• 8:00 - 18:00: UX25 cavern in Restricted mode– No access UX25 (except Transport, VAC and TC)

• From 18:00 - Cavern in General mode

• Interruption on auto-transfert network (from 07:00 till 07:05). No access underground

– all wall outlets will be interrupted– including all non-UPS outlets in the ACR (so essentially all WRs)– including outlets SXL2, offices and barracks– non-UPS power for the detector cooling plants will be interrupted– power to all gas systems will be interrupted– the UPS powered systems will not be affected, but will run on batteries for the 2 min.

interruption– the electronics racks in the cavern and CRs will not be affected.

DCS plans• Wk 49

– Tue 7/12 10:00 – 12:00: interruptions of the GPN link to/from P2• No connectivity on GPN (mail on laptops etc.); could have impact on running

systems (is the main reason for this test: try to spot dependencies)• Done – switch upgraded to 10x higher bandwidth; experienced blockage of

DCS; to be investigated more tests needed later.– Wed 8/12 – Fri 10/12 (daytime): SW upgrades and patches to central

systems, to detectors on request only (Operating system and PVSS)• Systems unavailable for short (~hrs) periods, frequent reboots
