[b] Avalon 851 pmu change problems [b]

[Ahmedhamoud]

Well, I have 5 Avalon 851 devices. They had a problem with the pmu socket due to the low current, which led to the damage of the sockets. The important thing is that I disconnected them for maintenance and they are working in full capacity and with the full hash. I ordered 10 pieces of PMU left and right from the zues and they and when I install the pmu it works perfectly, but the device It does not give a hash, only the four lights of my pmu work, and it should give the hash, then it gives me 0 hashes and the four hashs 0 0 0 0 knowing that I brought devices that are already working and I moved the Pmu from it and tested it does not work and when I return it to its own device it works well what do I do now? Do I have any experiences or

Can you access the miner through the browser with your miner's IP?
If you can then go to the advanced version and look for CGMiner API Log and paste it here but make sure to post it inside the code tag(a # sharp button) so that we can easily read your API logs.

Also, I would like to suggest you follow the guide on how to troubleshoot this unit from this thread below
- https://bitcointalk.org/index.php?topic=3224256

[Ahmedhamoud]

I have read this entire topic and did not find a solution. It only tells you that there were malfunctions, and I have no malfunctions in the pmu or the hashboard, but the problem is when replacing the pmu or moving it from one device to another, the hashes do not work. Is there a specific definition or a way to identify me Hashtags specifically or a program or something like that

[BitMaxz]

How about the API logs would you mind copying the whole thing and paste them here?

Maybe we can see the reason under that API logs without them we can't identify which exactly the issue of your miner is.
Or your miner is totally dead?

I don't know if there is a tool that could detect the problem with this unit or to check the hashboard just like on Antminer units where you can able to test each hashboard.
Why not try to contact zeusBTC and maybe they have a tool or software that can able to use the same as testfixture.

We only need the top part of the API log eg like this from an A841:

[Ahmedhamoud]

These are the settings after changing the pmu. Is there a solution to this problem?

[BitMaxz]

PG is 15 which means the PMU is normal.
I could only see is the two logs with abnormal value both ECHU and ECMM.

Now start with those logs check this image below


Now you should got the idea base on description logs there might be issue on mm board or connection problem.

[Ahmedhamoud]

I already know that the pmu is healthy and there are no errors, but the problem is between the connection between it and the hashtags, or the identification between them, so what should I do with this?

[BitMaxz]

Can you try to flash the unit first you can download the firmware here https://download.canaan-creative.com/
I hope that it's just a firmware issue.

If you don't have the tools and technical knowledge to test them physically I would like to suggest you hire a technician you can check https://www.zeusbtc.com/Repair.asp and ask them about your issue.

But if you have some tools like a multimeter you can check the connection from the MM board, cables, and connectors and maybe there are some parts that do not have a connection or there might have burnt parts.

[Ahmedhamoud]

My friend, do you mean to update the unit? Is my software version the entire device, the device is a PMU, because I tried to update the software for the device, but there are also soft files for the pmu, including a file in the bin format, but I do not know its function or how to burn it on it, and I will show you the problem in a simple way More Is it when you get damaged in Avalon 8 PMU devices and you want to replace it? Do you just remove the old one and put the new one? Or is there a procedure to be taken as identification or connection because I am 100 by 100 that I have no problem with the hashes? And when the pmu was returned to its device, the devices worked efficiently
