GS728TXS/GS752TXS Smart Switch
Overview
The NETGEAR GS728TXS/GS752TXS Smart Switch provides either 24 (GS728TXS) or 48
(GS752TXS) twisted-pair ports that support nonstop 10/100/1000M networks. The switch
also has four built-in enhanced small form factor pluggable (SFP+) GBIC slots that support
1000M and 10G optical modules or up to two stacking modules.
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 10/100/1000M copper and 1000M/10G fiber connectivity
•Connect up to six switches in a stack to create a high-port-capacity solution with a single
point of administration
The smart switch also provides the benefit of administrative management with a complete
package of features for the observation, configuration, and control of the network. You can
use the simple and intuitive web-based graphical user interface (GUI) to view and use the
switch’s many capabilities. 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 prioritizing traffic. These features provide better understanding and
control of the network. Initial discovery of the switch on the network requires the Smart
Control Center program, a utility that runs on a Windows computer.
The smart switch can be freestanding, stacked with other switches, or rack-mounted in a
wiring closet or equipment room. It is IEEE-compliant and offers low latency for high-speed
networking. All ports can automatically negotiate to the highest speed which makes the
switch ideal for environments that have a mix of Ethernet, Fast Ethernet, Gigabit Ethernet, or
10-Gigabit Ethernet devices. All RJ-45 ports operate in half-duplex or full-duplex mode. The
maximum segment length is 328 feet (100 meters) over Category 5 unshielded twisted-pair
(UTP) cable.

Stacking
A stack can be controlled and managed from a single unit called the master unit. Any other
unit member of the stack is called a stack slave member.
In particular, firmware can be downloaded from the stack master to the other units in the
stack.
A unit serving as stack master runs the fully operational software of a switch. In addition, it
runs the master part of the distributed switching application that configures and manages all
other units in the stack. Generally, the master operates the remote slave’s low-level drivers,
through the distributed switching application part that is running in the context of the slave.
During stacking setup, the switches autoselect one device as the stacking master. All other
devices are named as slave stack members and assigned unique unit IDs. One of the slave
units is designated as the backup master. The backup master acts as a slave stack master,
but can become a stack master if the stack master fails. In the default configuration, the
master and backup master are assigned unit IDs of 1 and 2, respectively. The administrator
can use the web interface to configure different ID assignments. The stack master provides a
single point of control and management as well as a single interface in which to control and
manage the stack.

8
GS728TXS/GS752TXS Smart Switch
Switch software is downloaded separately for each stack member. However, all units in the
stack must be running the same software version.
A stack unit can operate in one of the following modes:
•A standalone unit runs as a general switch. The standalone unit does not run the stacking
application until it is connected to a stack.
•The master unit manages the entire stack, and is responsible for the entire stack
configuration. All protocols run in the context of the master unit. It updates and
synchronizes the backup master.
•A master-backup unit runs as a slave unit as described earlier, and in addition, it
continuously monitors the existence and operation of the stack master. If the master unit
fails, the master-backup unit assumes the stack-master role (switchover).
•A slave unit runs only a slave version of the distributed switching algorithm, which allows
the applications running on the master unit’s CPU to control and manage the resources of
the slave unit.
A stack can contain a mix of up to six GS728TXS and GS752TXS switches.

Device Hardware Interfaces
This section describes the hardware interfaces on the smart switch.
RJ-45 Ports
RJ-45 ports are AutoSensing ports. When you insert a cable into an RJ-45 port, the switch
automatically ascertains the maximum speed (10, 100, or 1000 Mbps) and duplex mode
(half-duplex or full-duplex) of the attached device. All ports support only an unshielded
twisted-pair (UTP) cable terminated with an 8-pin RJ-45 plug.
To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink. This
technology allows attaching devices to the RJ-45 ports with either straight-through or
crossover cables. When you insert a cable into the switch’s RJ-45 port, the switch
automatically:
•Senses whether the cable is a straight-through or crossover cable.
•Determines whether the link to the attached device requires a “normal” connection (such
as when you are connecting the port to a computer) or an uplink connection (such as
when you are connecting the port to a router, switch, or hub).
•Automatically configures the RJ-45 port to enable communications with the attached
device. The Auto Uplink technology compensates for setting uplink connections, while
eliminating concern about whether to use crossover or straight-through cables when you
attach devices.

14
GS728TXS/GS752TXS Smart Switch
SFP+ Ports
To enable you to have fiber connections on your network, four SFP+ ports (25 through 28)
accommodate standard 1000M and 10G SFP+ transceiver modules, which are sold
separately.
The SFP+ ports can alternatively be used to connect the switch to a stack. Up to two ports
(ports 27 and 28) can be used at a time as stacking ports.
Reset Button
The smart switch has a Reset button on the front panel to allow you to manually reboot the
switch. This action is equivalent to powering the unit off and back on. The last saved
configuration is loaded into the switch as it resets. To use the Reset button, insert a device
such as a straightened paper clip into the opening to press the recessed button. The front
panel LEDs should turn off and light again as the switch performs its power-on self-test
(POST).
Factory Defaults Button
The smart switch has a Factory Defaults button on the front panel so that you can remove the
current configuration and return the device to its factory settings. When you enable the
Factory Defaults button, all settings including the password, VLAN settings, and port
configurations are removed. To use the Factory Defaults button, insert a device such as a
straightened paper clip into the opening to press the recessed button for over 2 seconds.
Note: Switches that are part of stack will retain the stacking configuration.
GS752TXS Description
This section describes the smart switch hardware features.
GS752TXS Front Panel and Back Panel Configuration
The GS752TXS has 48 10/100/1000-Mbps copper ports and 4 dedicated
1000 Mbps/10 Gbps SFP+ fiber ports. Up to 2 fiber ports (port 51 and 52) at a time can be
used as stacking ports.

(ports 51 and 52) can be used at a time as stacking ports.
Reset Button
The smart switch has a Reset button on the front panel to allow you to manually reboot the
switch. This action is equivalent to powering the unit off and back on. The last saved
configuration is loaded into the switch as it resets. To use the Reset button, insert a device
such as a straightened paper clip into the opening to press the recessed button. The front
panel LEDs turn off and light again as the switch performs its power-on self-test (POST).
Factory Defaults Button
The smart switch has a Factory Defaults button on the front panel so that you can remove the
current configuration and return the device to its factory settings. When you press the Factory
Defaults button, all settings including the password, VLAN settings, and port configurations
are removed. To use the Factory Defaults button, insert a device such as a straightened
paper clip into the opening to press the recessed button for over 2 seconds.
Note: Switches that are part of stack will retain the stacking configuration.

3. Applications
Your GS728TXS/GS752TXS Smart Switch is designed to provide flexibility in configuring your
network connections. It can be used as your only network traffic-distribution device or with
10 Mbps, 100 Mbps, 1000 Mbps, and 10-Gbps hubs and switches. Topics include:
•Desktop Switching
•Backbone Switching

Desktop Switching
The smart switch can be used as a desktop switch to build a small network that enables
users to have 1000-Mbps access to a file server. With full duplex enabled, the switch port
connected to the server or computer can provide 2000 Mbps throughput. If a 10-Gbps
module is used to connect the switch to the file server in full-duplex operation, then the server
can provide up to 20 Gbps throughput. (The figure shows the GS752TXS Smart Switch;
however, the GS728TXS Smart Switch can also be used for desktop switching.)

Backbone Switching
You can use the smart switch as a backbone switch in a small network that gives users
high-speed access to servers and other network devices. (The figure shows the GS752TXS
Smart Switch; however, the GS728TXS Smart Switch can also be used for backbone
switching.)
