1. Introduction
Congratulations on the purchase of your NETGEAR®ProSafeTM GS728TS, GS728TPS,
GS752TS, or GS752TPS Smart Switch! Your Smart Switch is a state-of-the-art,
high-performance, IEEE-compliant network solution designed for users who require a large
number of ports and want the power of Gigabit connectivity to eliminate bottlenecks, boost
performance, and increase productivity. There are either 24 (GS728TS and GS728TPS) or 48
(GS752TS and GS752TPS) twisted-pair ports on the front panel of the switch which support
nonstop 10/100/1000 networks. The front panel also has six SFP ports, 2 of which are combo
ports, 2 are dedicated 1000M ports, and the last 2 ports can be used for 1000M uplink or 2.5
Gbps stacking.
The GS728TS, GS728TPS, GS752TS, and GS752TPS Smart Switch Hardware 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 provides the following
information:

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.

The following list identifies the key features of the Smart Switch:
• Interfaces:
• GS728TS/GS752TS
• 24/48 x 10/100/1000 Mbps copper ports.

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.

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.
