Conventions
This book and the other books in this series follow conventions for structuring information as
described next.
Headings
Every chapter starts with a brief description of the information that you can find in that chapter, which
correlates with the major headings in that chapter. Each major heading corresponds to a task or
concept that is important for you to understand. Headings are of a different size and type to make them
easy to skim, whether you are viewing an online or print copy of this document.
Typeface
This book uses the following typeface conventions:
Bold Used for the names of screen elements like buttons, drop-down lists, or fields. For
example, when you are finished with a dialog box, you click the OK button.
Code
Used for text that the user must type to use the product.
Italic Used for book titles, variables, and important terms.
Hyperlink
Used for web site and cross-reference links.
Cross-References
When a topic is covered in depth elsewhere in this guide or in another book in this series, a cross-
reference to the other information will be provided. Cross-references within this book take this form:
“For more information about conventions, see page 6, Conventions.” Cross-references to other
publications take this form: “For more information about <topic>, see Publication Name.”
Messages
Messages are special text that are emphasized by font, format, and icons. 3Com documents have four
types of messages:
•Warning
•Caution
•Note
•Tip
A description of each message type with an example message follows.
Warning
Warnings tell you how to avoid physical injury to people or equipment. For people, injury includes
anything from temporary conditions, such as pain, to irreversible conditions such as death. For
equipment, injury means anything requiring repair. Warnings tell you what you should or should not
do, and the consequences of not heeding the warning.
