About This Guide

Purpose

This guide gives specific information on how to operate and use the management functions of the switch.

Audience

The guide is intended for use by network administrators who are responsible for operating and maintaining network equipment; consequently, it assumes a basic working knowledge of general switch functions, the Internet Protocol (IP), and Simple Network Management Protocol (SNMP).

Conventions

The following conventions are used throughout this guide to show information:

Note: Emphasizes important information or calls your attention to related features or

instructions.

Caution: Alerts you to a potential hazard that could cause loss of data, or damage the

system or equipment.

Warning: Alerts you to a potential hazard that could cause personal injury.

Related Publications

The following publication details the hardware features of the switch, including the physical and performance-related characteristics, and how to install the switch:
