1. Introduction
Congratulations on the purchase of your NETGEAR®ProSafeTM GS728TXS/GS752TXS Smart
Switch! Your GS728TX/GS752TXS 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.
There are either 24 (GS728TXS) or 48 (GS752TXS) twisted-pair ports on the front panel of the
switch that support nonstop 10/100/1000 networks. The front panel also has 4 SFP+ ports that
support 1000M and 10G optical modules or up to two stacking modules. To simplify installation,
the switch is shipped ready for use out of the box.
This installation guide describes how to install and power on the 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 smart switch and includes the following sections:

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.
Features
The following lists the key features of the smart switch:
•24 (GS728TXS) or 48 (GS752TXS) 10/100/1000-Mbps autosensing Gigabit Ethernet
switching ports.

(GS752TXS only)
-Per port automatic power down when the port link is down.
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.

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.
