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 and GS728TP. The first 8 ports are PoE+ providing 30 W of DC power, and the
remaining copper ports are PoE (Power over Environment) providing 15.4W of DC power.
•GS728TPP. All 24 copper ports are PoE+ providing 30 W of DC power. This model
includes an external power supply to support the increased power requirements.
•Four dedicated 100M/1000M 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)

•IEEE802.3af (DTE Power via MDI)
•IEEE802.3at (DTE Power via MDI Enhancements)
•IEEE802.3az (Energy Efficient Ethernet)
•IEEE 802.3x (Full-duplex flow control)
•AutoSensing and auto-negotiating 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 8K 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.
•LEDs. Power LED, FAN Status LED, LED Mode LED, Max PoE LED, and LEDs for each
port.
•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.
•IEEE802.3az, EEE (Energy Efficient Ethernet) compliance.
