IOC is iochacp - might need to reboot from the hall.
No longer connected to terminal server. Can only reboot using remote power strip.
hareboot4. Outlet 4
Before rebooting, make sure the cavity locking/unlocking script is OFF.
After rebooting, the quarter wave plate and half wave plate will probably be set incorrectly. Also, some power meter calibration factors need to be updated and the feedback parameters updated.

Initialize the QWP and HWP
Needs updating
- Send wave plates to 0 degrees
- caput COMPTON_ORX_bo 1
