The node is running fine. Every time I click start on the miner, the fan starts to spin up for about 0.5 second and then goes back to idle mode. I disconned all the standard units but that changed nothing. Checked all the plugs, green led is is on.
To recap: new SD & all units have red flasking LEDs but the miner won't start. Node runs fine.
What is my next step?
Try this:
1 - Turn off the node
2 - configure the miner settings
3 - start the miner, you will likely get the inactive hashboards issue you described
4 - stop the miner
5 - reboot the entire system, node should start syncing again + mining should commence
i just added a standard unit and ran into a similar issue. the issue i ran into was that only one hashboard would be active but the lights would flash or both would have trouble hashing. Restarting the system with the above process was worked for me.
Unfortunately this did not help. I even swapped the power supply.
