The BOB's were linked together (only 2 boards powered) and it went into a red fault. Then I tried only powering 2 hash boards with the bob's not linked and I got a dimmed digital readout on the 1 bob and then the one psu failed. Just curious, if you have 2 psu's powering 3 boards, and the PSU failed that is connected to the control board, what will happen to the S9, any damage?
