For example:

• Connect switches to each other with high-speed links

• Linking to high-speed servers

• Providing 10/100/1000 Mbps copper and fiber connectivity

These Smart 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, 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 these switches on
the network requires the Smart Control Center program, a utility that runs on a computer.

These Smart Switches 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

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. GS716T,
GS724T and GS748T all have two dedicated SFP ports (the last two ports). Moreover,
GS748T has two combo ports (port 47 and 48), which are sharing SFP GBIC with RJ-45
ports. 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.

Step 6: Apply AC Power

NETGEAR GS716T,GS724T,GS748T Series 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

Troubleshooting Chart.

Step 7: Manage the Switch using a Web Browser or the Smart Control Center Utility

The NETGEAR GS716T,GS724T,GS748T Series 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 Smart Control Center. For more information about
the Smart Control Center, visit

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.

Table 5. Troubleshooting Chart

Symptom Cause Solution

Power LED is off. No power is received. Check the power cord connections for the switch at

the switch and the connected device. Ensure all
cables used are correct and comply with Ethernet
specifications.

Link LED is off or
intermittent.

File transfer is slow or
performance
is a problem.

A segment or device is
not recognized as part of
the network.

ACT LED is flashing
continuously on all
connected ports and the
network is disabled.

degradation

Port connection is not
working.

Half-duplex or full-duplex
setting on the switch and
the connected device are
not the same.

One or more devices are
not properly connected,
or cabling does not meet
Ethernet guidelines.

A network loop
(redundant path) has
been created.

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 used are correct and comply with
Ethernet specifications. Check for a defective
adapter card, cable, or port by testing them in an
alternate environment where all products are
functioning.

Make sure the attached device is set to
auto-negotiate.

Verify that the cabling is correct. Ensure all
connectors are securely positioned in the required
ports. Equipment may have been accidentally
disconnected.

Break the loop by ensuring that there is only one
path from any networked device to any other
networked device.

Troubleshooting Hardware Installation Guide29

GS716T, GS724T and GS748T Gigabit Smart Switch

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 computers are in working condition and the
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,
remove the AC power from the switch and then reapply AC power. 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.
