Introduction to Troubleshooting

To troubleshoot HP VISUALIZE J6000 workstations, you must be familiar with the

HP-UX operating system and be able to start and stop processes. You should also be

familiar with the boot ROM diagnostics, ISL diagnostics, and the Support Tools Manager

online tests, which are described in this chapter.

First note any error or status messages, and then run the power-up boot ROM diagnostics,

known as Selftest. If the Selftest diagnostics fail, replace the FRU that is indicated. If the

tests pass but you still suspect a problem, run the ISL diagnostics and the Support Tools

Manager online tests.

For a complete description of using ISL diagnostics and using the Support Tools Manager,

see the Support Media User’s Manual (Part Number B3782-90176).

failing Field Replaceable Unit (FRU). Figure 3-1 on the next page contains the main

troubleshooting ﬂowchart. Figures 3-2 through 3-4 on the following pages contain the
