Chapter 4: Starting Up
1. After making all the connections, replace the system case cover.
2. Be sure that all switches are off (in some systems, marked with
).
3. Connect the power cord to the power supply located 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 (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 chassis.)
6. The power LED on the front panel of the system case lights up.
For ATX power supplies, the system LED lights up when you press
the ATX power switch. If the 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 does. 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 turn on the power, the system may have failed a
power-on test. Recheck your jumper settings and connections or
call your retailer for assistance.
