Well, it connects to the theme in the sense that - you're locked until you activate all the consoles - that's how you can get out. Although it highlights the activation of the consoles and keeping the connection on, it also needs you to 'unlock' the next level by turning on all the consoles. Yes, I agree, that the 'locked/unlocked' part is a bit overshadowed, but there is a reference to the theme. :D
