late afternoon, early evening today we powered down several CDS systems in preparation for tomorrow's power outage.

First systems to be powered down were backup servers and DMT. At 18:00 we started powering down the front end systems, leaving EY until last to allow ongoing commissioning work. By 19:00 all front ends were powered down except h1psl0. We initially stopped all the PSL models, but were unsure if we should leave the PSL overnight in this state. We therefore restarted the models, which closed the shutter in the diode room. We left the PSL in this shuttered state.

I ran the "make installWorld" to install the 2.8.5 front end code into the target areas, when the frontends are powered up tomorrow they will have the new version. I moved the 2.8.5 version of H1.ipc into position.

We powered down the DTS system in the H2 building.

Most control room workstations (leaving the vacuum monitoring machines), all wall mounted mac-minis, TVs and projector were powered off.
