Preface
Intended Audience
This manual is written for Digital customer service engineers and self-
maintenance customers.
Document Structure
This manual uses a structured documentation design. Topics are organ-
ized into small sections for efficient on-line and printed reference. Each
topic begins with an abstract. You can quickly gain a comprehensive over-
view by reading only the abstracts. Next is an illustration or example,
which also provides quick reference. Last in the structure are descriptive
text and syntax definitions.
This manual has three chapters and two appendixes, as follows:
•Chapter 1, Troubleshooting During Power-Up, explains what
can go wrong during power-up and how to identify the cause of the
problem.
•Chapter 2, System Self-Test, tells how to interpret the self-test
console display and module LEDs.
•Chapter 3, Diagnostics, describes the various diagnostics used to
test the system.
•Appendix A contains the parse trees, and Appendix B contains
guidelines for troubleshooting the power system.

Conventions Used in This Document
The text shown in command syntax uses these conventions:
•Bold text indicates elements to be typed at the terminal.
•Brackets ([]) indicate that an element is optional.
•Braces ({}) indicate a choice from the enclosed list.
•Angle brackets (<>) indicate that the enclosed text is not a literal de-
piction of the element but instead a reference to the kind of item that
can appear in that position.
Icons such as those shown below are used in illustrations for designating
part placement in the system described. A shaded area in the icon shows
the location of the component or part being discussed.
