At around 11:30 local time, we shut down the Pcal lasers at both end stations.

Shutter controls were set to local and the shutters closed.

Laser power supplies were switched off and the keys removed.  Keys are in the Pcal tool zip-lock bags on the shelf in the Pcal pylon at each end station.

Laser power supply and AOM driver modules were switched off (two rocker switches on the back side of module).
