Daily reports

Friday 26/10

We have the electronics and computers setup and GISMO is on the pump. IRAM left the electronics in the cabin which gave us a head start. We also decided to put the cabling above the floor (with a good metal cover) to reduce the chances of breaking thermometry cables while fishing cables and also to make setup/teardown easier. We also cleaned up the IRIG isolation cabling and put the isolator box in the rack. The server was a little stubborn to boot but eventually gave in. The server, client, crate, IRIG, are up and running. We also made some fresh clones of the server disk and tested the backup server (booted and started GISMO software). Created wire cover.
