After powering up the FMy satellite boxes and checking that the EE on the outside of the chamber were functioning properly (thanks, Richard), I went in the chamber to look at the in-vacu stuff.  Indeed, the cable that needed an end-to-end swap before the holiday break, had not finished making it to it's connecting octopus cable.  When I tried to seat it, I found that the 225 cable needed helicoils, preventing good connection.  We're hunting tools now to finish helicoiling these (all 3 225 cables need the helicoils) connectors.
