I have a problem, if someone has any ideas of how to fix this.
when updating firmware from 2.2 to 2.8 a few miners crashed. I cannot reach the miners through their IP (i cannot see their IPs anymore).,
When I watch the power consumption I can see that the power usage does not rise above 170W, so the system does not boot.

Is there a program to fix this through the cable as I cannot see the IPs anymore?


So my conclusion is that the flash on several miners has crashed and i cannot update the firmware. Is there a manual way to get into the miners with a cable (there is a port on the miner) and instal new firmware?
