From: "Sean Donelan" <[EMAIL PROTECTED]> Subject: History of the EPO (Emergency Power Off)
The interesting thing about the EPO and data centers is it wasn't
orginally for life-safety, but came out of a recommendation by IBM to the NFPA for property protection.<<Fwiw, the EPO on IBM's mainframes back in those days, had to be -pulled- and had a mechanical 'latch' that kept it from being pushed back in. Took both hands to reset it.
