Derek, to me those pictures look like it's an option 007 + option 085 configuration (high power measurements).This means no bias-Ts, and it will be a bit of work to convert to 4-sampler. This option also includes direct sampler access (opt. 012). You may or may not have option 89 (mixer / frq.offset measuremnts), I can't tell from the pictures.
The service switch setting should not stop the instrument from booting up. It's possible that you "fixed it" while moving things around, possily that pinched cable.
