Getting Started with the Smart Switches
This chapter provides an overview of starting your GS728TS, GS728TPS, GS752TS, or
GS752TPS 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 10
• Connecting the Switch to the Network on page 11
• Switch Discovery in a Network with a DHCP Server on page 12
• Switch Discovery in a Network without a DHCP Server on page 14
• Configuring the Network Settings on the Administrative System on page 15

Switch Management Interface
The NETGEAR GS728TS, GS728TPS, GS752TS, and GS752TPS Gigabit Smart Switches
contain an embedded Web server and management software for managing and monitoring
switch functions. Each switch can function as a simple switch 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
10
GS728TS, GS728TPS, GS752TS, and GS752TPS Gigabit Smart Switches
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 17.
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
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
System on page 15.

GS728TS, GS728TPS, GS752TS, and GS752TPS Gigabit Smart Switches
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.
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, Smart Switch Discovery.
Figure 1. Smart Switch Discovery

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

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.
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 GS728TS, GS728TPS, GS752TS,
or GS752TPS 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.
14
GS728TS, GS728TPS, GS752TS, and GS752TPS Gigabit Smart Switches
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.
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
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.
Windows®

GS728TS, GS728TPS, GS752TS, and GS752TPS Gigabit Smart Switches
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 GS728TS, GS728TPS, GS752TS, or GS752TPS.
2. Open a Web browser on your PC and connect to the management interface as described in
Web Access on page 16.
3. Change the network settings on the switch to match those of your network (this procedure is
described in
After you change the network settings on the switch, return the network configuration on your
administrative system to the original settings.
IP Configuration on page 35).

Understanding the User Interfaces
The GS728TS, GS728TPS, GS752TS, and GS752TPS switches software includes a set of
comprehensive management functions for configuring and monitoring the system by using
one of the following methods:
• Web user interface
• Simple Network Management Protocol (SNMP)
Each of the standards-based management methods allows you to configure and monitor the
components of the GS728TS, GS728TPS, GS752TS, and GS752TPS switches software.
The method you use to manage the system depends on your network size and requirements,
and on your preference.

Device View
The Device View is a Java® applet that displays the ports on the switch. This graphic provides
an alternate way to navigate to configuration and monitoring options. The graphic also
provides information about device ports, current configuration and status, table information,
and feature components.
The Device View is available from the System> Device View page.
Depending upon the status of the port, the LED of the port status illuminates in Device View
either red, green, or gray. Green indicates that the port is enabled. Red indicates that an error
has occurred on the port, or red indicates that the link is disabled. Gray is applicable for ports
27 and 28 on the GS728TS/GS728TPS and ports 51 and 52 on the GS752TS/GS752TPS
and indicates that the port is working in stack mode. The LED of the port speed illuminates
either green or yellow.
• A green LED indicates operational ports at 1 Gbps or 2.5 Gbps (if used for stacking) link
speed.
• A yellow LED indicates operational ports at 10/100 Mbps link speed.
The System LEDs are located on the left side of the front panel.
Power/Status LED
The power LED is a bicolor LED that serves as an indicator of power and diagnostic status.
The following indications are given by the following LED states:
• A solid Green LED indicates that the power is supplied to the switch and operating
normally.
• A solid Yellow LED indicates that system is in the boot-up stage.
• No lit LED indicates that power is disconnected.
FAN Status LED
FAN status is indicated as follows:
• A solid yellow LED indicates that the fan is faulty.
• No lit LED indicates that the fan is operating normally.
Stack Master LED
The Stack Master LED is lit if there is an active stack link and the unit is in stack mode.
• A solid Green LED indicates that the switch acts as a master unit in a stack of switches.
• No lit LED indicates that the switch acts as a slave member in a stack of switches.
Seven-Segment LED for the Stacking ID
A solid Green LED displays the stack ID (1–6).

Using SNMP
The GS728TS, GS728TPS, GS752TS, and GS752TPS switches software supports the
configuration of SNMP groups and users that can manage traps that the SNMP agent
generates. GS728TS, GS728TPS, GS752TS, and GS752TPS switches use both standard
public MIBs for standard functionality and private MIBs that support additional switch
functionality. All private MIBs begin with a “-” prefix. The main object for interface
configuration is in -SWITCHING-MIB, which is a private MIB. Some interface configurations
also involve objects in the public MIB, IF-MIB.
SNMP is enabled by default. The System > Management > System Information Web page,
which is the page that displays after a successful login, displays the information you need to
configure an SNMP manager to access the switch.
Any user can connect to the switch using the SNMPv3 protocol, but for authentication and
encryption, the switch supports only one user which is admin; therefore there is only one
profile that can be created or modified.
To configure authentication and encryption settings for the SNMPv3 admin profile by using
the Web interface:
1. Navigate to the System > SNMP > SNMPv3 > User Configuration page.
2. To enable authentication, select an Authentication Protocol option, which is either MD5 or
SHA.
3. To enable encryption, select the DES option in the Encryption Protocol field. Then, enter
an encryption code of eight or more alphanumeric characters in the Encryption Key field.
4. Click Apply.
To access configuration information for SNMPv1 or SNMPv2, click System > SNMP >
SNMPv1/v2 and click the page that contains the information to configure.

Interface Naming Convention
The GS728TS, GS728TPS, GS752TS, and GS752TPS switches software supports physical
and logical interfaces. Interfaces are identified by their type and the interface number. The
physical ports are gigabit interfaces and are numbered on the front panel. You can configure
the logical interfaces by using the software. The following table describes the naming
convention for all interfaces available on the switch.
Table 2. Interface Naming Conventions
Interface Description Example
Physical The physical ports are gigabit Ethernet
interfaces and are numbered sequentially
starting from one. The number before the slash
indicates the unit number of the stack member.
Link Aggregation Group (LAG) LAG interfaces are logical interfaces that are
only used for bridging functions.
CPU Management Interface This is the internal switch interface responsible
for the switch base MAC address. This interface
is not configurable and is always listed in the
MAC Address Table.
