Help using two antminers s9 with one controller board

[magu99]

Hi Guys, this is my problem:

I have one antminer S9 that doesn't start up when plugged in (the machine worked fine for 2 months), the only thing that works when plugged in is the fans, all controller board lights and hashboards lights are off, I tried replacing the PSU and it didn't work.  I think that the controller board is damaged and that is the cause of the problem. My question is, can I use one controller board of a working S9 to run the hashboards of both machines, can I run two antminers S9 with only one board controller???

It might work but it would be tricky. One issue would be controlling and monitoring the fans. Another issue would be cables, connections to the controller, and whether or not the controller and firmware would cooperate. An easier fix would be to just buy a replacement controller, they seem to be abundant online.

My recommendation:  Swap the hashboards (or hash cards) and isolate the problem.

If your at 2 months, your still under warranty.  If you can prove its a controller, Bitmain will send you a new one.

No you cannot control 6 boards with one controller without some hacked firmware that im not sure exists.
