9. ATX power connectors (24-pin EATXPWR, 4-pin EATX12V)

These connectors are for ATX power supply plugs. The power supply plugs

are designed to fit these connectors in only one orientation. Find the proper

orientation and push down firmly until the connectors completely fit.

8. 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.
