1. Introduction
Congratulations on the purchase of your NETGEAR® ProSafeTM GS752TXS Smart Switch! Your
GS752TXS 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 48
twisted-paired ports on the front panel of the switch which support nonstop 10/100/1000
networks. The front panel also has four 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.
The

GS752TXS Smart Switch Hardware Installation Guide
Overview
The NETGEAR GS752TXS Smart Switch provides 48 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 NETGEAR GS752TXS 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 GS752TXS 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, Gigabit Ethernet, or 10 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 the GS752TXS Smart Switch:
• Forty-eight 10/100/1000 Mbps auto-sensing Gigabit-Ethernet switching ports.
• Four dedicated 1000M/10G SFP+ fiber ports.
• Full NETGEAR Smart Switch functionality.
• Full compatibility with IEEE standards:
• IEEE 802.3i (10BASE-T)
• IEEE 802.3u (100BASE-TX)
• IEEE 802.3ab (1000BASE-T)

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.
• Standard NETGEAR 7xx series chassis.
• NETGEAR Green product series power-saving features:
• Automatic power consumption adjustment based on the RJ-45 cable length.
• 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 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.

GS752TXS Smart Switch Hardware Installation Guide
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.
• 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.
