13. 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 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, the pin labeled “Chassis Signal” and “Ground” are shorted with
jumper caps. Remove the jumper caps only when you intend to use the
chassis intrusion detection feature.
