Brilliant.
So I am moving things around in my closet to make space for the new UPS and line conditioner, and moving one of the power strips I manage to hit the on/off switch. Of COURSE, I had also unplugged the second power supplies for all the servers. Boom. All the servers go offline. And one of the servers won't power back up. Yes, dead server. Luckily I was able to pull the drives and load them into one of the other servers which is not being used, but now I have to repair or replace it.
Add one more thing to my list!
