====== LVPS Trip monitoring in 2022 ======

From Stan:

LBA33 and EBC58. Both have troubles to start MB_side bricks - see
https://pcata007.cern.ch/elog/Maintenance/4980

  - In  LBA33 we saw HV and DIG bricks started but not MB bricks.
  - In  EBC58 all but Dig+5 bricks started.

 The ATLAS detector is already closed - we have no possibility
To replace LVPS until next shut down ( dec 2022)

|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 |
