Disassembly of SM-II

Cooling problems in L5 short silicone hoses, bends problem has been solved in the mean-time 6 ORI links without power L5S4B worked when checked in clean room, no reason found L4S4A/B, L2S3A/B links had broken fibers, reason for failure not known L2S0A had bad connection in patch-panel DCS Board boot failure (L5S2) serial console output indicated error in root file-system reprogramming via JTAG did not work, probably due to broken flash return DCS board to Dirk for further testing New problem: Power Distribution Box channel L5S3 broken problem first occured during disassembly use alternate one for reassembly, repair in Heidelberg

SM-I known problems

5 ROCs with SCSN problems (broken MCM/VR?) electronics repair and tests necessary some simple tests possible during disassembly repair and additional tests should be done in Frankfurt/GSI power bus bar sensing ORI power
