power glitch at 18:08 PDT
We experienced a power glitch at Jun 12 2014 01:08:29 UTC (18:08PDT). The lights in the control room flickered for several seconds, the MSR UPS reported a switch to battery and back. Vacuum controls was not affected. Here is what I have found:
All models on h1lsc0 and h1asc0 stopped running
Both mid station PEM systems have DAQ timing errors
Right hand monitors for workstations opsws0,1,2 went blank
I'm going to restart the affected models. The workstations were power cycled.
h1asc0 booted and came back with no problems.
I was unable to reboot h1lsc0 cleanly, I'll leave this until tomorrow, Jeff said it is not needed this evening.
both mid stations pem systems actually rebooted rather than freeze like asc/lsc. I tried restarting h1ioppemmy and could not clear the timing error. I'll leave both mid station pem systems for tomorrow.
