Introduction  
Congratulations on the purchase of the NETGEAR Smart Switch. The NETGEAR 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. To simplify installation, the switch is  
shipped ready for use out of the box.  
This chapter serves as an introduction to the Smart Switch and provides the following information:  
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, and Class of  
1-1

GS716T/GS724T Hardware Installation Guide  
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 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 twisted-pair (UTP)  
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.

GS716T/GS724T Hardware Installation Guide  
Determines whether the link to the attached device requires a “normal” connection (such as  
when connecting the port to a PC) 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.

Figure 4-3  
Step 6: Applying AC Power  
NETGEAR Smart Switch does not have an ON/OFF switch. The method of applying or removing  
AC power is by connecting or disconnecting the power cord. Before connecting the power cord,  
select an AC outlet that is not controlled by a wall switch, which can turn off power to the switch.  
After selecting an appropriate outlet, use the following procedure to apply AC power.  
1. Connect the female end of the supplied AC power adapter cable to the power receptacle on the  
back of the switch.  
2. Connect the 3-pronged end of the AC power adapter cable to a grounded 3-pronged AC outlet.  
When applying power, the Power LED on the switch’s front panel is Green.  
If the Power LED does not go on, check that the power cable is plugged in correctly and that the  
power source is good. If this does not resolve the problem, refer to Appendix A .

Step 7: Managing the Switch using a Web Browser or the PC  
Utility  
The NETGEAR Smart Switch contains software for viewing, changing, and monitoring the way it  
works. This management software is not required for the switch to work. The ports can be used  
without using the management software. However, the management software enables the setup of  
VLAN and Trunking features, and also improves the efficiency of the switch, which results in the  
improvement of its overall performance as well as the performance of the network.  
After powering up the switch for the first time, the Smart Switch can be configured using a Web  
browser or a utility program called SmartWizard Discovery. For more information about  
managing the switch, see the GS716T/GS724T Series Software Administration Manual on the  
Smart Switch Resource CD.  
Note: When the device powers up, there is a default IP address already configured on the  
device. The default IP address is 192.168.0.239 and subnet mask 255.255.255.0.

Auto-Negotiation  
The RJ-45 ports negotiate the correct duplex mode and speed if the device at the other end of the  
link supports auto negotiation. If the device does not support auto negotiation, the switch only  
determines the speed correctly and the duplex mode defaults to half-duplex.  
The gigabit port on the Gigabit module negotiates speed, duplex mode, and flow control, provided  
that the attached device supports auto-negotiation.
