C laser made (almost?) no power during the TMG test this morning. But there's no indication of it showing a problem afterwards; Ops kept using the laser successfully.
Causes to rule out:
1. No FSD trip
2. Amplifier output power fine
3. PSS shutters and fast MPS shutter read back as open

Not sure about the cause yet, will keep looking.

In concurrence with DC Power. Reset the fault at the interlock chassis, then on EPICS. Brought Arc 9 back up. Will cycle the stack twice, then cycle the trims. Then after a quick orbit check, we'll send back to the halls.
