Title: Boot problem whit avalon 841 Post by: xnoar1995 on September 19, 2021, 09:32:43 AM Hello friends, I am new to the group and to the world of mining and I write waiting for help, I have 2 avalon 841 miners connected in series, suddenly they stopped working and I see that the auc3 converter does not indicate any connection led, only the led that is on and the machines when turned on remain in a waiting cycle with the back light in green. Is it possible that the auc3 converter has been damaged or should I check the machines?
Thank you very much in advance for the help you can give me!! Title: Re: Boot problem whit avalon 841 Post by: kano on September 19, 2021, 11:52:26 AM Check the power leads.
Make sure they are connected properly and maybe even give them a wiggle. You should also have coloured lights next to the power leads. Red = bad, Yellow = good. Of course, the top back light should be blue when it's mining.

Now when you turn on the machines, the light in the center turns on white, they turn on strong as when they are working and then the fans turn off as if they were in a waiting cycle and the light turns green. All 4 side lights of none of the 2 are seen on. Sorry if the translation is not well understood I do not speak English very well, I am using a translator.

Is there any way to view it from the pool or elsewhere?

Can you run with just 1 miner connected to the AUC? You should still be able to access the Avalon GUI (but not see the AUC or miners)- use the Advanced interface. Can you access it? Try a different USB cable, remember it MUST be one that can 'sync' as well as charge (some USB charger cables are charge-only and do not have the 2 data lines we need). |
