What were those switches for? (not the network switches, the physical on/off switches with the green and white wires)

Power switches. There were 4 machines per layer, 80 per rack.

They are the power LEDs/switches for each of the four motherboards on each piece of cork board. Yes, cork board. It's non-conductive.
