I experience the same thing. I need to do a power shutdown every 2 weeks on a machine. Before turning off the power supply which command can I run with SSH to cleanly shutdown the machine?
On the C1s, if I reboot (GUI) they do not come back up cleanly, you have to reset the power switch.
When I say they don't come back up cleanly, I mean the hash rate does not return to the
1000GH/s. Maybe 760 GH/s
Often times the ASICs on chain #2 or chain #3 hashing boards come up all --s or ..s
