STATE of H1: Preventive Maintenance
SHIFT SUMMARY:

Fairly light Maintenance.  Did have some issues with the BSC1 SEI power supply swap (IO Chassis needed to be swapped instead of what was planned and an additional power supply in rack was swapped as well).  Handing over H1 to Camilla as we get to MAX POWER for Elenna to do checks on the laser after today's PSL work.
