Diagnostic Testing Preparation
Caution: Turn off devices before disconnecting cables. Before disconnecting
any peripheral cables from the system, turn off the system and any external
peripheral devices. Failure to do so can cause permanent damage to the
system and/or the peripheral devices.
1. Turn off the system and all external peripheral devices. Disconnect all of them from the
system, except the keyboard and video monitor.
2. Make sure the system power cord is plugged into a properly grounded AC outlet.
3. Make sure your video display monitor and keyboard are correctly connected to the
system. Turn on the video monitor. Set its brightness and contrast controls to at least two
thirds of their maximum ranges. See the documentation supplied with your video display
monitor.
4. If the operating system normally loads from the hard disk drive, make sure there is no
diskette in drive A. Otherwise, place a diskette containing the operating system files in
drive A.
5. Turn on the system. If the power LED does not light, see Power Light Problems.
Initial System Startup Problems
Problems that occur at initial system startup are usually caused by incorrect installation or
configuration. Hardware failure is a less frequent cause.
Checklist
Are the power supplies turned on? Check the switches on the back of the chassis.
Are all cables correctly connected and secured?
Are the processors fully seated in their slots on the server board?
Are all add-in PCI boards fully seated in their slots on the server board?
Are all jumper settings on the server board correct?
Are all jumper and switch settings on add-in boards and peripheral devices correct? To

applicable, ensure that there are no conflicts; for example, two add-in boards sharing the
same interrupt.

Are all peripheral devices installed correctly?
If the system has a hard disk drive, is it properly formatted or configured?

Are the configuration settings made in BIOS Setup correct?
Is the operating system properly loaded? Refer to the operating system documentation.
Did you press the system power on/off switch on the front panel to turn the server on
(power on light should be lit)?
Is the system power cord properly connected to the system and plugged into a NEMA 5-
15R outlet for 100-120 V~ or a NEMA 6-15R outlet for 200-240 V~?
