I have a Batch 6, it is beeping.
The lights on the hashing boards flash right before it starts beeping.
The power draw from the wall is nominal (389 watts - typical for the miner not running).
The light on the front is red.
The temperature reported is 20C
I stopped the beeping by pressing and holding the button for a few seconds. My PSU power output is 12.2V, current power draw is 1121 Watts.
No X's, no other info, just beeping constantly while fan is at full blast.
Any chance it can't get to the Internet and your pool? The beeping and fan sound like "I can't to the Internet and need help. I'll run my fan and beep until then".
I don't own an S7, so I may be way off.
For me if one of the fans is not spinning it will just go into beep mode.
If one fan goes out the one that is working may spin it a bit, have to look at it with a flashlight to make
sure it is really spinning under power.
