Resetting CB's
Are you asking about "Resetting" or "Cycling" a system CB? Thinking as one replaced by computers I would suggest that whilst still safely on the ground, and if unsure of the effect of "cycling" a CB, it would probably be prudent to get on the radio to the technicians for advice. The pertininent words in the offering from nncO are "ALMOST all computers can be reset".
Reset Switchs and CBs are different. Reset Switchs give Tech crew the facility to try and erase erronious messages. Circuit Breakers are used as a function of maintenance and should NOT be touched by Tech crew. To me it seems fairly obvious. If the tech crew can not erase a message within the scope of the FCOM, then bring it back to blox. That is why we have maintenance divsions.
