A system may be configured to provide a main body, configured to house a plugin card, and a card connector, including a first printed circuit board (PCB) having a backplane configured to electrically couple to the plugin card, a third PCB having a plurality of ruggedized connectors configured to couple to an external system, and a second PCB interposed between the first and third PCBs. The processor may be mounted on the second PCB and may determine a state of at least a portion of the system based on a sensor output, an input signal and/or an output signal, and an internal data value. The state may comprise at least one of operational, less than operational, tampered, needing maintenance, needing repair, and not working. And the determination may be performed via one or more criteria being satisfied.
