Does the B8 miner have a total number of two PSUs?

After I looked at your logs, it seems to me that there is an error with the PSU in the first slot (slot 0).
It looks like the miner is unable to communicate with the PSU. And also it most likely does not give any DC voltage output. This could be verified with a multimeter.

Do you have a new PSU you could try?
I think it has to be the exact same type as the old one.

edit:
Based on all the info I've got,
this is the power supply model used in the B8 miner:
Eltek Flatpack2 48V/3000W HE
https://www.eltek.com/us/products/flatpack2-483000-he/

I know now how to operate a Huawei psu in b8
login with putty and write the command echo -n ' -no_psu '> panel/home/data/conf/- no_psu
now b8 hashing

That's great! I gave some merit.

Can you also share the exact details about the Huawei power supply model you are using?
It would be big help for other B8 users in the future.

or any psu 53v

Thanks! So one alternative power supply model for Bitfury B8 miner is Huawei R4850G2 power supply.

I saved the datasheet here for long time archiving:
https://mega.nz/file/E9lAkBoY#8qYt1nsjHtJ3ajAXMzkkfmUtiWPYkm0W1fy9fqMqO8w

Using this psu model requires the small mod which zoghotaa described earlier.

Is there any kind of debug logs you can pull up and post? If so, hopefully they could point to either a setup problem or PSU issue. If ya got logs, please use the code button in the tool bar to do it. looks like #

Bitfury B8 is a really rare miner here at Bitcointalk.

Another variant of it goes by name Facemen FM2018-B8.

I only know that it uses a 48VDC power supply,
and you need enough power capacity.

You might found more info from Bitfury themself or from Russian language forums (maybe bits.media).

Dear members
I changed eltek flatpack and use Huawei power supply
The b8 is up and working normally but not hashing
Please guys is there anyone using Huawei power supply . What changes I should make to start hashing
Thanks

I have the same problem and I'm looking for a solution

I am using same output voltage power supply same features rectifier model 48 - 53 voltage
As per i know the missing is software modification but not one of the common use frameware used by most of us
I wonder if there is modification could be done with cmd command or whatever

It might be not hashing due to PSU you are using Bitfury b8 miners needs 6400w power supply.

If that PSU can't provide enough power then it won't run properly you must use a power supply that came from Bitfury or use a PSU that can provide enough power.
