t17 40ths

[Hamid29]

hi everyone,
I have a small farm with 12 T17 40THS
the cooling system and air-conditioning is well
the Devices face the same problem one after another, and that problem is:

Code:

error: get_temp_info:  read temp sensor failed

That will turn off the hashboard, while the next device is running smoothly at that moment ,However, the temperature of the farm is usually between 10 and 30 degrees Celsius.
I've reboot them several times but the problem apeare in about 1 day.
is there any sujestion please?

Okay 12 pieces of t17 correct?

Could you show firmware?

It is on the system page

Code:

System
Miner Type	Antminer T17
Hostname	antMiner
Model	GNU/Linux
Hardware Version	19.10.1.3
Kernel Version	Linux 4.6.0-xilinx-gff8137b-dirty #25 SMP PREEMPT Fri Nov 23 15:30:52 CST 2018
File System Version	Mon Jul 29 00:19:06 CST 2019
CGminer Version

There are a few versions of firmware.

do you have the one above?

https://service.bitmain.com/support/download?product=Antminer%20T17

there is also this one.

and there are older ones.

Does the machine start-up and run normal for any period of time? If so then it could be an issue like below. If not then it sounds like a hardware issue.

Can you tell us more about how the miners are placed? Is this happening to more than 1 of your miners? Does the problem happen more when the temperature is closer to 30 or is it sporadic? What sort of board temperatures are you seeing on the miners themselves.

Your space may be cool enough in general but you could also be facing an issue with short-circuiting airflow - warm exhaust making it's way to the intake. I haven't had an antminer in a long time so I'm not familiar with that error.

Code:

error: get_temp_info:  read temp sensor failed

its bad sign, its mean motherboard or hash board are defective, captor dont give temperature...

Try checking the wires to the hashboards.

This is what one of the steps that Bitmain sends out if you contact them about the issue.

1.check the wires for the hashboard--pull them and re-plug them again, and also you can try to change the new wires.

Not really, there Kernel log is not a holly book, the problem is not seldom stated explicitly in the kernel, i have a few miners that have the temp-sensor failed problem and they work without an issue.


OP, use common sense, if the problem happens to more than one miner then it can't be cables, wires, etc.. it has to be something they all have in common, which is one of three.

1- Voltage
2- Internet
3-Firmware

Given that they are T17s, these gears have almost zero tolerance to voltage drop, if you are not feeding them stable 200-240v, they will act funny, the reason why one will fail when another one does not, could be because the voltage regulates / increase when one miner goes out of the equation.

I can go on and on explaining all different possible, but to make your life easier, try to shut down half of them, keep half running, if the problem goes away, then it's your voltage/internet, if not then try a different firmware. It can't be anything but that.
