8. Power connectors (24-pin EATXPWR, 8-pin EATX12V, 4-pin EZ_PLUG1)
These connectors are for ATX power supply plugs. The power supply plugs
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 pins 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 connect the 8-pin ATX +12V power plug when installing two
CPUs.
• You can either use the 4-pin +12V power plug or 8-pin ATX +12V power
plug when installing only one CPU.
