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.

•4 dedicated 1000M/10G SFP+ fiber ports.

•Full NETGEAR Smart Switch functionality.

•Full compatibility with IEEE standards:

-IEEE 802.3i (10BASE-T)

-IEEE 802.3x (Full-duplex flow control)

•AutoSensing and autonegotiating capabilities for all ports.

•Auto Uplink™ on all ports to make the right connection.

•Automatic address learning function to build the packet-forwarding information table. The

table contains up to 16K Media Access Control (MAC) addresses.

•Store-and-forward transmission to remove bad packets from the network.

•Full-duplex IEEE 802.3x pause frame flow control.

•Active flow control to minimize packet loss and frame drops.

•Half-duplex backpressure control.

•Per port LEDs and power LED.

•Internal open frame power supply.

-Automatic power consumption adjustment based on the RJ-45 cable length

(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.
