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

7. Notes
ATAC shelf
supplies 1.5 kW
comes with fans located on right and left sides to allow right-left air motion
Ex:
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

8. 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

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

9. 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?

10. 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
