3. Old DU1 Studies
Situation: several DOMs (1,2,6,12) do occasionally not boot after having been powered for some time
Origin : these DOMs are not powered
power spike after 20msec  shutdown BOB
DOM 6 opened, various tests
BOBs of DOM 1,2,6,12 also opened
Now everything works , i.e. impossible to reproduce non-boot condition

4. White Rabbit switches
Spring 2016 : no bridge any more, GPS directly connected to GM broadcast switch
Very rare boots needed
Problems after boot (Aug 2016, Jan 2017)
No PTP packets on broadcast port 18
Solved by adding a 5sec delay into startup script before disabling auto-negotiating for port 18 (wr17)
