I had to key the c1psl crate to get the PMC locking again. Without this, it would still sort of lock, but it was very hard to turn on the loop; it would push itself off the fringe. So probably it was stuck in some state with the gain wrong. Since the RF stuff is now done in a separate electronics chain, I don't think the RF phase can be changed by this. Probably the sliders are just not effective until power cycling.

Once the RT machines were back, we launched only the five IOPs. They had bunch of red lights, but we continued to run essential models for the IFO. SOme of the lights were fixed by "global diag reset" and "mxstream restart".

The suspension were damped. We could restore the IMC lock. The locking became OK and the IMC was aligned. The REFL spot came back.

At least, I could confirm that the WFS ASC signals were not transmitted to c1mcs. There must be some disconneted links of IPC.

I then tried to get the MC WFS back, but running rtcds restart --all would make some of the computers hang. For c1ioo I had to push the reset button on the computer and then did 'rtcds start --all' after it came up. Still missing IPC connections.

I'm going to get in touch with Rolf.
