White coats and sallow faces...

After lunch we went over to the ICL to replace batteries in the computer shelfs ("racks").

Ralf, Carlos and me investigating the rack while Martin 
is taking the picture and Sven ran away (joke!). 

But at the very first try to plug the new 170 pound heavy thing in to the Power supply we heard a scary "buff" and the rack went down. It took us some time and sweat in our nice white or blue coats but we finally fixed it and could go on with the others. Hope we wont see this again. Detector works fine again.
