I noticed when I came into the morning meeting that the laser had tripped out.  It was on earlier today.  The most likely cause
was that it tripped because I inserted the reference cavity heater card into the Eurocard chassis and made the connection to the
temperature sensor box that's on the PSL table.

In starting the laser up, I could not open the external shutter from the diode room.  The Beckhoff computer indicated there was
an EPICS alarm.  Went to the control room and hit the control room reset button on the laser script.  Went back to the diode room
to open the shutter - which worked.  By the time I got back to the control room, all the servos were locked.

A note in passing, I have to check with Dave Barker to see if this is how the shutter is meant to behave after changing the to
RCG 2.8.5.  It certainly was easier to recover from than the power outage the other week.
