It turns out that the S1 Bitmain Antminer have a small speaker that produce beeping sound when there are errors. I don’t know the exact error nor I could find documentation on the beeping sound error definition. My guess is that it’s similar to mother board post beeps, but so far cannot find documentation on translating those beeps code.
In my case, when I configure the S1 Bitmain Antminer. I accidentally configured the static IP of the Antminer to 192.168.1.255 and my network router hub switch doesn’t like it, or should I say that Antminer does not like this IP 192.168.1.255 I thought I saw an error message, but I went through the configuration so fast that I didn’t get a chance to read the error. I might have also clicked on the Switch Protocol something that might have messed up the configuration as well. Also I believe that IP # 192.168.1.255 when typing in the Antminer it should have red cannot use it. Anyhow after clicking on Save Apply changed, I can no longer connect to it, whether it’s the new IP or the old factory IP of 192.168.1.255. I had to do a factory reset by pressing on the reset button on the controller board which I have blogged previously.
