I don't even *do* datacenter for a living, and I know that when you hit the
Molly button, 

1) A Klaxon goes off in the Data Center -- one that sounds *different* from
the Halon Klaxon, in both cadence and tone (just for a couple bursts), and

2) Yellow rotating beacons turn on, and stay on while you're on Emergency Power.

Yes, real honest-to-ghod *rotating mechanical beacons*, none of this flashing LED
crap.

Clearly, it's important that the use of Emergency Power be annoyingly noticeable.
