Validate Hot-Pluggability

Can the treadmill be hot-plugged? The use-case is to be able to install-and-remove the treadmill platform where the mechanical hardware, sensors, and brake are a single unit. This is currently going to be done with an electrical spring-based contact pins. We need to make sure every io pin (brake, encoder, transducer) can be unplugged or plugged-in with the device turned on without damaging anything.
