Chassis intrusion connector (4-1 pin JCI1)
This connector is for a chassis intrusion switch cable. Connect one end of the chassis intrusion 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. By default, both pins do not have JCI1 connector connected.
