1. A software version control method comprising: installing a software configurable component on an aircraft; automatically setting a listen switch of the software configurable component to an on state upon installation of the software configurable component in a new installation location, wherein the software configurable component does not command power outputs to a configuration manager on a power path while the listen switch is in the on state and wherein automatically setting the listen switch of the software configurable component to an on state comprises: reading a radio frequency identification (RFID) tag associated with the installation location to obtain a location tag value; comparing a previously read tag value with the location tag value; and setting the listen switch to the on state if the previously read tag value does not match the location tag value; manually setting the listen switch to an on state if no previous tag value has been read by the software configurable component; listening for a software version from the configuration manager on a communication bus; turning off the listen switch if a software version of the software configurable component matches the software version of the configuration manager; and downloading an updated software version to the software configurable component if the software version of the software configurable component does not match the software version of the configuration manager.
