GS716T/GS724T Gigabit Smart Switch
Overview
This Installation Guide is for the following NETGEAR Smart Switches:
•GS716T – This product offers support for 16 ports of 10/100/1000 Mbps and two
Form-factor slots, which support 1000 (1000BASE-SX/LX)/100 Mbps Small Form-factor
Pluggable (SFP).
•GS724T – This product offers support for 24 ports of 10/100/1000 and two Form-factor
slots, which support 1000 (1000BASE-SX/LX)/100 Mbps SFP.
Using Gigabit ports, high-speed connections can be made to a server or network backbone.
For example:
•Linking to high-speed servers
•Providing 10/100/1000 Mbps copper and fiber connectivity
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. 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, IPv6 Management support to enable IPv6 operation over the network
port, IPv6 QoS, IPv6 ACL 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.
The Smart Switch can be free-standing, 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, but
much longer for fiber connections using SFP GBIC modules.

Device Hardware Interfaces
RJ-45 Ports
RJ-45 ports are auto-sensing ports. When inserting a cable into an RJ-45 port, the switch
automatically ascertains the maximum speed (10, 100, or 1000 Mbps) and duplex mode
(half-duplex or full-duplex) of the attached device. All ports support only unshielded or
shielded twisted-pair (UTP or STP) cable terminated with an 8-pin RJ-45 plug.
To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink. This
technology allows attaching devices to the RJ-45 ports with either straight-through or
crossover cables. When inserting a cable into the switch’s RJ-45 port, the switch
automatically:
•Senses whether the cable is a straight-through or crossover cable.
•Determines whether the link to the attached device requires a “normal” connection (such
as when connecting the port to a computer) or an “uplink” connection (such as when
connecting the port to a router, switch, or hub).
•Configures the RJ-45 port to enable communications with the attached device, without
requiring user intervention. In this way, the Auto Uplink technology compensates for
setting uplink connections, while eliminating concern about whether to use crossover or
straight-through cables when attaching devices.
SFP GBIC Module
The GBIC module bays accommodate standard SFP GBIC modules, such as the AGM731F,
AGM732F, or AGM733 from NETGEAR, allowing fiber connections on the network. The
module bay is a combo port, sharing a connection with an RJ-45 port. Being a combo port,
only one type of connection can be active at any given time. For example, both copper and
fiber port cannot be used at the same time. If both connectors are plugged in at the same
time, the fiber port will be active.
The SFP GBIC bay accommodates a standard SFP GBIC module.
Factory Defaults Button
The Smart Switch has a Factory Default button so that you can remove the current
configuration and return the device to its factory settings. When you enable the Factory
Default button, all settings, including the password, VLAN settings and port configurations will
be removed.

3. Applications
Your NETGEAR Smart Switch is designed to provide flexibility in configuring your network
connections. It can be used as a stand-alone device or with 10 Mbps, 100 Mbps, and 1000
Mbps hubs and switches.

16
GS716T/GS724T Gigabit Smart Switch
Desktop Switching
The NETGEAR Smart Switch can be used as a desktop switch to build a small network that
enables users to have 1000 Mbps access to a file server. With full-duplex enabled, the switch
port connected to the server or computer can provide 2000 Mbps throughput.

Step 1: Prepare the Site
Before you install the switch, ensure the operating environment meets the operating
environment requirements in the following table.
Table 3. Site Requirements
Characteristics Requirements
Mounting •Desktop installations - Provide a flat table or shelf surface.
•Rack-mount installations - Use a 17-inch (48.3-centimeter) EIA standard
equipment rack that is grounded and physically secure. The rack-mount kit supplied
with the switch is also required.
Access Locate the switch in a position that allows access to the front panel RJ-45 ports, view the
front panel LEDs, and access power connector.
Power source Provide a power source within 6 feet (1.8 meters) of the installation location. Power
specifications for the switch are shown in
Appendix A . Ensure the AC outlet is not
controlled by a wall switch, which can accidentally turn off power to the outlet and the
switch.
Environmental •Temperature - Install the switch in a dry area, with ambient temperature between 0
and 55ºC (32 and 131ºF). Keep the switch away from heat sources such as direct
sunlight, warm air exhausts, hot-air vents, and heaters.
•Operating humidity - The installation location should have a maximum relative
humidity of 90%, non-condensing.
•Ventilation - Do not restrict airflow by covering or obstructing air inlets on the sides
of the switch. Keep at least 2 inches (5.08 centimeters) free on all sides for cooling.
Be sure there is adequate airflow in the room or wiring closet where the switch is
installed.
•Operating conditions - Keep the switch at least 6 ft. (1.83 m) away from nearest
source of electromagnetic noise, such as a photocopy machine.
