[Jenne, MikeJ]
The ETMY oplev quad sum was ~0, so we went to investigate. The power supply was dead. Keying it on and off didn't fix things, and it was certainly getting power since the front indicator light was flickering. We replaced it with a different power supply, and the oplev is back.
Also, the Y-green AUX laser was off, presumably from the power outage a while back. I turned it back on.
EDIT JD: The first power supply we used didn't work....the oplev was on for a few minutes, then went off again. We switched to one of the new (still JDSU) power supplies from Edmund Optics, and it's been happily working for at least an hour now. |
