So unplugging all motor power and encoder cables will allow us to separate the electronics from the frame cleanly.

Just so you know... If a jaguar in a daisy chain fails, down stream jags are
NOT affected. The contacts on the PCB are wired through (in to out) without going through active components.
The only exception to the rule is in the case where you are using the Jaguar as an RS232 to CAN bridge... Since that jaguar is actively translating commands, if it fails, the link fails. But again, any other Jag in the chain can lose power and everything will keep operating as it should.
Test it out for yourself - we did.
