These are the best contacts I know of (and the contacts are the most crucial feature of course) Used (equivalent D connector) in STAR, excellent results Is 11mm height too much? Plastic dummy in fab now at IU Received first parts, test assembled.

SCROD connector board locking mezzanine connectors clk/data cable(s), e.g. ultraflat cat 7 ?? strain relief Similar technology was used at IU for STAR SSD That case was larger (taller) but it can be shorter and smaller with the right cable for iTOP The solder post terminals seen here were necessary because it was aluminum wire cable, very fragile. We can solder direct to PCB for iTOP Strain relief block custom fitted to cable shape. (Or can pour epoxy for strain relief.) Making the clock/data cable connection with Low height Proper strain relief on cable Small footprint on SCROD

Slide 9

Real cable that you can buy from someplace other than amazon.com / no-spec asian import. With a real spec, including a UL approval. VW-1 should be good enough for the short pigtail connections. Anyway we have to deal with it for the power wires too. At worst, in suitable flame-retardant sleeving it should be approvable. I dont have this yet, so I dont know about flexibility. But it is probably similar to the Fosmon brand cat7 I have, which is pretty nice on flexibility. Termination may be tedious.

OLD SLIDES / BACKUP

Slide 11

Power supplies selection/evaluation Wiener ordered one module; ships from factory 12/23, ETA IU week of 1/5 Andreas Ruben will travel to IU to setup, and discuss requirements etc. Keysight i.e. HP Matt shipped 2 nd unit here; examined but not powered yet Excelsys Cost is such as to merit serious consideration Will sketch out what I think would be a good design around these, and cost it Matt has sent 2 Xg3 power modules (the ones wed use) and 6-slot mainframe (not exactly the one wed use but close enough for evaluation). The setup (Too) Heavy cables found for basic preliminary evaluation of supplies with 0.5V drop restriction Bought 12AWG cable for test (Belden #5000FE, 2C 12AWG + foil shield) Sense cable found I think (have to get permission to borrow) 200VAC power source found, 100VAC also possible (both 60Hz though but should be ok); will start with 208VAC for simplicity IU iTOP cables/power/cooling update 12/22/2014 also see other slides on cooling G.

SCROD cables Have some super-limp flexible wire (1.8m, 16AWG & 20AWG) samples from Jaguar Industries. Also some decent (tougher but less limp) wire from Polar Wire Inc. Breaking news just received from Jaguar 1000ft 16AWG white, ordered last Wednesday (see next slide) Patch connectors See following slides External power cables Urgently need info on cross-section constraints (Est.
