INTRODUCTION

1.1 ABOUT THIS MANUAL

This manual is for system administrators responsible for conﬁguring, monitoring, and maintaining the SmartSTACK 10 ELS10-26TX. You should have a familiarity with networking concepts and principles. In addition, a basic understanding of SNMP is helpful.

Some SmartSTACK 10 ELS10-26 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 10 ELS10-26’s switching functions, applications, and the Local Console Manager (LCM).

•Chapter 2, Unpacking and Installing Your ELS10-26, describes the SmartSTACK 10 ELS10-26 front and rear panels, how to install the SmartSTACK 10 ELS10-26, how to connect the Local Console Manager (LCM), and how to connect the ELS10-26 to the network.

•Chapter 3, Configuring Your ELS10-26, provides instructions for conﬁguring the SmartSTACK 10 ELS10-26 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 ELS10-26, describes how to monitor SmartSTACK 10 ELS10-26 status and statistics. It also describes how to manage the SmartSTACK 10 ELS10-26 Ethernet ports using the Local Console Manager (LCM).
