Title: S9 Possible Bricked Controller Bounty Post by: Kyphon on November 27, 2016, 04:08:32 AM The antminer s9 in particular we are having issues with is kinda a fluke. it won't ID on the network no hashing board light up when you push the reset both green and red lights go on. Ip scanners don't Pick up the miner that is having the issue but pick up all the others.
So first of let me say what my team has attempted to do thus far. Power on let run for 20 min. Attempt to reset by hold down reset for 10 seconds. - No change Access Restore options from the device its self (Pull up previous ip address that miner has used and it will pull up the standard miner page but half of the options won't load.) Swapped out PDU PSU every cable from miner to switch and back to outlet. still no gas. we believe it was caused by a error when the Static IP was being set as two of the 20 miners had this same issue. The second miner has the exact same issue and was located at a different location. The only common factor is the update on the static ip. It was successful for all the other miners but 2. we normally try and make a transition like that slowly so that it can be monitored. but for what ever reason these two miners didn't react as planned. Any recommendations on this would be a great help. Thanks in advance. Bounty is set at .5btc for anyone that can fix this issue.

I'm working with the warranty now. Just figured i would see if there was a solution beside going through the warranty that anyone knew of. Title: Re: S9 Possible Bricked Controller Bounty Post by: Elphamyto on November 27, 2016, 05:56:23 PM Is it possible to access the controllers on these units via serial connection? If so, you could grab a cheap UART to USB adapter from somewhere like SparkFun and see if you're able to open a terminal connection.

I had actually ordered a new microsd card and adapter to try this but before the stuff arrived I had figured out a solution for my issue so I never tried it.
