NEW YORK CITY TRANSIT RAIL CONTROL CENTER POWER OUTAGE ISSUE ON AUGUST 29, 2021 Key Findings September 8, 2021 https://www.governor.ny.gov/sites/default/files/2021-09/WSP_Key_Findings_Summary-for_release.pdf Key Findings [...] 3.

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.
