Troubleshooting Chapter Overview Chapter Overview This chapter contains the following main sections: • Introduction to Troubleshooting • Flowcharts for Troubleshooting • Dealing with a Boot Failure • Identifying LCD-Indicated Conditions • Running System Verification Tests • Running ODE-Based Diagnostics • Fan Problems Introduction to Troubleshooting To troubleshoot HP VISUALIZE J5000 and J7000 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).
