Quick Installation Guide
6. ATX Power On/Off Switch
Attach the 2-pin momentary type switch to the PWRBT connector for
turning On or Off your ATX power supply.
Step 8. External Peripherals Connections
External devices such as the keyboard, printer, PS/2 mouse,
modem, USB can be connected to the motherboard. Normally, you
can not plug your devices directly onto the motherboard, except for
the keyboard that plugs directly into the back panel KB connector.
For other serial (PRT1) and parallel devices (COM1, COM2), first
install the external connectors that come with your motherboard on
the computer case, then plug the other end of the flat cable to their
respective connectors.
Only after you have fixed and locked the motherboard and external
connectors to the computer case can you start connecting the
external peripheral devices.
When connecting an external device, use the following figure to
locate and identify which back panel connector to plug the device or
flat cable to.
