Introduction to Troubleshooting
To troubleshoot HP VISUALIZE J6700 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).
Flowcharts for Troubleshooting
The following four figures contain troubleshooting flowcharts you can follow to isolate a
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
flowcharts for console, bootable device, and HP-UX troubleshooting, respectively.
