CHAPTER 1: INTRODUCTION

Congratulations on your purchase of the NETGEAR GS748T Gigabit Smart Switch! Your NETGEAR Switch is a state-of-the-art, high-performance,
IEEE-compliant network solution designed for users who require a large number of ports and want the power of Gigabit connectivity to eliminate
bottlenecks, boost performance, and increase productivity. There are 48 twisted-paired ports with 4 SFP GBIC slots on the front panel of the switch
that support non-stop 10/100/1000 networks. To simplify installation, the switch is shipped ready for use out of the box.

This chapter serves as the introduction for using your NETGEAR GS748T Gigabit Smart Switch and provides the following information:

• Overview

• Switch Features

• Package contents

Overview

Your NETGEAR GS748T Gigabit Smart Switch provides 48 twisted-paired ports with 4 built-in Small Form Factor (SFP) GBIC slots that support
non-stop 10/100/1000 fiber networks. Using these Gigabit slots, you can create high-speed connections to a server or network backbone. For
example, you can:

• Connect switches to each other with high-speed links

• Link to high-speed servers

• Provide 10/100/1000 copper and fiber connectivity

Your NETGEAR GS748T Gigabit Smart Switch also provides the benefit of administrative management with a complete package of features for the
observation, configuration, and control of your network. With a Web-based Graphical User Interface (GUI), the switch’s many capabilities can be
viewed and used in a simple and intuitive manner. There is also an easy to use switch management utility that runs on a PC. The switch’s
management features include configuration for port and switch information, VLAN for traffic control, port trunking for increased bandwidth, and
Class of Service (CoS) for traffic prioritization. These features and more will allow you to better understand and control your network.

Your NETGEAR GS748T Gigabit Smart Switch can be free-standing, or rack mounted in a wiring closet or equipment room. It is IEEE-compliant
and offers low latency for high-speed networking. It includes 48 auto-sensing 10/100/1000 Ethernet ports with 4 SFP GBIC slots. All ports can
automatically negotiate to the highest speed. This capability makes the switch ideal for environments that have a mix of Ethernet, Fast Ethernet, or
Gigabit Ethernet devices. In addition, all 10/100/1000 Mbps ports operate in half- or full-duplex mode, increasing the maximum bandwidth of each
connection up to either 20 Mbps, 200 Mbps, or 2000 Mbps, respectively. The maximum segment length is 328 feet (100 meters) over Category 5
unshielded twisted-pair (UTP) cable.
