QUICK SUMMARY:

After Erik replaced the HAM2 DAQ.
There was a timing error on another chassis h1sus2b,  which required a restart. see Eriks alog.

I then put all the Optics in safe mode to restart that chassis & reset the ISI and HPI watchdogs.
There was a DAC Kill i also had to reset to reset the ISI and HPI watchdogs.
We are now trying to get an initial alignment in. But the IMC is not locking. This may be due to the fact that the IMC is in the HAM  that tripped this morning.
Taking ISC_LOCK to IDLE

Trending the Sliders back before the earthquake for the IMC.
Camilla and I touched up MC1, MC3, PRM, IM2, IM4  back to the slider values before the tripped chassis and recovery and IM3 see Camilla's Alog.

Jason and Jenne went into the PSL room to adjust the ASL_FC2. When they came out Jenne said that an ASL adjustment at End X was next.
