GS728TS, GS728TPS, GS752TS, and GS752TPS Smart Switch Hardware Installation Guide
Overview
The NETGEAR GS728TS, GS728TPS, GS752TS, or GS752TPS Smart Switch provides
either 24 (GS728TS and GS728TPS) or 48 (GS752TS and GS752TPS) twisted-pair ports
that support nonstop 10/100/1000M networks. The switch also has six built-in Small Form
Factor Pluggable (SFP) GBIC slots, 2 of which are combo ports, 2 of which are dedicated
1000M ports, and the last 2 ports can be used for 1000M uplink or 2.5 Gbps stacking.
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 100M/1000M 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 GS728TS, GS728TPS, GS752TS, or GS752TPS 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 GS728TS, GS728TPS, GS752TS, or GS752TPS 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, or 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.
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.
Chapter 1. Introduction | 9
GS728TS, GS728TPS, GS752TS, and GS752TPS Smart Switch Hardware Installation Guide
• 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 detects 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 6 SFP ports that
accommodate standard 100M or 1000M transceiver modules, which are sold separately.
• 2 combo ports to support 10/100/1000 Mbps copper or 100M/1G optical module.
• 2 dedicated SFP ports to support 1G optical module.
• 2 dedicated SFP ports to support 1G optical module (uplink) or 2.5G stacking (via
stacking cable).
The last two SFP ports can alternatively be used to connect the switch with a 2.5G direct
attach cable to a stack. Up to two ports (ports 27 and 28 or 51 and 52) can be used at a time
as stacking ports.
Chapter 2. Physical Description | 19
GS728TS, GS728TPS, GS752TS, and GS752TPS Smart Switch Hardware Installation Guide
Note: Direct attach cable AGC761 (2.5G) is recommended to be used as a
stacking cable. The AGC761 cable is sold separately.
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.
Select Button
The Smart Switch GS728TP and GS752TP have a LED Mode Select button on the front
panel so that you can change the LED mode of the ports between Ethernet and PoE status.
You need to press the button for more than 1 second to change the LED mode.

GS728TS, GS728TPS, GS752TS, and GS752TPS Smart Switch Hardware Installation Guide
Step 1: Preparing the Site
Before you install the switch, ensure the operating environment meets the site requirements in
the following table.
Characteristics Requirements
Mounting • Desktop installations - Provide a flat table or shelf surface.
• Rackmount installations - Use a 19-inch (48.3-centimeter) EIA standard equipment rack that
is grounded and physically secure. The rackmount kit supplied with the switch is also required.
Access Locate the switch in a position that allows you to access the front-panel RJ-45 ports, view the
front-panel LEDs, and access the power connector.
Power source Provide a power connection cord. Power specifications for the switch are shown in Appendix A.
Ensure the AC outlet is not controlled by a wall switch, which can accidentally turn off power to
the outlet and the switch.
Environmental • Temperature - Install the switch in a dry area, with ambient temperature between 0 and 50ºC
(32ºF and 122ºF). Keep the switch away from heat sources such as direct sunlight, warm air
exhausts, hot-air vents, and heaters.
• Operating humidity - The installation location should have a maximum relative humidity of 10
to 90%, non-condensing.
• Ventilation - Do not restrict airflow by covering or obstructing air inlets on the sides of the
switch. Keep at least 2 inches (5.08 centimeters) free on all sides for cooling. Be sure there is
adequate airflow in the room or wiring closet where the switch is installed.
• Operating conditions - Keep the switch at least 6 ft. (1.83 meters) away from nearest source
of electromagnetic noise, such as a photocopy machine.
Step 2: Installing the Switch
The GS728TS, GS728TPS, GS752TS, and GS752TPS Smart Switch can be used on a flat
surface or mounted in a standard network equipment rack.
Installing the Switch on a Flat Surface
The switch ships with four self-adhesive rubber footpads. Stick one rubber footpad on each of
the four concave spaces on the bottom of the switch. The rubber footpads cushion the switch
against shock and vibrations. They also provide ventilation space between stacked switches.
Installing the Switch in a Rack
To install the switch in a rack, you need the 19-inch rackmount kit supplied with the switch.
1. Attach the supplied mounting brackets to the side of the switch.
2. Insert the screws provided in the rackmount kit through each bracket and into the bracket
mounting holes in the switch.
3. Tighten the screws with a #1 Phillips screwdriver to secure each bracket.
Chapter 4. Installation | 25

