15. 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.
