Long distance cable installation status

1. Calorimeter commissioning meeting Long distance cable installation status V. Bobillier

2. Calorimeter commissioning meeting • Agenda • Cable trays status • Rack installation • Status • Missing information (rack layout) • Long distance links • Status • Planning • Missing information (cable allowance) • Missing material (connectors and PP) • Tests foreseen • From sub-det to PP rack cabling • What is foreseen (reminder) • Possible manpower issue V. Bobillier

3. Calorimeter commissioning meeting • Cable trays installation status • All long distance cable trays installed. • Few additional cable trays in the Velo region still under installation. • Cable trays to go from PP to Fixed Point for Calo and Muon still to be installed. V. Bobillier

4. Calorimeter commissioning meeting • Racks installation status • TELL1 racks in Counting House : • TELL1 crates under installation when received at pit 8. • All patch panels, heat exchangers, deflectors and turbines are installed. • Remaining task : • - Prepare patch cord cable installation in the rear of the TELL1 boards (can start when TELL1 are there). • - Test of crate power and control (CAN interface). • - Installation and test of TELL1 interfaces (ECS, DAQ, TTC). • REMINDER : Optical patch cords are responsibility of sub-detectors. • (OT: late change) • All other racks (in counting house – D3B03 to D3B05) : • All the mechanics still to be done (installation of sliding bars, turbine, heat exchangers, deflectors, side plates, etc). • Information on rack layout is urgently required for that. V. Bobillier

5. Calorimeter commissioning meeting D3B03-05 racks in Counting House • For the moment, these racks look like this : • No side plates for air flow • No internal support for cables • No sliding bars • No heat exchangers • No flexible cooling pipes connecting HE • No deflectors • Already a turbine with rack monitoring and control (as we receive them and there is no much choice where to install them) • Power distribution box installed. • Goal: Have the racks prepared as much as possible so it can be nearly “plug and play” to install your equipment. • If information is not received well in advance we will not be able to prepare your racks mechanically ! • Planning: We need to know when you plan to come to pit 8 with the first equipment ? • Significant mechanical work still to be done in all other non-TELL1 racks (HV, LV and other equipments). • Sub-detectors must: • Define the rack layout in rackwizard. • Buy required equipment (deflector, heat exchangers, etc if standard recuperated ones are not ok). • Rack internal cabling must be defined (equipment size, front/rear connection, air flow and other constraints must be taken into account). V. Bobillier

6. Calorimeter commissioning meeting Q2A01 patch panel rack in cavern • The following items are now being installed in patch panel racks : • ECS patch panels (SPECS) • LVPS (both pwr and ctrl) • DSS patch panels • Those patch panels are connectorized NOW •  This means no change in position will be possible afterwards ! V. Bobillier

7. Calorimeter commissioning meeting • Long distance links (from patch panels to counting house) current status • What has been done for the Calo: • All copper cables : pulled • Connector installation (LVPS and SPECS, PP side) : installed • Connector installation (LVPS ctrl, CH side) : installed • Remaining main tasks for the Calo : • Reaming connector installation (All HV, SPECS CH side + others) • Tests of all copper cables • Installation and test of all optical fiber cables V. Bobillier

8. Calorimeter commissioning meeting • Long distance links (from counting house to PP) missing information • HV Connectivity layout • HV patch panels and connectors • Optical fiber connectivity layout • Rack layout for D3B03-05. • To do: • Enter final rack layout (with all equipments) in rackwizard. • Enter all optical fiber connectivity layout (both ends) using rackwizard (good and reactive support is now provided by Dirk Wiedner). • Make very clear cable drawings for sub-detector specific links (mainly HV, good example can be seen here https://edms.cern.ch/nav/EDA-01313). • Provide HV and other specific patch panels and connectors. V. Bobillier

9. In Technical board yesterday • Long distance links (from counting house to PP) missing information • Deadlines • For all: Final rack layout ASAP • Calorimeter : - HV Connectivity layout Oct. 25 (mid next week) - HV patch panels and connectors Same • - Optical fiber connectivity layout End Oct. (31.10) • Muon : - All connectivity layout for Muon S1 Oct. 27 (end next week) - Optical fiber connectivity layout (except for L0 trig) End Oct. (31.10) • - HV connectivity layout Oct. 27 (end next week) - HV patch panels and connectors Same • Outer tracker : - All connectivity layout (optical fibers included) Nov. 6 (copper), End Oct. (fibers) • Silicon tracker : - All connectivity layout (optical fibers included) Nov. 13 (copper), End Oct. (fibers) • - HV patch panels and connectors Nov. 13 • Rich : - All connectivity layout (optical fibers included) Nov. 27 (copper), End Oct. (fibers) - HV patch panels and connectors Nov. 27 • VELO/Pile up : - All connectivity layout (optical fibers included) Dec. 11 (copper), End Oct. (fibers) - Analog link cables ??? (cable delivery, (start/end point for LV needed ASAP) connectorized or not ?) V. Bobillier

11. Calorimeter commissioning meeting • Long distance links (from CH to PP) cable tests • Copper cables: • - Continuity and short tests (at LV) will be made on all cables • No HV tests • No cross-talk, bandwidth or other similar kind of tests • Optical fiber links: • - Total power loss (dB) measurement • No OTDR tests • REMINDER : All link users must be capable of performing BER test with GOL. V. Bobillier

12. Calorimeter commissioning meeting • Patch cord cables (in CH and from sub-det to PP) • In CH : only optical fiber patch cords (MPO). • From sub-det to PP all cable types (readout, power, control, DSS, etc.) • REMINDER “Who is responsible for what” : • Cable ordering: Sub-detectors • Cable installation: Sub-detectors with help from CERN (to be discussed case by case in more detail). • Connectors: Sub-detectors with help from CERN (to be discussed in more detail). • Exception : TELL1 and UKL1 boards: sub-detectors only have to take care of MPO patch cords (input of TELL1). Other patch cords in TELL1 racks are installed by CERN. • Tests of DAQ, ECS and TTC links to TELL1s will be done by Online. • Tests for these links for UKL1 can only be done by online if soft is compatible (see with online if not). • REMINDER: Particular care must be taken with optical fiber cables and connectors ! V. Bobillier

13. Calorimeter commissioning meeting • Patch cord cables (in CH and from PP to sub-det) • Who does what: • Rich: Cabling done by themselves • OT: Same • Calorimeter: Help from CERN needed (until FP, to be discussed more in detail) • Muon: Not well defined yet. • ST: Help from CERN needed (to be discussed more in detail) • Velo: Help from CERN needed (to be discussed more in detail) • Further discussions are needed with sub-detectors requiring help for installation ! • Russian cabling team will be 100% occupied with long distance links until end of January at least. •  Hiring of temporary labor should be envisaged when needed for this cabling part. • This will be organized centrally • Cabling people to be supervised by sub-detector groups V. Bobillier

14. Calorimeter commissioning meeting Conclusion • Very simple conclusion : • Use rackwizard to enter all information concerning your rack layout and cabling. • Make precise drawing of specific cables (with explanations when particular care must be taken) • Get the connectors (and special tools when needed) for long distance links to pit 8. • If all this is not done very soon we will be blocked at some point with our Russian team playing cards at pit 8 !!! If we do not have information on time, racks and cables might look like that when you come at pit 8 with your equipment…! V. Bobillier
