About This Manual
The NETGEAR® GS748T Software User Manual describes how to install, configure, operate, and
troubleshoot the GS748T Smart Switch using its included software. This boo k 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 GS748T 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 give
your network more advantage of its features. The web interface simplifies this configuration at all
levels.
How to Use This Book
This document describes configuration commands for the GS748T switch software. The
commands can all be accessed from the Web interface.
• Chapter 1, “Switch Management Overview” describes what you can expect from Web
management and gives host system requirements.
• Chapter 2, “Getting Started—Smart Wizard Discovery” describes how to use the Smart
Wizard Discovery utility to set up your switch so that you can communicate with it.
• Chapter 4, “Configuring the Switch” describes the features that your switch offers and tells
you how to configure and activate them in your network.
• Appendix A, “Specifications and Default Values” gives GS748T switch specifications and
lists default feature values.
• Appendix B, “Virtual Local Area Networks (VLANs)” describes some concepts of VLANs

Chapter 1
Switch Management Overview
Switch Management Interface
This section gives an overview of switch management, including the methods yo u can use to
manage your NETGEAR GS748T Smart Switch.
Your NETGEAR GS748T Smart Switch contains an embedded web server and management
software for managing and monitoring switch functions. This switch will function as a simple
switch without using the management software but its use enables you to configure more advanced
features and consequently improve switch efficiency and the overall performance of your network.
Web-Based Management enables you to monitor, configure, and control your switch remotely
using a common web browser, instead of having to use expensive and complicated SNMP
software products. Simply by using your web br owser, you can monitor the performance of your
switch, and optimize its configuration for your network. Using your browser , for example, you can
set up VLANs, traffic priority, and configure port trunking.
In addition, NETGEAR provides the Smart Wizard Discovery Utility program with this product.
This program runs under Microsoft Windows XP or Windows 2000 and provides a “front end”
which discovers the switches on your network segment. When you power up your switch for the
first time, Smart Wizard Discovery enables you to configure its basic network parameters without
prior knowledge of IP address or subnet mask. Following such configuration, this program leads
you into the Web Management interface.
Table 1-1 shows some features of Smart Wizard Discovery and Web Management.

v2.0, April 2007
Chapter 2
Getting Started—Smart Wizard Discovery
This section leads you through the steps necessary to begin managing your GS748T Smart Switch.
It covers how to install in a network that contains a DHCP server and one without DHCP.
Network with DHCP server
To install the switch in a network with a DHCP server, proceed as follows:
1. Connect the GS748T switch to a DHCP network.
2. Power on the switch by connecting its power cord.
3. Install the Smart Wizard Discovery Utility program on your computer.
4. Start the Smart Wizard Discovery utility.
5. Click Discover for the Smart Wizard Discovery to find your GS748T Smart Switch. You
should see a screen similar to that shown below.
Figure 2-1
2-1
v2.0, April 2007
GS748T Software User Manual
6. Make a note of the displayed IP address assigned by the DHCP server. You will need this
value to access the switch directly from a web browser (without using Smart Wizard
Discovery).
7. Select your switch by clicking on the line that shows it. Then click on the Web Access button.
The discovery utility displays a login window similar to the following:
Figure 2-2
Use your web browser to manage your switch. The default password is ‘password’.
Network without DHCP Server
This section describes how to set up your switch in a network without a DHCP server, and is
divided into the following tasks:
• Manually assign network parameters for your switch
• Configure the NIC settings on the host PC
• Log in to the web-based switch management utility
2-2 Getting Started—Smart Wizard Discovery
v2.0, April 2007
GS748T Software User Manual
Manually Assigning Network Parameters
If your network has no DHCP service, you must assign a static IP address to your switch. If yo u
choose, you can assign it a static IP address even if your network has DHCP service. Proceed as
follows:
1. Connect the GS748T Smart Switch to your existing network.
2. Power on the switch by plugging in the power cord (Default IP is 192.168.0.239).
3. Install the Smart Wizard Discovery Utility program on your computer
4. Start the Smart Wizard Discovery utility.
5. Click Discover for the Smart Wizard Discovery Utility to find your GS748T Smart Switch.
You should see a screen similar to that shown in Figure 2-1 on page 2-1.
6. Click on Configuration Setting. A screen similar to that shown below appears.
Figure 2-3
7. Choose Disable for DHCP.
8. Enter your chosen switch IP address, gateway IP address and subnet mask, and then type your
password and click “Set”. Please ensure that your PC and the GS748T Smart Switch are in the
same subnet. Make a note of these settings for later use.

NIC Setting on the Host that Accesses the GS748T Smart Switch
The settings of your network interface card (NIC) under MS Windows OS are made with entries
into the Windows screen pages shown below. For comparison, the settings pages of the switch are
also shown although they do not appear in the Windows view.
Figure 2-4
You need Windows Administrator privilege to change these settings.
1. On your PC, access the MS Windows operating system TCP/IP Properties page as shown. In
MS Windows XP this is found in Control Panel > Network Connections > Local Area
Connection > General: Properties.
2. Select Internet Protocol (TCP/IP) and click on Properties.
3. Set IP address and subnet mask appropriately. The subnet mask value should be identical to
that set in the switch. The PC IP address must be different from that of the switch but lie in the
same subnet.
4. Click on the Web Access button to enable the management screens as described in the
following section

procedure and the required equipment are described as follows. This procedure assumes that you
have downloaded or otherwise obtained the firmware upgrade and that you have it available as a
binary file on your computer. This procedure uses the TFTP protocol to implement the transfer
from computer to switch.
1. Enter the following values into the appropriate places in the form
• Firmware Path: The location of the new firmware file. You can click Browse to locate
the file.
• Password: Enter your password; the default password is “password”.
