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.
