Overview
The NETGEAR GS752TP, GS728TP, and GS728TPP Gigabit Smart Switch provides 48 or
24 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 100M/1000M
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 100M/1000M fiber connectivity
These switches also provide 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 computer.
These switches can be freestanding, 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

Device Hardware Interfaces
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 does the following:
• 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).
• 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 you are attaching devices.
SFP Ports
To enable you to have fiber connections on your network, there are four SFP ports (49
through 52 or 25 through 28) that accommodate standard 100M/1000M transceiver modules,
which are sold separately.
16
Page 17
GS752TP , GS728TP, and GS728TPP Gigabit Smart Switch
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 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 operate the Factory Defaults button, insert a device such as
a paper clip into the opening to press the recessed button for over 2 seconds.
Select Button
LED Mode Select button on the front panel enables you to 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.

Step 4: Connect Devices to the Switch
The following procedure describes how to connect computers to the switch’s RJ-45 ports.
The switch contains Auto Uplink technology, which allows the attaching of devices using
either straight-through or crossover cables.
Figure 11. Connecting devices to the switch
Connect each computer to an RJ-45 network port on the switch front panel (Figure 11). Use a
Category 5 (Cat 5) 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 100 meters (328 feet).
Step 5: Install 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.
24
Page 24
GS752TP , GS728TP, and GS728TPP Gigabit Smart Switch
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. You can install up to three more
Gigabit Ethernet modules using this procedure.
Figure 12. Installing and SFP transceiver module
Step 6: Apply AC Power
The GS752TP, GS728TP, and GS728TPP Gigabit 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
power strip.
When you apply power, the Power LED on the switch’s front panel lights.
If the Power LED does not light, 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,
Troubleshooting.
AC power connection cable into a power source such as a wall socket or
Step 7: Apply RPS DC Power
This step is applicable to the GS728TPP only. Plug in the external RPS power supply to the
RPS connector on the back panel.

Step 8: Manage the Switch Using a Web Browser or the Computer Utility
The GS752TP, GS728TP, and GS728TPP Gigabit Smart Switch contains software for
viewing, changing, and monitoring the way it works. This management software is not
required for the switch to work. You can use the switch 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.

Troubleshooting Chart
The following table lists symptoms and causes of, and solutions to possible problems.
Symptom Cause Solution
Power LED is off. No power is received. Check the power cord connections and the connected
device. Ensure that 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.
ACT LED is blinking
continuously on all
connected ports and the
network is disabled.
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.
A network loop
(redundant path) has
been created.
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 that
all cables used are correct and comply with Ethernet
specifications. Check for a defective computer adapter
card, cable, or port by testing them in an alternate
environment where all products are functioning.
Make sure that the attached device is set to
auto-negotiate.
Verify that the cabling is correct. Ensure that all
connectors are securely positioned in the required
ports. Equipment might have been accidentally
disconnected.
Break the loop by ensuring that there is only one path
from any networked device to any other networked
device.
interface, you can configure the Spanning Tree
Protocol (STP) to prevent network loops.
After you connect to the switch management
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 that the network adapter cards installed in the computers are in working condition and
the software driver has been installed.
Configuration
If problems occur after you alter the network configuration, restore the original connections
and determine the problem by implementing the new changes, one step at a time. Ensure
28
Page 28
GS752TP , GS728TP, and GS728TPP Gigabit Smart Switch
that cable distances, repeater limits, and other physical aspects of the installation do not
exceed the Ethernet limitations.
Switch Integrity
If necessary, 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.
Autonegotiation
The RJ-45 ports negotiate the correct duplex mode, speed, and flow control if the device at
the other end of the link supports autonegotiation. If the device does not support
autonegotiation, the switch determines only the speed correctly, and the duplex mode
defaults to half-duplex.
