GS108T and GS110TP Smart Switch Software Administration Manual
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.
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 18.

Chapter 1: Getting Started |11
GS108T and GS110TP Smart Switch Software Administration Manual
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 12
• 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 14
• 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 15.

12 |Chapter 1: Getting Started
GS108T and GS110TP Smart Switch Software Administration Manual
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.

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
the following figure.
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

GS108T and GS110TP Smart Switch Software Administration Manual
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 on page 12.
6. Select the switch, then click Configure Device. The page expands to display additional
fields at the bottom of the page, as the following figure 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.

Chapter 1: Getting Started |15
GS108T and GS110TP Smart Switch Software Administration Manual
Tip: You must enter the current password every time you use the Smart
Control Center to update the switch setting. The default password is
password.
Please ensure that your PC and the switch are in the same subnet. Make a note of these
settings for later use.
Configuring the Network Settings on the Administrative
System
If you choose not to use the Smart Control Center to configure the network information on the
switch, you can connect directly to the switch from an administrative system, such as a PC or
laptop computer. The IP address of the administrative system must be in the same subnet as
the default IP address on the switch. For most networks, this means you must change the IP
address of the administrative system to be on the same subnet as the default IP address of
the switch (192.168.0.239).
To change the IP address on an administrative system running a Microsoft®Windows®
operating system, open the Internet Protocol (TCP/IP) properties screen that you access
from the Local Area Connection properties, as shown in the following figure. You need
Windows Administrator privileges to change these settings.

GS108T and GS110TP Smart Switch Software Administration Manual
WARNING!
When you change the IP address of your administrative system,
you will loose your connection to the rest of the network. Be sure
to write down your current network address settings before you
change them.
To modify the network settings on your administrative system:
1. On your PC, access the MS Windows operating system TCP/IP Properties.
2. Set the IP address of the administrative system to an address in the 192.168.0.0 network,
such as 192.168.0.200. The IP address must be different from that of the switch but within
the same subnet.
3. Click OK.
To configure a static address on the switch:
1. Use a straight-through cable to connect the Ethernet port on the administrative system
directly to any port on the GS108T or GS110TP.
2. Open a Web browser on your PC and connect to the management interface as described in
Web Access on page 17.
3. Change the network settings on the switch to match those of your network (this procedure is
described in IP Configuration on page 34).
After you change the network settings on the switch, return the network configuration on your
administrative system to the original settings.
