One thing could be the fan power connectors could be in the long plug positions.
Make sure the front Fan is in FAN1 and the rear fan is in FAN3 position
PICTURE HEREIf the fan connectors are in the correct position, please make sure the both fan(front & back) are functioning. Sometimes if one fan works, the other fan may spin due to the air pressure but may not be functioning.
If the fans are working correct, then your hash PCB needs repair. If it hash at the initial power on, you may want to get it fix while it is still fixable.
If you are in USA you can ship it to Colorado, or you can send it to Hong Kong for repair.
Hi,
hope someone can help me.
Yesterday one of my S7 suddenly stopped hashing and started beeping.
When I restarted it one of the has boards instead of showing oooooo just showed ---------, what the miner would do is that it started hashing for a couple of minutes and then stopped.
They miners are in a controlled environment with several other miners with constante temperature of 55 C.
Also tried with all 3 hashing boards connected change the frequency to 250 and same thing happened.
I tried to test connecting just one board to see which one was not working, with just one board connected it starts hashing normally for a few seconds, then the miner restarts as usual and when it comes back up the temp on the hash board is 95 so it stops hashing.
I tried with the second board, only that board connected and same thing happened.
Tried with different terminales and cables on the PSU.
Haven't tried with the last board since I don't want to damage them.
Could it be the PSU? Any advise would be greatly appreciated.
Thanks
