1. Introduction
Congratulations on the purchase of your NETGEAR®ProSafeTM GS752TP, GS728TP, and
GS728TPP Gigabit Smart Switch. Your GS752TP, GS728TP, and GS728TPP Gigabit Smart
Switch is a state-of-the-art, high-performance, IEEE-compliant network solution designed for
users who require many ports and want the power of gigabit connectivity to eliminate
bottlenecks, boost performance, and increase productivity. The front panel of the switch has 24
or 48 twisted-paired ports that support nonstop 10/100/1000 networks. The front panel also has
4 SFP ports that support 1000M optical modules. To simplify installation, the switch is shipped
ready for use out of the box.
The GS752TP, GS728TP, and GS728TPP Gigabit Smart Switches Hardware Installation Guide
describes how to install and power on the GS752TP, GS728TP, and GS728TPP Gigabit Smart
Switch. The information in this manual is intended for readers with intermediate computer and
Internet skills.
This chapter serves as an introduction to the GS752TP, GS728TP, and GS728TPP Gigabit
Smart Switch and provides the following information:

GS752TP, GS728TP, and GS728TPP Gigabit Smart Switch
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
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.
Features
The following list identifies the key features of these switches:
•48 or 24 10/100/1000 Mbps AutoSensing Gigabit Ethernet switching ports.

GS752TP, GS728TP, and GS728TPP Gigabit Smart Switch
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.

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.

3. Applications
Your GS752TP, GS728TP, and GS728TPP Gigabit 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, and 1000 Mbps hubs and switches.
Desktop Switching
The GS752TP, GS728TP, and GS728TPP Gigabit 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 mode enabled, the switch port connected to the server or computer can provide
2000 Mbps throughput.
