I received my 2 Antminer S3's today. One is happily mining away at about 430Gh/s the other I logged into once and attempted to configure it but something happened and the S3 rebooted and now I am no longer able to sign into it. I have changed the working miners IP address so its not conflicting and the miner does show on my router at the 192.168.1.99 address. but the page will not load and I get an error saying the page could not be loaded. Is there some magical reset or something to recover this or am I SOL?
You could try resetting it to 'factory default' using the reset switch on the 'front' panel. See
https://bitcointalk.org/index.php?topic=702653 in the Troubleshooting section where it says
"How do I reset settings to default? - Use a paperclip to press the reset button - located next to the ethernet connector - down for
5-10 seconds. The miner will then reset with stock settings."
If that fails, you could try powering it down and after some minutes up again and hopefully it will sort itself (some patience is required, it is a slooooow controller, adequate for the task).
(just wondering why does the S3 'show on my router at 192.168.1.99', if you left it with a different fixed IP)
Cheers
