ExtremeWare 7.2e Installation and User Guide 15
Preface
This preface provides an overview of this guide, describes guide conventions, and lists other
publications that might be useful.
Introduction
This guide provides the required information to install the Summit 400-48 switch and configure the
ExtremeWare™software running on the Summit 400-48 switch.
This guide is intended for use by network administrators who are responsible for installing and setting
up network equipment. It assumes a basic working knowledge of:
•Local area networks (LANs)
•Ethernet concepts
•Ethernet switching and bridging concepts
•Routing concepts
•Internet Protocol (IP) concepts
•Routing Information Protocol (RIP) and Open Shortest Path First (OSPF).
•IP Multicast concepts
•Protocol Independent Multicast (PIM) concepts
•Simple Network Management Protocol (SNMP)
NOTE
If the information in the release notes shipped with your switch differs from the information in this guide,
follow the release notes.
Conventions
Table 1 and Table 2 list conventions that are used throughout this guide.

simply says “type.”
[Key] names Key names are written with brackets, such as [Return] or [Esc].
If you must press two or more keys simultaneously, the key names are linked with a
plus sign (+). Example:
Press [Ctrl]+[Alt]+[Del].

Documentation for Extreme Networks products is available on the World Wide Web at the following
location:
http://www.extremenetworks.com/
Using ExtremeWare Publications Online
You can access ExtremeWare publications by downloading them from the Extreme Networks World
Wide Web location or from your ExtremeWare product CD. Publications are provided in Adobe®
Portable Document Format (PDF). Displaying or printing PDF files requires that your computer be
equipped with Adobe®Reader® software, which is available free of charge from Adobe Systems
Incorporated.
The following two ExtremeWare publications are available as PDF files that are designed to be used
online together:
•ExtremeWare 7.2e Installation and User Guide
•ExtremeWare 7.2e Command Reference Guide
The user guide PDF file provides links that connect you directly to relevant command information in
the command reference guide PDF file. This quick-referencing capability enables you to easily find
detailed information in the command reference guide for any command mentioned in the user guide.
To ensure that the quick-referencing feature functions properly, follow these steps:
1Download both the user guide PDF file and the command reference guide PDF file to the same
destination directory on your computer.
2You may open one or both PDF files and to enable cross-referenced linking between the user guide
and command reference guide; however, it is recommended that for ease of use, you keep both files
open concurrently on your computer desktop.
NOTE
If you activate a cross-referencing link from the ExtremeWare 7.2e Installation and User Guide PDF file
to the command reference PDF file when the command reference PDF file is closed (that is, not
currently open on your computer desktop), the system will close the user guide PDF file and open the
command reference PDF file. To keep both PDF files open when you activate a cross-reference link,
open both PDF files before using the link.
