Troubleshooting
Introduction
This chapter presents the overall strategy for troubleshooting failures on the HP 3000/9x9KS, HP 9000/
Kxx0 Class systems and HP VISUALIZE Kx50-EG, Kx60-EG, and Kx60-XP workstations, and provides
some procedures you can follow that will help you isolate most system problems.
The chapter is organized so that you can diagnose failures in a logical manner from the "top down",
regardless of your experience. You can use the information and procedures in this chapter to isolate and
correct nearly all system hardware failures.
If a problem occurs that is not covered here, you should consult more experienced support personnel
within your organization or contact the nearest Hewlett-Packard Response Center for assistance. Care
should be taken before taking any steps to remedy a failure. Always collect as much information as possi-
ble about the failure.
Never swap out a Field Replaceable Unit (FRU) until you have ascertained the following:
• The failure symptoms
• All status indicators
• All console and front panel messages
• System configuration
• Number of users logged on
• Application or tasks running at the time of the failure
• All other information that may help describe the failure
Use this information, along with the procedures in this chapter, to aid in selecting appropriate corrective
action. Keep a log of all actions you take for future reference.
