7.  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 only when you intend to use the 
chassis intrusion detection feature.
•  Make sure to remove the cap on the EATX12V connector before connecting 
an 8-pin EPS +12V power plug.
•  Use only either a 4-pin ATX12V or an 8-pin EPS +12V power plug for the 
EATX12V connector.
