Powering Up

3.9 Starting Up the First Time
1. After all connections are made, close the system case cover.
2. Be sure that all switches are off (in some systems, marked with
).
3. Connect the power supply cord into the power supply located on the
back of your system case according to your system user’s manual.
4. Connect the power cord into a power outlet that is equipped with a surge
protector.
5. You may then turn on your devices in the following order:
a. Your monitor
b. External SCSI devices (starting with the last device on the chain)
c. Your system power. For ATX power supplies, you need to switch on
the power supply as well as press the ATX power switch on the front
of the case.
6. The power LED on the front panel of the system case will light. For
ATX power supplies, the system LED will light when the ATX power
switch is pressed. The LED on the monitor may light up or switch be-
tween orange and green after the system’s if it complies with “green”
standards or if it has a power standby feature. The system will then run
power-on tests. While the tests are running, the BIOS will alarm beeps
or additional messages will appear on the screen. If you do not see any-
thing within 30 seconds from the time you turn on the power, the system
may have failed a power-on test. Recheck your jumper settings and con-
nections or call your retailer for assistance.
