7. Support Front Panel Connector
6. Connecting ATX Power Connector
This motherboard comes with a 20-pin and 4-pin ATX power connector. Make sure you plug
in the right direction. We strongly recommend you to connect the 4-pin 12V ATX connector
before connecting the 20-pin ATX power connector and use standard power supply.
Attach the power LED, speaker, and reset switch connectors to
the corresponding pins. If you enable “Suspend Mode” item in
BIOS Setup, the ACPI & Power LED will keep flashing while the
system is in suspend mode.
Locate the power switch cable from your ATX housing. It is 2-pin
female connector from the housing front panel. Plug this
connector to the soft-power switch connector marked
SPWR
.
9. Connecting IEEE 1394 Connectors (for MK89-1394)
With AGERE FW323 onboard, the IEEE 1394 provides data transfer rate up to 400Mb/s, and
USB1.0/1.1 just has 12Mbps. Therefore, the IEEE 1394 interface can connect with the
devices that need high data transferring performance, such as digital camera, scanner or
other IEEE 1394 devices. Please use the proper cable to connect with devices.

8. Connecting Front Audio Connector
If the housing has been designed with an audio port on the front panel, you’ll be able to
connect onboard audio to front panel through this connector. By the way, please remove 5-6
and 9-10 jumper caps from the Front Audio Connector before connecting the cable. Please
do not remove these 5-6 and 9-10 yellow jumper caps if there’s no audio port on the front
panel.
