LVPS Trip monitoring in 2015
| Module | Trip time | Symptom, problem found | DCS image |
| LBA47 | 2015-04-29 09:56:12 | NOT a real trip. Did TileMB test which turned off and then turned on the module https://atlasop.cern.ch/elisa/display/259446 | |
| LBA37 | 2015-04-28 13:33:51 | NOT a real trip. Power-cycled to verify deskew adjustment https://atlasop.cern.ch/elisa/display/259331 | |
| LBC12 | 2015-04-28 13:31:01 | NOT a real trip. Power-cycled to verify deskew adjustment https://atlasop.cern.ch/elisa/display/259331 | |
| LBA07 | 2015-04-28 13:30:11 | NOT a real trip. Power-cycled to verify deskew adjustment https://atlasop.cern.ch/elisa/display/259331 | |
| EBA19 | 2015-04-28 13:22:03 | NOT a real trip. Power-cycled to verify deskew adjustment https://atlasop.cern.ch/elisa/display/259331 | |
| LBC24 | 2015-04-28 13:16:51 | NOT a real trip. Power-cycled to verify deskew adjustment https://atlasop.cern.ch/elisa/display/259331 | |
| EBC62 | 2015-04-22 11:18:28 | NOT a real trip, EBC62 was power-cycled requested by DCS to fix timing jump (power-cycled https://atlasop.cern.ch/elisa/display/258617 ; timing jump https://atlasop.cern.ch/elisa/display/258618) | |
| LBC18 | 2015-04-22 11:19:31 | NOT a real trip. Power-cycled https://atlasop.cern.ch/elisa/display/258618 | |
| EBA08 | 2015-04-17 22:47:27 | Not a real trip, HV_830 tripped, restarted HV side https://atlasop.cern.ch/elisa/display/258168 | |
| EBA02 | 2015-04-16 15:19:54 | NOT a real trip, power-cycled to fix discarding events https://atlasop.cern.ch/elisa/display/257996 | |
| <fc #FF0000>EBC26</fc> | 2015-04-04 15:10:21 | REAL trip https://atlasop.cern.ch/elisa/display/256790 | |
| LBC03 | 2015-04-09 06:07:10 | Probably a real trip. No elog entry found | |
| LBC31 | 2015-04-03 10:01:31 | NOT a real trip, the module was due to discarding events and auto power-cycled many time. It was off at ~0:00 on April 3, 2015 https://atlasop.cern.ch/elisa/display/256633 and was switched on again ~13:00 on April 3, 2015 https://atlasop.cern.ch/elisa/display/256669. The problem was fixed by using 2nd readout fiber https://atlasop.cern.ch/elisa/display/256668 | |
| LBC31 | 2015-04-03 02:00:00 | NOT a real trip, the module was due to discarding events and auto power-cycled many time. It was off on ~0:00 on April 3, 2015 https://atlasop.cern.ch/elisa/display/256633 and was switched on again ~13:00 on April 3, 2015 https://atlasop.cern.ch/elisa/display/256669.

| LBC31 | 2015-04-02 21:01:49 | NOT a real trip, power-cycled to fix 100% discarding events https://atlasop.cern.ch/elisa/display/256626. It was switched off ~0:00 on April 03, 2015 https://atlasop.cern.ch/elisa/display/256633 | |
| LBC31 | 12:18:09 | Not sure it is real trip, but LBC31 experienced multiple auto power cycle during 2014-04-02 until it turned off https://atlasop.cern.ch/elisa/display/256633 | |
| LBC31 | 2015-04-02 00:59:29 | NOT a real trip, power-cycled to fix 99% discarding events https://atlasop.cern.ch/elisa/display/256502 | |
| EBA11 | 2015-03-31 23:35:39 | Power cycled https://atlasop.cern.ch/elisa/display/256382 | |
| LBC11 | 2015-03-31 10:22:27 | Seem to be power cycled after this “LBC11 seems to be off (at least the ROD link is off). [Run #259427 LB #51]” https://atlasop.cern.ch/elisa/display/256329, two day later report showed it was power recycled frequently https://atlasop.cern.ch/elisa/display/256504 | |
| EBC10 | 2015-03-25 11:57:07 | real trip https://atlasop.cern.ch/elisa/display/255607 | |
| EBC25 | 2015-03-25 01:45:56 | Power cycled due to lost CAN-bus communication https://atlasop.cern.ch/elisa/display/255559 | |
| EBC26 | 2015-03-19 08:08:17 | Real trip https://atlasop.cern.ch/elisa/display/254713 | |
| EBC10 | 2015-03-13 23:18:49 | real trip https://atlasop.cern.ch/elisa/display/254196 | |
| LBC20 | 2015-03-11 10:14:45 | ||
| EBC56 | 2015-03-10 13:23:45 | ||
| LBA47 | 2015-03-09 16:00:02 | ||
| LBA05 | 2015-03-06 12:56:09 | Not found elog for this trip but later on 3/15 this modules discarded events (67%) and was power recycled by that (https://atlasop.cern.ch/elisa/display/254185). It could be that this trip was because of power-cycled by the same reason |
