RMA back to Bitmain, and was hoping someone here has done the math on which card slot the chain #1 card coincides with. Is chain 1 closest to the PSU in the unit, or is it furthest from the PSU?
Cheers.

I believe its the one furthest away as that's always the hottest card.

Yep, it's the furthest card.. the slot numbers are written on the power board. The numbers don't always match the chain number in the gui if a card is missing though, i.e. if one card is missing from slot 4, the gui will show chain#1-9.

I don't think there is a fix for this... perhaps BITMAIN will release an updated firmware soon (hint, hint)... hopefully.

At the risk of sounding like a complete noob... if you can change things like miner configuration and ip address, why not the password, wouldn't that just require an update to the luci interface with the appropriate commands?

Tbh I think this corrupt SD problem is probably more to do with some shoddy programming than anything else. I think there is something writing to the disk the whole time and if not stopped 'gracefully', it corrupts the card. I'm finding that if I eject the card before powering down, I don't have a problem with corruption. I haven't re-imaged a card in a week ![Grin](https://bitcointalk.org/Smileys/default/grin.gif)

I've been troubleshooting a malfunctioning blade and have had the power off and on 20 times or so at this point. Zero problems.
