About This Manual
The NETGEAR®GS108T and GS110TP Software Administration Manual describes how to
configure and operate the GS108T Smart Switch and GS110TP Gigabit Smart Switch by using the
Web-based graphical user interface (GUI). This manual describes the software configuration
procedures and explains the options available within those procedures.
Audience
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 and GS110TP Gigabit 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 settings. 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.
Organization
The GS108T and GS110TP Smart Switch Software Administration Manual contains the following
chapters:
•Chapter 1, “Getting Started”on page 1-1 contains information about performing the initial
system configuration and accessing the user interface.
•Chapter 2, “Configuring System Information” on page 2-1 describes how to configure
administrative features such as SNMP, DHCP, and port information.

Chapter 1
Getting Started
This chapter provides an overview of starting your NETGEAR GS108T or GS110TP Smart
Switch and accessing the user interface. It also leads you through the steps to use the Smart
Control Center utility. This chapter contains the following sections:
•“Switch Management Interface” on page 1-1
•“Connecting the Switch to the Network” on page 1-2
•“Switch Discovery in a Network with a DHCP Server” on page 1-3
•“Switch Discovery in a Network without a DHCP Server” on page 1-5
•“Configuring the Network Settings on the Administrative System” on page 1-7
•“Web Access” on page 1-8
•“Smart Control Center Utilities” on page 1-9
•“Understanding the User Interfaces” on page 1-15
•“Interface Naming Convention” on page 1-21
Switch Management Interface
The NETGEAR GS108T and GS110TP Smart Switches contain an embedded Web server and
management software for managing and monitoring switch functions. The GS108T and GS110TP
function as simple switches without the management software. However, you can use the
management software to configure more advanced features that can improve switch efficiency and
overall network performance.
Web-based management lets you monitor, configure, and control your switch remotely using a
standard Web browser instead of using expensive and complicated SNMP software products. From
your Web browser, you can monitor the performance of your switch and optimize its configuration
for your network. You can configure all switch features, such as VLANs, QoS, and ACLs by using
the Web-based management interface.

GS108T and GS110TP Smart Switch Software Administration Manual
1-2 Getting Started
v1.0, April 2010
NETGEAR provides the Smart Control Center utility with this product. This program runs under
Microsoft®Windows®XP, Windows 2000, or Windows Vista®and provides a front end that
discovers the switches on your network segment (L2 broadcast domain). When you power up your
switch for the first time, use the Smart Control Center to discover the switch and view the network
information that has been automatically assigned to the switch by a DHCP server; or, if no DHCP
server is present on the network, use the Smart Control Center to discover the switch and assign
static network information.
In addition to enabling NETGEAR switch discovery, the Smart Control Center provides several
utilities to help you maintain the NETGEAR switches on your network, such as password
management, firmware upgrade, and configuration file backup. For more information, see “Smart
Control Center Utilities” on page 1-9.
Connecting the Switch to the Network
To enable remote management of the switch through a Web browser or SNMP, you must connect
the switch to the network and configure it with network information (an IP address, subnet mask,
and default gateway). The switch has a default IP address of 192.168.0.239 and a default subnet
mask of 255.255.255.0.
Use one of the following three methods to change the default network information on the switch:
• Dynamic assignment through DHCP—DHCP is enabled by default on the switch. If you
connect the switch to a network with a DHCP server, the switch obtains its network
information automatically. You can use the Smart Control Center to discover the
automatically-assigned network information. For more information, see “Switch Discovery in
a Network with a DHCP Server” on page 1-3
• Static assignment through the Smart Control Center—If you connect the switch to a network
that does not have a DHCP server, you can use the Smart Control Center to assign a static IP
address, subnet mask, and default gateway. For more information, see “Switch Discovery in a
Network without a DHCP Server” on page 1-5
• Static assignment by connecting from a local host—If you do not want to use the Smart
Control Center to assign a static address, you can connect to the switch from a host
(administrative system) in the 192.168.0.0/24 network and change the settings by using the
Web-based management interface on the switch. For information about how to set the IP
address on the administrative system so it is in the same subnet as the default IP address of the
switch, see “Configuring the Network Settings on the Administrative System” on page 1-7.

v1.0, April 2010
Switch Discovery in a Network with a DHCP Server
This section describes how to set up your switch in a network that has a DHCP server. The DHCP
client on the switch is enabled by default. When you connect it to your network, the DHCP server
will automatically assign an IP address to your switch. Use the Smart Control Center to discover
the IP address automatically assigned to the switch.
To install the switch in a network with a DHCP server, use the following steps:
1. Connect the switch to a network with a DHCP server.
2. Power on the switch by connecting its AC-DC power adapter. For the GS108T, you can also
power on the switch by connecting Port 1 to a PoE Power Sourcing Equipment (PSE).
3. Install the Smart Control Center on your computer.
4. Start the Smart Control Center.
5. Click Discover for the Smart Control Center to find your switch. You should see a screen
similar to the one shown in Figure 1-1.
Figure 1-1

v1.0, April 2010
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 the Smart Control
Center).
7. Select your switch by clicking the line that displays the switch, then click the
Web Browser Access button. The Smart Control Center displays a login window similar to
Figure 1-3.
Use your Web browser to manage your switch. The default password is password. Then use
this page to proceed to management of the switch covered in “Using the Web Interface” on
page 1-15.

Switch Discovery in a Network without a DHCP Server
This section describes how to use the Smart Control Center to set up your switch in a network
without a DHCP server. If your network has no DHCP service, you must assign a static IP address
to your switch. If you choose, you can assign it a static IP address, even if your network has DHCP
service.
To assign a static IP address:
1. Connect the switch to your existing network.
2. Power on the switch by plugging in the AC-DC power adapter. For the GS108T, you can also
power on the switch by connecting Port 1 to a PoE PSE.
3. Install the Smart Control Center on your computer.
4. Start the Smart Control Center.
5. Click Discover for the Smart Control Center to find your GS108T or GS110TP switch. The
utility broadcasts Layer 2 discovery packets within the broadcast domain to discover the
switch.You should see a screen similar to Figure 1-1 on page 1-3.

v1.0, April 2010
6. Select the switch, then click Configure Device. The page expands to display additional fields
at the bottom of the page, as Figure 1-4 shows.
7. Choose the Disabled radio box to disable DHCP.
8. Enter the static switch IP address, gateway IP address and subnet mask, and then type your
password and click Apply.
Please ensure that your PC and the switch are in the same subnet. Make a note of these settings for
later use.
Figure 1-4
Note: You must enter the current password every time you use the Smart Control
Center to update the switch setting. The default password is password.
