To Use These Procedures for Troubleshooting
1. Identify the problem as much as possible by symptom or error code. For more
information about error codes, see Appendix B, “Sense Data Values.”
2. Use the Contents page for this chapter to locate the section in this chapter that
relates to the problem you identified.
3. Begin the troubleshooting analysis with the “Fault Isolation Entry MAP” on
page 48. This flow chart can help eliminate basic problems and direct you to other
flow charts.
4. Follow the flow charts step-by-step, testing the library after each corrective action.
While troubleshooting, you can also refer to the Sun ETL 7/3500 Diagnostic Software
User’s Manual and Sun ETL 7/3500 Operator’s Guide.
5. Stop the troubleshooting procedure when the symptom or error disappears.
