are designed to t these connectors in only one orientation. Find the proper
orientation and push down rmly until the connectors completely t.
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.
