my T17 of just a few months stopped responding today around 130pm EST. I went to check on it when I got home, it had the fault light on.
First, I turned off the power, check the outlets, the ethernet cable, after about 5 minutes, I turned the power back on. Miner powered on but the "normal" light was not lit but neither was the "fault" and I could not log into it via the ip address.
Second, I tried a known working ethernet cable from one of my other miners that was visible on network. Did a restart of the miner, waited 10 minutes and nope could not see the miner on the network. So, I put the ethernet cables back to original placement.
Third, I did the reset process. waited about 10 minutes and tried to log into it via ip address - still nothing. So, just if for some odd reason it was given a new IP address, I rescanned my network and nope no new devices and no new ip addresses assigned.
Fourth, now checking to see if it is still under warranty. Got this message from Bitmain site "Equipment warranty period 109 days remaining."
So, I guess I am contacting them to send it back. Sucks to have that down time though.
I purchased a psu from them just in case.
Try one more thing make sure both power cables work with 220 or so. And make sure both power cables are fully plugged in. The controller does not work with a loose power cable.
