Can someone answer a few basic Innosilicon A4 hardware debugging questions:
1) Can you switch Hashboards in within a miner without harming/effecting mining?
2) Can you replace a bad hashboard from another miner (same model) without problem, or do you have to match a Hasboard ID# printed on the board (if so where do you find it)
3) If a hashboard doesn't Light-up, is the problem in the hashboard, in the controller, or potentially in either?
