Preface

Welcome to the Model 2216T Ethernet Switch. This switch features sixteen

10BASE-T ports and a 100BASE-X uplink port. Network performance can be

dramatically improved when a workgroup switch is used to segment 10BASE-T

hubs and provide a high-capacity 100 megabit per second (Mb/s) connection to a

server or network center.

Purpose

This guide provides information about the features and capabilities of the

Model 2216T switch and includes instructions for installing the switch and setting

it up for network management.

Audience

This guide is intended for Ethernet local area network administrators with the

following background:

• Working knowledge of Ethernet local area networks (LANs)

• Bay Networks

®

network experience (helpful but not required)

• Familiarity with Transmission Control Protocol/Internet Protocol (TCP/IP)

and Simple Network Management Protocol (SNMP)

Conventions

This section describes the conventions used in this guide.
