Title: hashboard not working after internet disconnected Post by: condourfx on March 04, 2017, 11:27:18 PM I have antminer S9 and the internet was disconnected for 1 hours and work again but I see one hashboard not working (the red led off) I try do restart many time not work.. I check the board if burned or damaged but its fine and I don't see any damage . I try connect this hashboard only but not working also . Now I disconnect this hashboard and the others two board working good. I've noticed when I connect and power on all hashboard ,the antminer Restart several times but two hashboard work good and the other one not working ( red led off) how can resolve this problem ?

Sorry it happened to you. Thanks for reply I try upgrade or change firmware I use this file to upgrade : https://shop.bitmain.com/files/download/s9-20160715-600M.tar.gz I wait 20 minute after upgrade but nothing happened , I do reboot again and the all 3 hashboard work for 2-3 minutes normally and Hashrate increaset to 12 TH but after that one board stop hashing .. I think problem from firmware or control board because all hashboard can work but one of them stopped , I will try replace control board or try use another firmware , What you think ?

Please post the kernel log after booting and hashing for a bit. This will greatly help in troubleshooting the issue.
