ARRANGEMENT’S MOTIVATIONS 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 Y.28-16.A1 Turbine Heat exchanger TDI (main) Air deflector TDI (backup) ATCA shelf TTC crate Fan tray Patch panel Side A F/O box Patch panel Side C ARRANGEMENT’S MOTIVATIONS ATCA shelves easy to reach Space between ATCA shelf & TTC crate: to make the TTC fibers from ATCA back-side going to TTC crate front-side Space for 14U ATCA shelf instead of 2 6U shlves F/O box on top of Patch Panel: to not cross the cables going to the VME crates Patch panel: easy to reach position in the back, cables arising from the floor (to VME & from detector) do not cross the cables to ATCA Space above TDI: to possibly connect a keyboard and a screen? 2,31 m 1,15 m

Notes ATAC shelf supplies 1.5 kW comes with fans located on right and left sides to allow right-left air motion Ex: http://www.asis-pro.com/drupal-7.14/?q=node/4 If we intend to use the emulator in USA15 we have to swap 48 fibers Vertically cooled rack believed to be OK with this type of ATCA shelf No need for back-door with fans pc-csc-det-01 can remain in rack 29 with the ctrl network switch for the time being The Rack schema has to be entered into Rack Wizard

Another (Preferred) Solution TTC crate easy to be reached 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 Y.28-16.A1 Another (Preferred) Solution TTC crate easy to be reached CSC is not the only customer (DCS, potentially Micromegas) ATCA primary shelf not too low USA15 is not a lab Possible frequent disruption during LS1 on network, cooling, electrical distribution USA15 is not easy to reach and not a pleasant place to work ATLAS management would disagree No need for a second ATCA shelf for emulator Half RCEs can run as emulator if needed, and be connected to the other half using the patch-panel Turbine 2,31 m Heat exchanger ATCA shelf 1,65 m Heat exchanger F/O box Patch panel Side C Patch panel Side A TTC crate Fan tray Air deflector TDI (main) TDI (backup)

CERN TEST STANDs What we need to do Possible labs: Develop DCS interface People involved: George Requires: Shelf Manager + control network + DCS PC (aka running PVSS) Study IPMI interface with TDAQ sysadmins Develop TDAQ interfaces Develop CSC software Use an LTP if possible Possible labs: TDAQ Lab  OK for 2. and 3. maybe 1. as well (depends on PVSS availability and if George can get the account there) ? For 4. and maybe 1. We need: access to afs, to tdaq release, stable network, rack, external support SR1 is the best option as far as I can tell: need to ask for permission + think about cooling: are the embedded fans enough?

Shopping List Two (2) 2U ATCA Shelf + Shelf Manager for TDAQ Lab One (1) 6U ATCA Shelf + Shelf Manager for ?LAB? One (1) 6U ATCA Shelf + Shelf Manager for USA15 Boards? 
