3. Chassis intrusion header (4-1 pin_CHASSIS)
This header is for a chassis-mounted intrusion detection sensor or switch.
Connect one end of the chassis intrusion sensor or switch cable to this
connector. The chassis intrusion sensor or switch sends a low-level signal
to this connector when a chassis component is installed. The signal is then
generated as a chassis intrusion event.
