Summary of Conversion from SUSB123 & SUSH34 to SUSB13 & SUSB2H34 ('No QOSEMs/BBSS' Configuration)

Here is the summary with all the relavant alogs for the conversion from SUSB123 and SUSH34 to SUSB13 and SUSB2H34*.

*Our current configuration, specifically for SUSB2H34, is an interim state ("No QOSEMs/BBSS" config) on the way to the final O5 configuration, so SUSB2H34 doesn't fully match the cabling diagrams seen in D2300383. We can't fully upgrade to this O5 version yet because we don't have the BBSS, LO1, or LO2 installed yet, and need to be able to actuate the BSFM for the February commissioning period. To see what still needs to be done to get from this interim period to the final O5 configuration, see 88860 and google slides.
