Chapter 2
2.4 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
6. After applying power, the system power LED on the system front panel case lights up.
For systems with ATX power supplies, the system LED lights up when you press the
ATX power button. If your monitor complies with the “green” standards or if it has a
“power standby” feature, the monitor LED may light up or change from orange to green
after the system LED turns on.
The system then runs the power-on self tests or POST. While the tests are running, the
BIOS beeps (refer to the BIOS beep codes table below) 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.
7. At power on, hold down the key to enter the BIOS Setup. Follow the
instructions in Chapter 3.

2.5 Turning off the computer

on sleep mode or soft-off mode, depending on the BIOS setting. Pressing the power switch
for more than four seconds lets the system enter the soft-off mode regardless of the BIOS
setting.
