ASUS A7N8X motherboard user guide

3.1 Starting up for the first time
1. After making all the connections, replace the system case cover.
2. Be sure that all switches are off.
3. Connect the power cord to the power connector at the back of the
system chassis.
4. Connect the power cord to a power outlet that is equipped with a surge
protector.
5. Turn on the devices in the following order:
a. Monitor
b. External SCSI devices (starting with the last device on the chain)
c. System power (if you are using an ATX power supply, you need to
switch on the power supply as well as press the ATX power switch
on the front of the chassis).
6. After applying power, the power LED on the system front panel case
lights up. For ATX power supplies, the system LED lights up when you
press the ATX power switch. If your monitor complies with “green”
standards or if it has a “power standby” feature, the monitor LED may
light up or switch between orange and green after the system LED
turns on. The system then runs the power-on tests. While the tests are
running, the BIOS beeps or additional messages appear on the
screen. If you do not see anything within 30 seconds from the time you
turned on the power, the system may have failed a power-on test.
Check the jumper settings and connections or call your retailer for
assistance.
