Thanks, I suppose I need to get in touch with someone then.  I have another rig that I cannot connect to at all.  I know I have the correct IP address on it but it will not let me communicate with it.  It just says the server will not let me connect to it.

Any suggestions on that one?

I'd try using a serial cable first, but you probably don't have one. Chances are high that the internal MMC has gotten corrupted or gone bad. Try a SD boot disk (or possibly a SD recovery). http://www.spondoolies-tech.com/blogs/technical-blog/13098521-sp10-sp2x-sp3x-recovery-sd-card-boot-sd-card-creation-instructions

Thanks, jtoomim.  I'll give them a try.

If I had a serial cable, what are you suggesting I do with it.  Also, all of my computers are Mac's with Windows 7 via Parallel's installed in my Mac's.  If I need to go to buy a laptop to do what you suggest with a serial cable, I'll do it.  First, I need to know what I would do with the serial cable?

Thanks!  Now I need to figure out what to do with the leftover wattage on the 20A (16A derated) circuits.  Not planning anything now on those except single SP31s on those circuits.  I guess I could underclock those and throw on my Bitcrane 110 units. They are not very efficient when compared to Spondoolies units but they could take up the extra slack running at 900w. So, with (4) 220v 20A and (4) 220v 30A circuits, I should have no issues running ten SP31s.  Also have about 6000w of 110v also available.  I'm running through wall Panasonic fans, wall vents and 18k BTU for cooling. That takes up (1) 220v 20A circuit.  Looks like I have room for one more SP31 on one 20A circuit.

Thanks for the reference charts. Very helpful.

Understood.  Looking forward to working with the new miners.  I'll let you know what DHL asks for.  I upgraded home panel to 400A and put in 220v 20A and 30A circuits.  I have 24A safely usable on the 30A circuits (5280W) with the derated PDUs. Do you think I can run (2) SP31s on each of those circuits as long as I underclock them?

I've been using 1 SP30/SP31 each on 16 amp 237V circuits for a while with no problems. I can often stick a little extra on those circuits, like an underclocked SP10. Those are PDU circuits, though, and the breakers are built to international standards and aren't built for the 80% derating factor. Your 30A x 220V circuits are less than twice my 16 x 237V circuits, but I'd expect them to still work even at full speed. (Actually, come to think of it, each two 16A circuits is fed by one 30A circuit in our setup, so the only real difference is 237V vs 220V.) If you underclock your SP30s by 10% or 20%, you'll be quite safe.

Speaking of underclocking...

On OS X, open Terminal, then run

Code:

screen /dev/cu.usbserial-<TAB> 115200

where <TAB> is an actual tab keypress. It should autofill to something like /dev/cu.usbserial-A603PRMX. Plug the serial cable into a working miner and press enter, and then you should be prompted to log in (root / root). Works? Great. Now try plugging it into the troubled miner, and press enter. If you can log in, then the machine is booting, but something else is going wrong. You could try running ifconfig to see what the IP address is. If you can't log in and you see a bunch of Ç or C or ç (or something) characters appear on the screen at a rate of about one per second, that means that the miner can't boot off of the internal MMC storage for some reason. If that's the case, use a µSD card to either recover or boot.

I think the cable you need is this type, but I can't be sure since I was sent a few directly from SPTech and never bought them myself. You might also be able to make one yourself a bit cheaper by using an FTDI USB serial cable and soldering (or splicing) on an RJ12 connector on the other end.

Thank you for your time and patience.  I'll give this info a look to determine what to do.

The only problem is:  My 17 inch MacBookPro has Thunderbolt, Fire wire 800, ethernet and USB 2.0; no 9 pin serial port.  I'll need to get an adapter.

I had a couple that would not connect through the SP-tech myminer.io landing page, even though they were showing the miner and IP.  I was able to connect directly to the miners one at a time using tftpd32 as a dhcp server from Windows (disconnected from my LAN), pinning a static IP to the miner and all the pool/asic settings.  Put it on the network and it was G2G.  I think the IP my router had assigned to it initially had a conflict or something.  It's something simple you can try before moving on.

Edit: unless i misunderstood and you already assigned the static IP, in which you can either do as the other gentleman recommended or do an SD card recovery and start over.

That's why I linked to them. Note that the default theme for this forum makes it hard to see the color of links sometimes. I bolded the links in this post.

I'd recommend just going ahead and doing the µSD thing. The serial cable is useful as a diagnostic, but you can always just try the fix (µSD) and if that works, it's as good a diagnosis as any.

I'm going DHCP and my Airport Extreme BaseStation does not show me what IP Address it assigned to it.  However, I know how my browser reacts to an authentic IP address versus one that is not.  Myminer.io gave me the IP as it did all 14 other rigs.  I could connect to all of them just fine except for this one.

I have my Airport set up for DHCP and NAT

Wonder if I should do DHCP only?

I want the serial cable and the experience for diagnostic purposes in the future.  I need to get me an adapter from Thunderbolt 1 to 9 Pin serial.  Then 9 Pin serial to ethernet to go into the serial port of the SP20.

It's RJ12 (6 pin), not RJ45 (ethernet, 8 pin). Just use the USB serial adapter I linked you to.

I'm going DHCP and my Airport Extreme BaseStation does not show me what IP Address it assigned to it.  However, I know how my browser reacts to an authentic IP address versus one that is not.  Myminer.io gave me the IP as it did all 14 other rigs.  I could connect to all of them just fine except for this one.

Myminer.io has very long memory. It will list machines as "Online" even if they've been offline for days. If your Airport Extreme doesn't show it, then chances are it's not actually booting up and getting a DCHP lease, which suggests that the MMC is bad. Either that, or the ethernet cable is unplugged or something similarly silly.

Sorry I can't really comment, I'm still learning networking as a whole (and mining has been invaluable to make me have to learn).  In my situation, I wanted to narrow down as many variables as possible, so I directly connected the SP20 to my PC via ethernet, disabled wifi, and ran tptpd32 to create a dhcp network for the SP20 outside my LAN. Once it has assigned a lease, it lists the devices in the software.  I was then able to get to the GUI via web browser and set it up as normal, and avoid whatever IP it was being assigned from my router that would not allow me to connect to it (even though it would show up in the myminer.io interface).

I had success using DHCP only, so if I was you I would try it. And use a program that lists the leases so you can be sure it is connecting. You did try different ethernet cables right?

Have you looked at the connected devices on router?   Assuming you know 14 of the rigs that should cut down how many IP's you need to try.

And there are apps that scan but device list is easier for most.  If you "have" to scan you can use angry ip scanner - http://angryip.org/ (Make sure to use your network IP range if done wrong you could be scanning something you don't have the right to)

[dmwardjr]

I was able to get it to wake up.  I went to the Apple App Store and downloaded an app called, "LAN Scan."  When it scanned all of my IP's on my network it triggered something.  It forced me to re-enter my admin passwords on each of my SP20's.  It's like it disconnected them from the myminer.io... making me have to log back in to each rig.  Well, when I logged back in to each rig, I no longer saw 192.168.1.43.  However, I did see a new IP of 192.168.1.57 and it turned out to be that rig that I was having problems with.

That was the weirdest thing.  Cause I refreshed the myminer.io page several times during the day to see if it gives me a different IP and it never did.  Once I downloaded LAN Scan and it did it's business, it's like it made myminer.io give me a new IP address.

Since we had some discussions about gen3 miners I would like to congratulate SP-Tech for their 600 page with a special image:

[ManeBjorn]

I love that sign.
Great work Spondoolies I look forward to reviewing your next gen miners. I also am eagerly looking forward to our interview next week.
