WP11508 Replace MSR Timing Master
H1 was brought into a safe state.
All models are being shutdown in preparation for replacing the MSR timing master. We are keeping h1susauxb123 going for as long as it and the DAQ can to maintain vacuum trends.
The spare timing master has been installed, all SFPs are green. Daniel reports timing system is green.
The DAQ restarted itself, looking ok now.
I hand started the susaux models, all looks good. We restarted the running susauxb123 models once it was no longer the only front end running.
We are now starting all of the models.
Old Unit S1103261
New Unit S1103262
All models running, SWWD have been untripped. DAQ is good.
Handing over to control room to recover the IFO.
H1 has been recovered and started observing as of 03:37 UTC.
