The GS700TS 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 Webbased 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
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 GS700TS 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.

10/100/1000 ports are supported in a stack
Introduction
1-16
v1.0, November 2007
GS700TS Hardware Installation Guide
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 member, but can become
a stack master in the event of failure of stack master. The master and backup master are assigned
unit IDs of 1 and 2. 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 members. However, all units in the stack
must be running the same software version.
A device can operate in one of the following modes:
•
Stand-alone – The unit runs as a general switch and does not run the stacking application.
•
Master Unit – Manages the Stack and is responsible for the configuration.
•
Master-Backup – Runs as a slave unit and monitors the operation of the stack master. If the
master unit fails, the Master-Backup automatically assumes the Stack-Master role. If a MasterBackup becomes the Master Unit, another Master-Backup will need to be selected manually.
One of the Slave units will not automatically become a Master-Backup.
•
Slave – Runs a slave version of the Switching Algorithm, which allows the applications
running on the master unit to control the resources of the slave unit.

2-33
Installation
v1.0, November 2007
GS700TS Hardware Installation Guide
Figure 2-4
The device is “Plug and Play” in terms of stacking connection and configuration. Before powering
up the device, connect the devices into the required stacking topology. The Stacking Master and
slave designations are configured through automatic discovery. Manually changing the stacking
configuration is through switch web page once the device has been booted and is operational.
For more information on stacking see the NETGEAR Smart Switch User Guide.
Step 7: 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.
Installation
2-34
v1.0, November 2007
GS700TS Hardware Installation Guide
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 8: 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.

Device Hardware Interfaces
This section provides information for the following hardware interfaces:
•
RJ-45 Ports
•
SFP GBIC Module
•
Factory Defaults Button
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).
Physical Description
3-23
v1.0, November 2007
GS700TS Hardware Installation Guide
•
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 straightthrough 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.

Symptom
Cause
Solution
A segment or device is
not recognized as part of
the network.
One or more devices are
not properly connected,
or cabling does not meet
Ethernet guidelines.
Verify that the cabling is correct. Ensure all
connectors are securely positioned in the required
ports. Equipment may have been accidentally
disconnected.
ACT LED is flashing
continuously on all
connected ports and the
network is disabled.
A network loop
(redundant path) has
been created.
Break the loop by ensuring that there is only one
path from any networked device to any other
networked device.
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.
