I have 2 hp 1000w psu's with X-Adapter REV 2 & 14AWG THHN Cables(the kits you see on amazon, etc). I can't get the red light by the ethernet port to go off. I think that light means it's in some kind of fault mode. There are no stats in the miner status page, not even the fans. It's like they don't exist. I need to figure out what the problem is. Can I just plug in one board at a time to see if they work independently to see if one of the boards is bad? I unplugged everything and checked the power supplies and was getting 12.79V on all 10 connectors.

All 10 power connectors are plugged in. The control board is connected to all 3 hash boards with the ribbon cables.

Any help would be much appreciated.

Try connecting the control board first.

Do you mean in powering up? I have turned them on at the same time and then the 2 hash boards on one ps and then the other hash and controller. So you want me to reverse that order?


and thanks for your help

No, you did it right. Regardless you should see the board. It look like cgminer is not starting, this is something that could happen if you bricked the controller by trying to update the firmware.

You'd have to post the log and see why its not starting. But that's a bit over my head so someone else would have to help with figuring out your log, assuming you did not mess with the firmware.

I have not touched the firmware.

How is the wiring split on the 1000 watt PSU's?  And are you running them on 120 volt? 

Looks like on 120 they go down to 800 watts.  So curious on your wiring.

1 ps has 6 connectors and runs 2 hash boards. 1 ps has 4 connectors and runs the other hash board and the controller. Yes, it's 120V.

I hate mixing PSU's I would see how others with this kit are doing it with 120.  But each board is going to use more then the 400.  So I don't think 1 of the PSU's will run two.  If it was on the 220/240 with 1000 watts it would run two.  But your giving them to few of watt's I think on 2.  Unless they are underclocked then you could depending on settings. Also I'm assuming it's a batch 8 or 9 in this.

So ask seller if they do a mix of how they do on 120.  I would sit it aside till you get that anwser from seller or someone on here who has used it.

Hmmm....so you think this is a power issue? I based my system from what I found on the internet. This sucks.

Dunno, if thats the case you should be able to set a lower clock, reboot the thing and then it would work.

Did you ever make a screenshot of your pool config page? I'd like to see it.

Assuming it's a B8 running at default 800 watt's is not enough to run 2 blades.  That is a 1000 watt psu only on 220/240 so would work fine there.

But he will have to underclock to get 2 blades running with 800 watt's.   It might not be only issue but it is for sure at least one issue.

I don't know if either one of those links work. Do you think setting it to 600m would work? Or do I need to go lower?


The psu's says it puts out 900w with 120v. If the whole system is 1250ish watts, that is a little over 400w. I will get another psu tomorrow to find out for sure. I am going to go try to underclock it and see if that works.

I just underclocked it all the way down to 400M and still nothing. I am not sure if yall can see them or not, but the links in my post above is a pic of the miner status tab. Nothing is reading. I don't see any X or O to show the status of the chips or the speed of the fans, just the categories are there. Does this mean that the controller is bad? I don't think it's a power problem with it being underclocked so low. Thanks for all yalls help so far, hopefully only a few more steps till mining.

did you configure a mining pool yet? Input your pools, could be a long shot but it sounds like the PSUs are not strong enough since its not 240v and is 120

I have set up my pools. I am going to try to buy a bigger power supply tomorrow. Then we should know for sure. I don't know if it makes a difference, but it is very loud. After about 30 secs after boot up, I think the fans go to 100%. I have seen some videos on youtube and such and they are not even close to how loud mine is. Don't know if that means anything or not.

Just to make sure on network if you log into miner.  Then click network, then diagnostics and it should have bitmain's site is it successful when it tries to ping?

Hey check your pm

Naw a screenshot of your pool configuration page. Not the miner status page.

I have a feeling it's a controller issue? Even if he had wrong pool configure info that info should show up on status page but just show dead I believe. So if under powered you should still see this I would think. Are the fans running?

If you input an invalid argument to cgminer it will not start and as such you will get the result OP is getting, with no data being shown on the status page. Just try inputting an invalid argument in the config or on the launch arg file in ssh or scp and you will see thats what happens too.

So yes it could be hardware controller related but you should rule the rest out first, such as software controller related. After that, making a backup for the image file and then putting in a clean one would be the next thing to try.

There is my pool page. I bought some new psu's today and it is still not working. Yes the fans come on about 30 secs after I turn it on and they run wide open at 100% and are very loud. They vid's on youtube are not even half the noise level as mine.

VirosaGITS - I have no idea what you said. I do not know linux very well and didn't think I had to do all that on the S7. That's why I bought it and not other machines. I don't even see a command line to do all that.

The network is working because I can log into the machine and I have pinged a few sights inside of the S7 software.

Btw it is a batch 8.

The controller boot from an .img, if the .img is corrupted somehow it could fuck over CGMiner. And no you should not have to do this. If its a B8 then its probably still on warranty, if you received it like that, you should contact Bitmain and ask wtf if you have not already.

Maybe, just maybe Bitmain put the wrong firmware on it, i honestly don't know.

All i or anyone can do is probably have you check some things to figure out what is wrong. Bitmain may very well blame the PSU's. But assuming they are in working condition, you should of still been able to run the S7 at lower freq or with just one blade for example.

A good thing to do would be to try with a proper PSU in the meantime.

I have 4 proper psu's and have tried all of them. I have underclocked to 400M and still nothing. I have tried one blade at a time and still nothing.

I didn't buy it from bitman, would they still honor a warranty?

Thanks for everyone's help so far. I am leaning toward the controller board because not even the fans rpm are showing up in the miner status tab. That would have nothing to do with hashing or enough power because the fans are running at a 100%. How do you know they are running at 100% you ask, because of the noise. Wow, they do put out some air, but the noise.

The fan RPM will not show unless the miner is mining, because it all goes through CGMiner. Either you would see everything and see dead boards, or you will see nothing. You can't have half.

You will have to contact whoever sold it, since they're the ones that sold you a bad unit. Who did you buy it from?

CryptoCrane, when I bought it they said I had 3 days. Today is day 3.

Do you know how I can try to get CGMiner started?

Thanks everyone for your help. I contacted the seller and he is going to take it back.

Thanks again,

Zerb

I am very to happy to hear that you are going to replace it.I have got a suggestion just power 1 board and control board.If it is an issue related to PSU you can define the problem by that way.I believe it is a PSU related problem.If it does not start to work the problem is probably the BB.
