The last 24 hours have been pretty eventful:
- DAQ problems on Sun. morning: lost ~40 minutes trying to restart VNC. ended up temporarily running the DAQ w/o the VNC
- Calorimeter HV problems starting ~16:30: lost 4.5 hours trying to replace the defective CAEN PS with the spare. This includes wrestling with EPICS and dealing with non-functioning channels in the crate.
- SHMS drift chamber problems: started ~03:00 this morning. not noticed/detected/reported until the morning! grouping of missing/low channel suggests low voltage, card origin. Currently in controlled access (Ellen, Heidi), trying to recycle power on the LV supplies.

Let's have an RC meeting today at 11:00 AM EST.
