Rich M, Richard, Dave Between the times 11:11 and 11:22 local I power cycled the h1seih16 front end and IO Chassis as part of the investigation of the intermittent 0.5Hz noise on HAM6 ISI CPS. The procedure followed was: in MSR Kill all user models and then the IOP model remove unit from Dolphin fabric power off the CPU from the console in CER power down h1seih16 IO Chassis using front panel switch remove 24V power cord for about 15 seconds reapply 24V power cord power up IO Chassis using front panel switch, verify timing slave start correctly in MSR power up h1seih16 CPU, verify no error on console
