The board supports the chassis intrusion detection function. Connect the chassis intrusion
sensor cable from the chassis to this connector. When the system’s power is on and a chassis
intrusion occurred, an alarm will sound. When the system’s power is off and a chassis intrusion
occurred, the alarm will sound only when the system restarts.
