My a2 is currently under a rental contract, once that ends in a couple of hours I will check and report back here later this evening.
I have minera installed on an sd card but can not figure out the ip or a way to log into the machine once installed.
Download Angry IP Scanner. That can help.you. After you find the IP, You can SSH into it with the username pi and password minera. Then after logging in type sudo su to get root access.
