3:29 KLUNK - HMMmmmm "there it goes" - those are motorized breakers closing, energizing the rectifier circuits with 400V of three-phase power.
3:31 thunk-BZZZZZZZ "okay, all the heaters have come on" - the inverters have started.
This system takes massive AC from the mains, rectifies it to straight DC current, then inverters change DC back to AC. You get a nice clean power signal that way, without the surges or sags. Rather frightening sound, up close. You can FEEL the power in the air.

Boy, I'll bet it was cold in there, with just the UPS and the chillers running. Believe it or not, for those who don't know, that room was really really quiet. The mainframes were off. I didn't see any rebooting happening here, just futzing around with a sick UPS! I wanted somebody to click the GO button, and hear all those great old DISK DRIVES spinning up. They sound like jet engines spooling up. --disappointed.

Fascinating! I'm assuming that this machine, too, was scrapped?

Super boring video, but I watched it to the end, so thumbs UP. Gosh, it's only 15 years but it looks ancient!
