14. 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 pin labeled “Chassis Signal” and “Ground” are shorted with a jumper
cap. Remove the jumper caps and enable the related options in BIOS if you intend to
use the chassis intrusion detection feature.
A message appears when you connect the sensor or switch at the rst time or when you
reconnect the sensor or switch to this connector. Reset the system to exit the message.
