Well, it turns out the IFO is a complicated beast with a lot of underlying infrastructure that we rely on to even begin recovering the IFO. Since LHO so infrequently loses power, I summarize the IFO systems that are necessary before we can begin the alignment / recovery process with pointers to aLOGs and/or names of people who did the work, so that we have a global perspective on all of the worlds that need attention when all power dies. One could consider this a sort of check-list, so I've roughly prioritized the items into stages, where the items within each stage can be done in parallel if the man-power exists and/or is on-site.

Stage 1
--------------------
Facilities - Richard

Vacuum - John / Kyle / Gerardo

Stage 2
--------------------
CDS - 
     Work Stations - Richard
     Control Room FOMs - Operators / Carlos
     DC Power Supplies - Richard

Stage 3
--------------------
CDS continued
     Front-Ends and I/O Chassis - Dave (LHO aLOG 22694, LHO aLOG 22704)
         Timing System 
         Guardian Machine (comes up OK with a simple power cycle)
     Beckhoff PLCs - Patrick (LHO aLOG 22671)

PSL - Peter / Jason / Keita (LHO aLOG 22667, LHO aLOG 22674, LHO aLOG 22693)
     Laser
     Chillers
     Front Ends
     TwinCAT Beckhoff (separate from the rest of the IFO's Beckhoff)
     IO Rotation Stage

TCS Nutsinee / Elli (LHO aLOG 22675)
     Laser
     Chillers
     TCS Rotation Stage (run on same Beckhoff chassis as IO Rotation Stage, and some PSL PEM stuff too)

ALS Green Lasers - Keita
     The interlock for these lasers are on-top of the ISCT-Ends, and need a key turn as well as a "start" button push, so it's a definite trip to the end-station

PCAL Lasers - Sudarshan
     These either survived the power outtage, don't have an interlock, or can be reset remotely. I asked Sudarshan about the health of the PCAL lasers, and he was able to confirm goodness without leaving the control room.

High-Voltage - Richard McCarthy
     ESD Drivers, PZTs
     
HEPI Pumps and Pump Servos - Hugh (LHO aLOG 22679)

Stage 4
------------------
Cameras - Carlos
    PCAL Spot-position Cameras
    Green and IR cameras
     
SDF System - Betsy / Hugh
    Changing the default start-up SAFE.snap tables to OBSERVE.snap tables (LHO aLOG 22702)

Hardware Injections - Chris Biwer / Keith Riles / Dave Barker
    These have not yet been restarted

DMT / LDAS - Greg Mendell / Dan Moraru (LHO aLOG 22701)


May we have excercise this list very infrequently if at all in the future!
