About This Manual
The NETGEAR®GS108T Smart Switch Software Administration Manual describes how to install,
configure, operate, and troubleshoot the GS108T Gigabit Smart Switch using, its included
software. This book describes the software configuration procedures and explains the options
available within those procedures.
Who Should Use this Book
The information in this manual is intended for readers with intermediate to advanced system
management skills.
This document was created primarily for the system administrator who wishes to install and
configure the GS108T Smart Switch in a network. It assumes that the reader has a general
understanding of switch platforms and a basic knowledge of Ethernet and networking concepts. To
install this switch, it is not necessary to understand and use all of its capabilities. Once basic
configuration is performed, it will function in a network using its remaining factory default
parameters. However, a greater level of configuration—anywhere from the basic up to the
maximum possible—will allow your network the full benefit of the switch’s features. The web
interface simplifies this configuration at all levels.
How to Use This Book
This document describes configuration commands for the GS108T Smart Switch software. The
commands can all be accessed from the Web interface.
•Chapter 1, “Getting Started with Switch Management” describes how to use the SmartWizard
Discovery utility to set up your switch so that you can communicate with it.
•Chapter 2, “Introduction to the Web Browser Interface” introduces the Web browser interface.
•Chapter 3, “Managing System Settings” describes how to configure the System functions.
•Chapter 4, “Configuring the Switch” describes how to configure the Switch functions.
•Chapter 5, “Managing Firmware and Reset Options” describes the firmware upgrade
procedure and reset functions.
