you can load it from tape or CD. For information on how to use the Sundiag
System Exerciser, see the Sundiag User's Guide. Appendix A, "Loopback
Connectors" in the Sundiag User's Guide explains how to connect the external
loopback connectors required for some options. If Sundiag passes, the system
is operating properly. If Sundiag fails, the system is not operating properly. To
identify the problem when Sundiag fails, first run the POST. If all POST tests
pass, next run the SunDiagnostic Executive to isolate the problem.
The SunDiagnostic Executive is an independent operating system. It runs
exhaustive subsystem tests independent of SunOS. Run the SunDiagnostic
Executive if all POST tests pass in order to troubleshoot what field-replaceable
unit needs to be replaced. For information on POST, see "Power-On Self-Test
Detailed Description" earlier in this chapter. The SunDiagnostic Executive,
which provides you with thorough diagnostics, is described in the
SunDiagnostic Executive User's Guide for the SPARCstations.
