Thank you all for your answers. I have to move my  to another location and I wasn't sure how to shut down and didn't want to hurt anything. Thank you again.

I searching but could not find a topic on this. When you are running multiple miners, say four, how do you set up using a pool? do you open one account then work three miners and open another account for the fourth? Or do you open four accounts one for each miner? Also do you open a wallet for each miner or just use one wallet? I am a fairly new and trying to learn the best way to set up. Thank you to all.

When using more then one antminer s1 which way are they supposed to be stacked, boards horizontal or vertical and how many can you stack? Does the way you stack them make any difference in the cooling of the antminer? I have seen them stacked both ways which brought up this question.?

I am running one S1 Antminer and everything is doing well. I want to add a second S1 along with a switch for the router and a surge protector. What is the best way to shut down and add this hardware and is there a good time to do it?

Got it mining I had the wrong address for the miner. Thank you for your help!!!!!!!!!!!!! 

Oh OK. Thank you. The GUIMiner window says it is using device GeForce GT 620 which I guess means it is mining with my video card. There are no other choices in the drop down menu so I need to figure out how to mine with my S1. Have you ever used GUIMiner? Thank you very much for your help. It is starting to come together.

I'm not sure what cpu/gpu mining is. I am using an S1 with the software GUIminer in slush's pool and the popup window for the GUIminer has at the left on the  bottom - shares:19 accepted (which changes) and on the right is has 17.1 Mhash's (which changes between 16 T0 17) . I was guessing the 17.1 Mhash's if the speed, am I right and isn't that slow?

OK I'm new. running Guiminer on antminer s1 and when mining from what I can see the guiminer says I'm doing 16 to 18 Mhah/s, is this the correct speed or do I misunderstand another part of tthis venture? Isn't the s1 able to do something like 180 ghash?
