can somebody tell me what wrong with my S9 miner?? Just run for one month. Can I fix it at home??? please help me
Looks like a board gave up. Try power cycle it, see if it comes back.
do you mean restart the miner???
Yes, unplug it, wait a couple of mins, plug it back again. Maybe save the kernel log if you haven't rebooted yet? Maybe the board comes back up? Kernel log after the reboot may tell you what is going on with that board. Also look at the red led in the board, when mine broke that led never turned on again.
