DCS - general

• Unscheduled power cut Wed. morning (08.02.2012, human error) – DCS (and HLT) off, due to UPS on bypass– In the middle of DB migration, had to start again. OK on Thursday.

• 48V consolidation tests on Fri. 17.02.2012– Switch off all DCS (timing to be defined)– Detector equipment (including gas and cooling) shall be in a state to

support power interruptions– Restart DCS in the afternoon: only new DCS cluster, except agreed

exceptions.– Some ‘restart issues’ might persist over the weekend (not all experts are

available on Friday)

DCS – migration status

• Phase II (all SW upgrades completed on old HW)– All done except for: AD0, PHS, SPD, SDD, MCH-GMS, LHC I/F

• All systems have been allocated new hardware• Migration to new hardware

– See table ( Done - Ongoing - Not started )

• Remarks– SPD will start ‘after drilling’– SDD will start 15.02– Gas will be done this week

DCS - plans

• DCS on-call started– Only for operation issues, not for support on migration

• Next week mornings: Integration sessions, – Integrating detector DCSes in central DCS, checking compatibility issues– Central operation tests
