I noticed that both lights are off. I referred to bitmain page which suggested a faulty board. Is there a way to confirm that?
Since you are using modded firmware from asic.to the only thing that you need to confirm that the board is faulty is by using a test fixture.
And why not try to run the miner again but this time enable the autotuning?
I read the documentation about this asic.to firmware and according to it if it's not mining you can try to enable the "Resolve Dev Fee".
And under "mining profiles", you can see how this miner will shutdown/restart automatically it has only two options either the miner has HW errors more than the value you set or if the hashrate is dropping.
What I would like you to try is to flash it again with that firmware or try to switch to brains OS.
