Post Tues Maintenance LVEA Sweep

Ryan S and I did a sweep of the LVEA. Everything looked good, but there were a few things we thought were probably okay but still wanted to log:

attachment1 - Two power supply units were on at the y-arm termination slab.

Not pictured - Small puddle of condensation water on the tile close to y-arm termination slab from the pipes above. This water is separate from the puddles that collect from either side of the beam tube. - tagging VE

attachment2, attachment5 - OM2 power supply and multimeter connected to Beckoff Output Interface 1 via mini hook clips

attachment3 - Computer for PCal X plugged in. I remember talking to TJ and Tony about this last time I swept and the conclusion (I believe) being that it had been plugged in for someone who had needed it at the time (not sure if still needed?) - tagging CAL

attachment4 - Power supply underneath Hartmann table on

Olli, Ryan, thanks for noticing this computer by the Xend Pcal system.  While it happens to be located nearby, and we may have used it years ago, we (Pcal team) have not used that computer for some time and don't plan to use it in the future.  As far as I know it is currently in an inoperable state, having been replaced by the CDS laptops that we carry down to the end stations from the corner station.

Thanks Oli. The power supply under the HWS table remains on as it powers the HWS cameras. Moved from in rack power in 2018: 44948 44855.
