GS752TXS Smart Switch Hardware Installation Guide
Overview
The NETGEAR GS752TXS Smart Switch provides 48 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 NETGEAR GS752TXS Smart Switch also provides the benefit of administrative
management with a complete package of features for the observation, configuration, and
control of the network. With a Web-based Graphical User Interface (GUI), the switch’s many
capabilities can be viewed and used in a simple and intuitive manner. 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 traffic
prioritization. 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 PC.
The NETGEAR GS752TXS Smart Switch can be free standing, 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.
This capability makes the switch ideal for environments that have a mix of Ethernet, Fast
Ethernet, Gigabit Ethernet, or 10 Gigabit Ethernet devices. In addition, 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 named 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 the Stacking setup, the switches will auto-select one as the Stacking Master. All other
devices are named as slave stack members, and assigned a unique Unit ID. 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 in the event of failure of the stack master. 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.
Switch software is downloaded separately for each stack member. However, all units in the
stack must be running the same software version.

GS752TXS Smart Switch Hardware Installation Guide
A stack unit can operate in one of the following Modes:
•
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 above, and in addition, it
continuously monitors the existence and operation of the stack master. If the master unit
fails, the master-backup unit will assume the stack-master role. (“Switchover”).
A slave unit only runs 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.

Device Hardware Interfaces
RJ-45 Ports
RJ-45 ports are autosensing ports. When inserting 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 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 inserting 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 connecting the port to a PC) or an “uplink” connection (such as when connecting
the port to a router, switch, or hub).
•
Configures the RJ-45 port to enable communications with the attached device, without
requiring user intervention. In this way, the Auto Uplink technology compensates for
setting uplink connections, while eliminating concern about whether to use crossover or
straight-through cables when attaching devices.
SFP+ Ports
To enable you to have fiber connections on your network, there are four SFP+ ports (49
through 52) that 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 51 and 52) can be used at a time as stacking ports.

GS752TXS Smart Switch Hardware Installation Guide
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 operate the Reset button, insert a
device such as a paper clip into the opening to press the recessed button. The front-panel
LEDs should extinguish 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 operate the Factory Defaults button, insert a device such as a
paper clip into the opening to press the recessed button for over two seconds.
Note: Switches that are part of stack will retain the stacking configuration.

Step 6: Installing Device as Stand-alone or Stack Master
A master-backup unit runs as a slave unit as described above. In addition, it continuously
monitors the existence and operation of the stack master. If the master unit fails, the
master-backup unit will assume the stack-master role (“Switchover”). In the default
configuration, the master and backup switches are assigned unit ID 1 and 2, respectively;
however, the administrator may use the Web interface to assign different unit IDs. The goal
for switchover time is under 30 seconds.
If a stacking cable fails or a stack unit is extracted in a chain topology, slave units could be
disconnected from the stack (which puts them in an ambiguous state), and they will set all
their ports to the down state.
Each unit may work in one of two modes: Stand-alone, or Stack mode. The operational mode
is determined at software boot time, and can only be changed by a unit reset. The 7-segment
stacking ID LED remains illuminated in both modes.
The device supports two stacking topologies: Ring topology or Chain topology.

Figure 9. Stacking Topologies
The device is “Plug and Play” in terms of stacking configuration. Before powering up the
device, connect the devices into the required stacking topology. Then power up the devices.
By default, the switch is configured to allow the master and slave designations to be
determined through automatic discovery. You can use the web interface to configure the
stack to select a particular switch as master after the device has been booted and is
operational (see the System > Stacking page).
For more information on stacking see the Software Administration Manual. A link to this
document is on your Resource CD.
Step 7: Applying AC Power
The GS752TXS Smart Switch does not have an ON/OFF switch. Power is controlled by the
power cord connection.
Before connecting the power cord, select an AC outlet that is not controlled by a wall switch,
which can turn off power to the switch. After selecting an appropriate outlet, use the following
procedure to apply AC power:
1. Connect the end of the power connection cable to the power receptacle on the back of
the switch.
2. Connect the AC power connection cable into a power source such as a wall socket or
power strip.
When you apply power, the Power LED on the switch’s front panel illuminates.
If the Power LED does not go on, check that the power cable is plugged in correctly and that

Step 8: Managing the Switch using a Web Browser or the
PC Utility
The GS752TXS Smart Switch contains software for viewing, changing, and monitoring the
way it works. This management software is not required for the switch to work. The ports can
be used without using the management software. However, the management software
enables the setup of VLAN and trunking features and also improves the efficiency of the
switch, which results in the improvement of its overall performance as well as the
performance of the network.
After powering up the switch for the first time, the Smart Switch can be configured using a
Web browser or a program called Smart Control Center. For more information about
managing the switch, see the Software Administration Manual on the Smart Switch Resource
CD.
Note: The switch is configured with a default IP address of 192.168.0.239
and a subnet mask of 255.255.255.0.

Manual for information about using the Web interface.
Additional Troubleshooting Suggestions
If the suggestions in Troubleshooting Chart do not resolve the problem, refer to the
troubleshooting suggestions in this section.
Network Adapter Cards
Ensure the network adapter cards installed in the PCs are in working condition and the
software driver has been installed.
Configuration
If problems occur after altering the network configuration, restore the original connections
and determine the problem by implementing the new changes, one step at a time. Ensure
that cable distances, repeater limits, and other physical aspects of the installation do not
exceed the Ethernet limitations.
Switch Integrity
If required, verify the integrity of the switch by resetting the switch. To reset the switch,
remove the AC power from the switch and then reapply AC power. If the problem continues,
contact NETGEAR technical support. In North America, call 1-888-NETGEAR. If you are
outside of North America, please refer to the support information card included with your
product.
Auto-Negotiation
The RJ-45 ports negotiate the correct duplex mode, speed, and flow control if the device at
the other end of the link supports auto negotiation. If the device does not support auto
negotiation, the switch determines only the speed correctly, and the duplex mode defaults to
half-duplex.
