Key Findings [...]
3. Based on the electrical equipment log readings and the manufacturer’s official assessment, it was determined that the most likely cause of RCC shutdown was the “Emergency Power Off” button being manually activated.
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. Cheers, -- jra -- Jay R.
