5. Chassis intrusion connector (4-1 pin CHASSIS)
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.
By default, the pins labeled “Chassis Signal” and “Ground” are shorted with
a jumper cap. Remove the jumper caps only when you intend to use the
chassis intrusion detection feature.