Figure 13. Connecting Devices to the Switch
SFP
+
Connect each PC to an RJ-45 network port on the Switch front panel (Figure 13). Use
Category 5 (Cat5) Unshielded Twisted-Pair (UTP) cable terminated with an RJ-45 connector
to make these connections.
Note: Ethernet specifications limit the cable length between the switch and
the attached device to 100m (328 ft.).
Step 5: Installing an SFP Transceiver Module
The following procedure describes how to install an optional SFP transceiver module into one
of the SFP ports of the switch.
Note: Contact your NETGEAR sales office to buy these modules. If you do
not want to install an SFP module, skip this procedure.
To install an SFP transceiver, insert the transceiver into the SFP port. Press firmly on the
flange of the module to seat it securely into the connector.
Chapter 4. Installation | 27

Figure 14. Installing and SFP Transceiver Module (GS752TPS Shown)
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 time
cost for switchover 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.
Note: The direct attach cable AGC761 (2.5G) is recommended to be used
as a stacking cable. The AGC761 cable is sold separately.
28 | Chapter 4. Installation
GS728TS, GS728TPS, GS752TS, and GS752TPS Smart Switch Hardware Installation Guide
Figure 15. 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 GS728TS, GS728TPS, GS752TS, and GS752TPS 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
the power source is good. If this does not resolve the problem, refer to Appendix A.
Chapter 4. Installation | 29
GS728TS, GS728TPS, GS752TS, and GS752TPS Smart Switch Hardware Installation Guide
Step 8: Managing the Switch using a Web Browser or the PC Utility
The GS728TS, GS728TPS, GS752TS, and GS752TPS 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.

A. Troubleshooting
A
This chapter provides information about troubleshooting the NETGEAR Smart Switch. Topics
include the following:
• Troubleshooting Chart
• Additional Troubleshooting Suggestions
Troubleshooting Chart
The following table lists symptoms, causes, and solutions of possible problems.
Symptom Cause Solution
Power LED is off. No power is received. Check the power cord connections and the connected
device. Ensure all cables used are correct and comply
with Ethernet specifications.
Link LED is off or
intermittent.
File transfer is slow or
performance degradation
is a problem.
A segment or device is
not recognized as part of
the network.
Port connection is not
working.
Half-duplex or full-duplex
setting on the switch and
the connected device are
not the same.
One or more devices are
not properly connected,
or cabling does not meet
Ethernet guidelines.
Check the crimp on the connectors and make sure that
the plug is properly inserted and locked into the port at
both the switch and the connecting device. Ensure all
cables used are correct and comply with Ethernet
specifications. Check for a defective PC adapter card,
cable, or port by testing them in an alternate
environment where all products are functioning.
Make sure the attached device is set to
auto-negotiate.
Verify that the cabling is correct. Ensure all connectors
are securely positioned in the required ports.
Equipment may have been accidentally disconnected.
Appendix : Troubleshooting | 31
GS728TS, GS728TPS, GS752TS, and GS752TPS Smart Switch Hardware Installation Guide
Symptom Cause Solution
ACT LED is flashing
continuously on all
connected ports and the
network is disabled.
A unit is linked to a stack,
but does not join the
stack.
A network loop
(redundant path) has
been created.
The stacking ports of the
new unit are configured
differently from the stack,
or the unit is configured
as a stand-alone unit.
Break the loop by ensuring that there is only one path
from any networked device to any other networked
device. After you connect to the switch management
interface, you can configure the Spanning Tree
Protocol (STP) to prevent network loops.
Remove the unit from the stack. Use the Web
Management to configure the unit as a stackable unit,
with last two ports used as the stacking ports. Refer to
the Smart Switch Software Administration 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.
