This chapter provides information about isolating a failing Field Replaceable Unit
(FRU).
To troubleshoot HP Apollo workstations, you must be familiar with the HP–UX
operating system. You must be able to start and stop processes. You should also be
familiar with the Boot ROM Test Mode, ISL diagnostics, and the SupportWave
online tests.
For Series 700 systems, you note any error or status messages, and then run the
power–up boot ROM diagnostics, known as Self Test. If tfie Self Test diagnostics
fail, replace the FRU that is indicated. If the tests pass but you still suspect a prob-
lem, run the ISL dia~ostics and the SupportWave online tests. Refer to the fol-
lowing sections for &ore information about Self Test.
For a complete description on using ISL diagnostics and SupportWave. see the
Precision Architecture RISC HPApollo 9000 Seties 700 Diagnostics Manual.
