Document Organization

The major sections of this publication follow:

• Chapter 1, "LightStream 100 ATM Switch Overview," provides an overview of the LightStream 100 switch features and physical specifications.

• Chapter 2, "Preparing for Installation," provides safety information and describes the tasks you must perform before you install the LightStream 100 switch.

• Chapter 3, "Installing the LightStream 100 ATM Switch," includes tools and equipment, complete installation instructions, and initial software configuration instructions.

• Chapter 4, "Maintaining and Upgrading the LightStream 100 ATM Switch," explains how to add and replace equipment, upgrade the software, and move equipment.

• Chapter 5, "Configuring the Software," provides instructions for software configuration following the initial installation.

• Chapter 6, "Troubleshooting," provides procedures for identifying system errors.

• Appendix A, "Command Reference," contains the complete command set for the LightStream 100 switch, including detailed command syntax and examples.

• Appendix B, "Translated Safety Warnings," contains warning messages in multiple languages.

Document Conventions

This section explains the conventions used in this manual to convey instructions and information.

Command descriptions use the following conventions:

• Commands and keywords are in boldface font.

• Variables for which you supply values are in italic font.

• Elements in square brackets ([ ]) are optional.

• Alternative but required keywords are grouped in braces ({ }) and are separated by a vertical bar ( | ).

Samples use the following conventions:

• Terminal sessions are printed in screen font.

• Information you enter is in boldface screen font.

• Nonprinting characters are shown in angle brackets (< >).

• Information the system displays is in screen font, with default responses in square brackets

Notes, timsavers, cautions, and warnings use the following conventions and symbols:

---

Note Means reader take note. Notes contain helpful suggestions or references to materials not contained in this manual.

---

Time Saver Means the described actions save time. You can save time by performing the action described in the paragraph.

Caution  This caution symbol means reader be careful. You are capable of doing something that might result in equipment damage or loss of data.

Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. The warning symbol also means that you can see the warning in multiple languages in "Translated Safety Warnings."
