Hi guys,

I've been trying to find a solution to some problems I have with one of my S9. Anything that can point me to a possible solution will be much appreciated. I've been reading and trying things all day long but sadly nothing has worked out yet. Much pain!

Here's the details:

The machine is an Antminer S9 13.5 th/s (dont't know exactly which batch but it was shipped on Jan 5 2018), bought from the manufacturer. The miner has worked well since I plugged it in for the first time around 7 days ago. This morning it has stopped to hash all of a sudden and since then I have those problems:

- Hasboards:
   the red leds on each hashboards are off.

- GUI: Sytem > Overview:
   nothing is displayed at Hardware Version
   nothing is displayed at BMminer Version

- GUI: Sytem > Miner Status:
   Displaying no information

- GUI: Sytem > Kernel Log:
   can't find any of the 3 hashboards
   can't find bmminer
   fan problem:
   - get fan[5] speed=840
   - get fan[2] speed=4800
   - Fatal Error: some Fan lost or Fan speed low!


Note that climate is near perfection, dry, fresh and very little dust. Chip temperatures ranging from 70 to 80. I just hope I won't need to send it back over there...
