Preface
This preface provides an overview of this guide, describes guide conventions, and lists other
publications that may be useful.
Introduction
This guide provides the required information to install the Summit24e3 switch and configure the
ExtremeWare™software running on the Summit24e3 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
•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.

Summit24e3 Switch Front View
Figure 1 shows the Summit24e3 switch front view.
Figure 1: Summit24e3 switch front view
The Summit24e3 switch has 24 autosensing 10BASE-T/100BASE-TX ports using RJ-45 connectors and
provides two unpopulated Extreme mini-GBIC ports using LC connectors. You can use the
1000BASE-SX mini-GBIC in the Summit24e3 switch.
Console Port
Use the console port (9-pin, “D”type connector) for connecting a terminal and carrying out local
management.
Reset Button
The reset button is used to hard reset the switch. Use a non-conductive tool to push the reset button.
