If your blades are anything like mine, it will happen again. I agree it sounds like we're having similar issues, as are some others on the forums. Mine will get to 10.7, 11ish for a good couple hours, then switch proxies, and usually sit in the 300mh-2gh range for awhile, then switch and they die off and constantly reboot.

There's something not right in the firmware in my estimation. Sometimes, even on a cold boot, they just don't send packets out, and sometimes they do. Sometimes after not sending packets out for hours, they'll suddenly start. There's clearly a bug. It's happening on the new blades as well from what I've read in a few places, so it's not just a blade1 thing.

I have also noticed a pattern, if I disconnect blades from the network and let only one come online, generally speaking it works like a champ, 10-13gh. Within a minute or two of putting another blade on the same network (regardless of if its connecting to the same proxy/pool), they both go down. I continue to suspect something is up with how it's talking on the network.

Since this has occured, they seem most stable if they're allowed to hop between getwork and stratum (ie, put a getwork pool IP & a stratum proxy IP in the server line). If you force it to choose one or the other, it seems to simply fail to hash.

I see there's what appears to be a jtag/serial port on the NIC, I'm going to probe that tonight to see if I can find tty access.

Regarding the 24v input discussion

I took a closeup of the power lane section of the blade, presuming the chip I'm focusing on is schematically what we're looking for. It's a buck controller (DC to DC step down converter, often used in dropping 12v computer power down to CPU levels).

Here is a closeup of the area:



It's a Sipex 6133 model, 5-24VDC input, handles up to 30A.

Here's one of several datasheet links/possibilities: http://www.alldatasheet.com/datasheet-pdf/pdf/173439/SIPEX/SP6133.html

More than likely 24VDC could be used, however I wouldn't want to simply try it without examining the circuit to ensure everything else could take more than 12. Most components are rated 13-400VDC but, you never know.

Hopefully that helps with the discussion.

Thats possibly because the feature was added for 3.2.1?  I thought that was the case.

I have a fresh build of Ubuntu 13.0.4.  I'll spare you the details of wrangling with apt-get etc :|

I'm using Ubuntu 13.04.

Nice, that is handy.  Thanks!

My 4 blades are hashing fine but all 4 of them are switching server on the spot at 1 hour mark. I can't figure it out anymore, all is good yet switching servers.

I've been mining for 19 hours now, and its still averaging 8GH/s, reading from both BFGminer and my pool stats.

It turns out I had a copy of it on my work laptop from a while back. My blade is up and hashing. Thanks dogie!

If you are trying to setup your new blade and are having problems with the proxy download site being down, shoot me a pm and I will send you a link to my Google drive :-)
