3. Chassis Intrusion header (4-1 pin CHASSIS)
The Chassis Intrusion 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
high-level signal to this connector when a chassis component is removed or
replaced. The signal is then generated as a chassis intrusion event.
