Now that we have a better handle on how much rack space the SPI pathfinder will take from making it fully functional in the optics lab (see LHO:89269) I've uploaded a new version of the rack layout design to G2401479-v3 -- a copy of which is attached here for convenience.

Then, with this in hand, I went out to SUS-R2 and:
    - Finally removed all evidence of the iLIGO style U-height labeling, 
    - Re-labeled the rack in the standard 42U rack convention with super large font for ease of reading, and
    - installed rack screws in all locations where the SPI chassis will need them.

The first two pics show BEFORE (labeled with counting starting at the top) vs. AFTER (labeled with counting starting at the bottom). In this modern convention, forced on this old rack, u-height "1" is missing; true for all of these racks (e.g. true SUS-R1 as well; see LHO:83156).
The last pic shows U18 thru U2 with all the rack screws and sockets prepped.

I'm in the process of feeding this info back to Dean so he can update the Altium version of the SPI wiring diagram D2400111.
