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:

OTE

Emphasizes important information or calls your attention to related

features or instructions.

AUTION

Alerts you to a potential hazard that could cause loss of data, or

damage the system or equipment.

ARNING

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:

The Installation Guide

Also, as part of the switch’s software, there is an online web-based help

that describes all management related features.

REVISION HISTORY This section summarizes the changes in each revision of this guide.
