INTRODUCTION

1.1 ABOUT THIS MANUAL

This manual is for system administrators responsible for conﬁguring, monitoring, and maintaining the SmartSTACK 100 ELS100-16TX. You should have a familiarity with networking concepts and principles. In addition, a basic understanding of SNMP is helpful.

Some SmartSTACK 100 ELS100-16TX conﬁgurations can only be done using an SNMP-based Network Management System (NMS). Where applicable, this manual provides instructions for using the Local Console Manager (LCM) to perform basic conﬁguration. Where it is not possible to use LCM, general instructions and guidelines applicable to most NMSs are provided.

The contents of each chapter are described below.

•Chapter 1, Introduction, outlines the contents of this manual and provides an overview of the SmartSTACK 100 ELS100-16TX’s switching functions, applications, and the Local Console Manager (LCM).

•Chapter 2, Unpacking and Installing Your ELS100-16TX, describes the SmartSTACK 100 ELS100-16TX front and rear panels, how to install the SmartSTACK 100 ELS100-16TX, how to connect the Local Console Manager (LCM), and how to connect the ELS100-16TX to the network.

•Chapter 3, Configuring Your ELS100-16TX, provides instructions for conﬁguring the SmartSTACK 100 ELS100-16TX using the Local Console Manager (LCM). It also provides some common Management Information Base (MIB) variables you may want to change.

•Chapter 4, Monitoring and Managing Your ELS100-16TX, describes how to monitor SmartSTACK 100 ELS100-16TX status and statistics. It also describes how to manage the SmartSTACK 100 ELS100-16TX Ethernet ports using the Local Console Manager (LCM).
