12. 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.
