6. Chassis intrusion jumper (4-1 pin CHASSIS1)
This connector 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.
Move the jumper cap to pins 1-2 when you intend to use the chassis intrusion
detection feature.
