Introduction  
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 GS700TP Smart Switch and provides the following  
information:  
Overview  
Switch Features  
Package Contents  
Overview  
This Installation Guide is for the following NETGEAR Smart Switches:  
GS724TP - This product offers support for 24 ports of 10/100/1000 and two Form-factor slots  
which support 1000 (1000Base-SX/LX)/100M SFP. This product supports the added feature of  
Power over Ethernet (PoE).  
GS748TP - This product offers support for 48 ports of 10/100/1000 and four Form-factor slots  
which support 1000 (1000Base-SX/LX)/100M SFP. This product supports the added feature of  
Power over Ethernet (PoE).  
You can make high-speed connections using the Gigabit ports. For example:  
Connecting to a network backbone  
Linking to high-speed servers  
Providing 10/100/1000 copper and fiber connectivity  
The GS700TP 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), you can view the switch’s many features and use them in a  
simple and intuitive manner. The switch’s management features include configuration for port and

GS700TP Hardware Installation Guide  
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 SmartWizard Discovery  
program, a utility that runs on a PC.  
The GS700TP 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- 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.  
The NETGEAR Smart Switch can be used as a desktop to build a small network that enables you  
to have 1000 Mbps access to a file server. With full-duplex enabled, the switch port connected to  
the server or PC can provide 2000 Mbps throughput.

40ºC (32 and 104ºF). 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.  
Step 2: Installing the Switch  
The NETGEAR Smart Switch can be installed on a flat surface or in a standard 19-inch rack.  
Installing the Switch on a Flat Surface  
The switch ships with four self-adhesive rubber footpads. Stick one rubber footpad on each of the  
four concave spaces on the bottom of the switch. The rubber footpads cushion the switch against  
shock/vibrations.  
Installing the Switch in a Rack  
To install the switch in a rack, use the following procedure (and refer to Figure 2-1). To perform  
this procedure, you need the 19-inch rack-mount kit supplied with switch.  
1. Attach the supplied mounting brackets to the side of the switch.  
2. Insert the screws provided in the rack-mount kit through each bracket and into the bracket  
mounting holes in the switch.  
3. Tighten the screws with a #1 Phillips screwdriver to secure each bracket.  
4. Align the mounting holes in the brackets with the holes in the rack, and insert two pan-head  
screws with nylon washers through each bracket and into the rack.

Step 4: Connecting Devices to the Switch  
The following procedure describes how to connect PCs to the switch’s RJ-45 ports. The  
NETGEAR Smart Switch contains Auto Uplink™ technology, which allows you to attach devices  
using either straight-through or crossover cables..  
Figure 2-2  
Connect each PC to an RJ-45 network port on the Switch front panel (Figure 2-2). Use Category 5  
(Cat5) Unshielded Twisted-Pair (UTP) cable terminated with an RJ-45 connector for these  
connections.  
Note: Ethernet specifications limit the cable length between the switch and the attached  
device to 100 m (328 ft.).  
Step 5: Installing an SFP GBIC Module  
The following procedure describes how to install an SFP Gigabit Ethernet module in the switch’s  
Gigabit module bay. Standard SFP GBIC modules are sold separately from the Smart Switch. If  
you do not plan to install an SFP GBIC module at this time, skip this procedure.  
Installation

GS700TP Hardware Installation Guide  
To install an SFP GBIC module:  
1. Insert the SFP module into the SFP module bay.  
2. Press firmly to ensure the module seats into the connector  
Figure 2-3  
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 a grounded 3-pronged AC source that is not controlled by a wall switch, which can turn off  
power to the switch. After selecting an appropriate AC source, 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 the 3-pronged AC source.  
When applying power, the Power LED on the switch’s front panel is green.  
If the Power LED does light up, check that the power cable is plugged in correctly and that the  
power source is functioning correctly. If this does not resolve the problem, refer to Appendix A  
“Troubleshooting”.

Step 7: Managing the Switch through a Web Browser or the  
PC Utility for Initial Configuration  
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. You can use the ports  
without using the management software. However, the management software enables you to setup  
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, you can configure the Smart Switch using a Web  
browser or a utility program called SmartWizard Discovery. For more information about managing  
the switch, see the Software 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.

RJ-45 Ports  
RJ-45ports are auto-sensing ports. When inserting a cable into an RJ-45 port, the switch  
automatically ascertains the maximum speed (10 or 100 or 1000 Mbps) and duplex mode (half- 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.  
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 becomes  
active.  
The SFP GBIC bay accommodates a standard SFP GBIC module.  
Factory Defaults Button  
The Smart Switch has a Factory default button to enable clearing the current configuration and  
returning the device back to the factory settings. This removes all settings, including the password,  
VLAN settings and port configurations.

Check the crimp on the connectors and make sure  
that the plug is properly inserted and locked into the  
port at both the switch and the connecting device.  
Ensure all cables are used correctly and comply with  
the Ethernet specifications. Check for a defective  
adapter card, cable, or port by testing them in an  
alternate environment where all products are  
functioning.

Additional Troubleshooting Suggestions  
If the suggestions in Troubleshooting Chart do not resolve the problem, refer to the  
troubleshooting suggestions in this section.  
Network Adapter Cards  
Ensure the network adapter cards installed in the PCs are functioning correctly and the latest  
software driver has been installed.  
Configuration  
If problems occur after altering the network configuration, restore the original connections and  
determine the problem by implementing the new changes, one step at a time. Ensure that cable  
distances, repeater limits, and other physical aspects of the installation do not exceed the Ethernet  
limitations.  
Switch Integrity  
If required, verify the integrity of the switch by resetting the switch. To reset the switch,  
disconnect the AC power from the switch and then reconnect AC source. If the problem continues,  
contact NETGEAR technical support. In North America, call 1-888-NETGEAR. If you are outside  
of North America, please refer to the support information card included with your product.

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.
