Power glitch 16:27 PST, DAQ CRC errors on h1susey
We had a power glitch which caused light to flicker at work and at my home on the other side of Kennewick. The only thing we could find in CDS was a single DAQ CRC error from h1susey to DC1 (DC0's data was not impacted).
There were no IPC errors.
I have cleared the CRC error and emailed LDAS to use FW0's frames when frame mismatches are seen at this time.
Neither UPS units reported any power issues at the time. Also I was unable to see any problems looking at the fast mains monitor signals in the corner and EX.
