Safety and electrical systems Evacuation 20 PX 24 fire detect. UPS Auto-transfert Evacuation UX 25 fire detect. + red phones SNIFFER mainten. DSS Evacuation Early morning/late evening (tbc) UPS AUG 26/11/10 ALICE planning meeting. DSO 13

Safety and electrical systems Impact on ALICE • EN/EL: interruption on auto-transfert network (9/12 from 07: 00 till 07: 05): – All 'normal power‘ will be cut for 5 minutes: wall outlets, non-UPS in the ACR, SXL 2, non-UPS power for the cooling plants, gas systems – It will not affect the 'machine network‘ (all racks will remain powered (part of the 'EXD', machine, network) – This network also provides the power to the UPSes, so they will run on battery for the time of this cut – See https: //edms. cern. ch/file/1106913/1/ENNC_2010_196. pdf • EN/EL: AUG Test (20/1) (Arrêt Urgence General – General Emergency Stop) – Major electrical perturbation. Also ACR affected • DSS modification (13/1) – Will stop the full DSS, trigger all interlocks, including stopping power to all racks • LHC evacuation tests (7/12 after 18: 00 and 24/12 tbc) – no access UX 25 26/11/10 ALICE planning meeting 14

DAQ upgrade plans • 21 st Dec PM till the 04 th Jan included – The DAQ will be OFF during the CERN closure. – The ACR PCs will be left ON to give access to the DCS for the detectors teams who need it. • 5 th to the 11 th of January included – The DAQ will be switched ON with the present version of all software to allow a quick commissioning after the installation of new detector modules or the intervention on existing detectors. • 12 th to the 23 rd Jan included – The DAQ will be OFF during the cooling interruption at P 2. – This period will be used by the DAQ team for a major hardware reshuffling (addition of LDCs, replacement of several servers) and a major software upgrade (transition from Linux SLC 4 32 bits to SLC 5 64 bits). • 24 th January – The DAQ will be ON again. It will run under SLC 5 64 bits unless there would be an unexpected key problem. • The electronic logbook will remain available during the whole period. 26/11/10 ALICE planning meeting 15 Pierre/Uli

DCS plans • Baseline: DCS will be operational all times where technically possible – With ‘best effort’ support – With access restrictions during CERN End-of-Year closure (22/12 – 4/1) • Many activities and upgrades are planned – Will be coordinated with individual detectors to minimise impact – For central systems, as much as possible in shadow of other perturbations (e. g. cooling stop) – Perturbations (e. g. for reboots etc. ) cannot be excluded • Detectors are invited to communicate ‘critical periods’, with services needed – Will try to cater for detector needs as much as possible • Known perturbations: – Tue 7/12 10: 00 – 12: 00, interruptions of the GPN link to/from P 2 • Upgrade of router, test impact on ALICE – Wk 50 (13 -17/12) – major updates to all PC (many perturbations to be expected) – 12/1 – 21/1 (cooling stop), only minimal central services. All detector DCS switched off, except for special requests and if cooling power allows • More detailed planning at weekly and daily meetings 26/11/10 ALICE planning meeting 16 André / Peter
