Hello, good day.

I bought 17 S3 miners some months ago. I'm a happy customer so far.

One of my miners suddenly stopped working. I pressed the reset button, but nothing happened. Both red and green LEDs are blinking; I can access the miner's web interface and this is what it shows on the "Miner Status" page:

I flashed all my miners with the latest firmware months ago, and all of them were working well so far until now.

Can anyone give me some directions on how to fix this miner?

Cheers,

Try a hard reboot
Try ribbons on controller
Faulty controller?

Shut it down and unplug supply and ethernet, let sit a few minutes, replace cables and fire up.

If still doing this then try running nmap from a linux machine and see what ports are open on the device.

I did the recommended stuff. Long story short, it seems to be the controller.

Test bench:

Testing left controller connector and left blade: It works.

To discard the ribbon cables, I repeated the 1st test twice, once per cable. As expected, everything went OK.

So, the next step wold be to file a RMA for the faulty controller, I think. What are the steps to do so?
