the antminers are all plug and play.
Now if you are looking at the software page for updates then dont. hit the little red X at the top right of your window and you will be thankful. Several units/people have ended up turning their units into expensive paper weights because they updated to the wrong software.
That's only if you flash an antminer. Unless you're doing some really high level software flashing, installing software like kano shouldn't do anything bad. I assumed that's what OP is looking for right now.
No OP wondered if he needed to download any software for S7. He was a new miner, and was talking about just running. Was nothing like firmware or kano. Was just wondering if software is needed to get started....
With a S7 it is not you log in via IP it's all there. We can let this thread die
Op got anwser already no need to bring this back up really.
