So uh… How do you setup multiple miners? I can't figure out how to add any from the dashboard.

Ok Never mind. I figured it out. My router was having issues and I had to restart it.

New problem… I clicked "shutdown" on the initial Apollo that popped up on futurebit.local, and now I can't figure out how to turn it back on. Because I don't know its IP Address...

Figured it out. The common fix for any issues in this thread has been to reimagine the SD, so that's what I did and was able to get it back online!
