This question already has an answer here:
I'm running OS X 10.8 Mountain Lion on several servers. We're about to ship them off to a colo provider, and I wanted to prevent them from sleeping.
My question is, does setting the System Preferences > Energy Saver > Computer Sleep option to 'Never' reliably prevent sleep?
I noticed yesterday that all the mac minis were off, despite the 'Never' option being set. However, I'm thinking their power strip may have just been accidentally unplugged for a second.
