What is the correct procedure for powering up and down a studio?

Ive always been curious to know what all of you project and pro studio owners do as a standard procedure when powering down your gear?

Hi. I always wondered about phantom powered mics- which should I do first?
Power down mixer (phantom power), unplug mic cable, or turn off mic channels? Does it matter? Obviously I bring down faders and monitors first, but then what?
