Not my recollection at all. Our CE said on 360/50 that their records showed only 10% would IPL after EPO pull. It was a heavy hit, shunting everything to ground. Thermistors and other protective circuits would trip. In a message dated 8/18/2014 10:44:11 A.M. Central Daylight Time, [email protected] writes:
of the processor EPO, although the IBM CE was always called in to check out the system afterwards. At least on some processor model (360/65?) , the beginning of the diagnostic procedure was to just reset the mechanical trip in the switch to reset the EPO switch, do a power-up and see if everything worked. My recollection is that after one EPO incident our in-house IBM CE did something to disable the EPO mechanical lockout on the processor EPO switch, so if the EPO were tripped when the CE was off-site and SysProgs got in before the CE he could advise them to reset it and try to power-up while he was in route. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
