ProSAFE 24-Port 10/100 Smart Switch with 2 Gigabit Ports FS726Tv2
Overview
This hardware installation guide is for the NETGEAR ProSAFE 24-Port 10/100 Smart Switch
with 2 Gigabit Ports FS726Tv2. The switch provides twenty-four 10/100BASE-T ports, two
10/100/1000BASE-T ports, one of which functions as a combo port, and one small
form-factor pluggable (SFP) GBIC slot that functions as a combo port.
You can make high-speed connections using the Gigabit Ethernet ports. For example:
•Connecting switches to each other with high-speed links
•Connecting to a network backbone
•Linking to high-speed servers
•Providing 10/100/1000 Mbps copper and 100/1000 Mbps fiber connectivity
Note: In this guide, the NETGEAR ProSAFE 24-Port 10/100 Smart Switch
with 2 Gigabit Ports FS726Tv2 is referred as the switch.
The switch also provides the benefit of administrative management with a complete package
of features to monitor, configure, and control the network. With the web management
interface, 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. Initial discovery of the switch on the network requires
the Smart Control Center, a utility that runs on a computer.
You can use the switch freestanding or rack-mounted in a wiring closet or equipment room.
The switch is IEEE-compliant and provides low latency for high-speed networking. All ports
can automatically negotiate to the highest speed. This capability makes the switch well suited
for environments that have a mix of Ethernet, Fast Ethernet, and 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 a Category 5 twisted-pair cable.
You can use the switch 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 computer can provide 2000 Mbps throughput.

Product Label
The product label on the back panel of the switch shows the hardware model number and
version, the software version, the unique MAC address, and the unique serial number. The
following figure shows a generic product label.
Figure 6. Generic product label
RJ-45 Ports
RJ-45 ports are autosensing ports. When you insert a cable into an RJ-45 port, the switch
automatically ascertains the maximum speed (10, 100, or 1000 Mbps) and duplex mode
(half- or full-duplex) of the attached device. All ports support a twisted-pair cable that is
terminated with an 8-pin RJ-45 plug.
To simplify the procedure for attaching devices, all RJ-45 ports support Auto MDI/MIDX. This
technology enables you to attach devices to the RJ-45 ports with either straight-through or
crossover cables. When you insert a cable into the switch’s RJ-45 port, the switch
automatically configures the RJ-45 port to enable communications with the attached device.
With Auto MDI/MIDX technology, you do not need to configure uplink connections, and you
do not need to think about whether to use crossover or straight-through cables when you
attach a device.

SFP GBIC Module
The SFP GBIC slot (26F) accommodates a standard SFP GBIC module to enable fiber
connections on the network. The SFP GBIC slot is a combo port, sharing a connection with
an RJ-45 combo port (26T).
Only one type of connection (copper or fiber) on the combo port can be active. If the RJ-45
copper combo port and the SFP fiber combo port both have devices connected, the device
that was connected first take precedence. In other words, the combo ports function on a
first-come, first-served basis.
The switch supports NETGEAR SFP GBIC modules such as the AGM731F and AGM732F.
Factory Defaults Button and Reset Button
The switch has a Defaults button to clear the configuration and return the switch to the factory
settings. Pressing the button for at least two seconds causes the switch to reboot with factory
settings. All custom settings are removed, including the password, VLAN settings, and port
configurations.
In addition, the switch has a Reset button. Pressing this button reboots the switch but does
not change its configuration.

2. Press firmly to ensure that the module seats into the slot.
Step 6: Apply AC Power
The switch does not have an On/Off switch. You apply AC power to the switch by connecting
the power cord, and you removeAC power from the switch by disconnecting the power cord.
Before you connect the power cord, select a grounded 3-pronged AC source that is not
controlled by a wall switch, which could turn off power to the switch.
To apply AC power to the switch:
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 you apply power, the Power LED on the front panel of the switch lights yellow. If the
Power LED does not light, check that the power cable is plugged in correctly and that the
power source is functioning correctly. If you cannot resolve the problem, see Chapter 3,
Troubleshooting.

Installation
17
ProSAFE 24-Port 10/100 Smart Switch with 2 Gigabit Ports FS726Tv2
Step 7: Manage the Switch through a Web Browser or
through the Smart Control Center
The switch contains management software that lets you view, change, and monitor the way
the switch functions. The management software is not required for the switch to function.You
can use the ports without using the management software. However, the management
software lets you configure VLAN and trunking features, and lets you improve the efficiency
of the switch, which results in the improvement of its overall performance as well as the
performance of the network.
After you have powered the switch for the first time, you can configure and manage the
switch by using either a web browser or the Smart Control Center utility. For information
about configuring and managing the switch, see the Software Administration Manual.
Note: If the switch cannot connect to a DHCP server, the switch uses
192.168.0.239 as its default IP address and 255.255.255.0 as its
default subnet mask.
Note: To access the web management interface, enter password as the
default password.

performance is degraded. Half- or full-duplex setting on the switch and the connected device
are not the same.
Make sure that the attached device is configured
to autonegotiate.
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 that all connectors are securely
positioned in the required ports. Equipment
might have been accidentally disconnected.
Link/ACT LED is blinking
continuously on all
connected ports and the
network is disabled.
A network loop (redundant path)
has been created. Break the loop by ensuring that only one path exists from any networked device to any other
networked device.
Troubleshooting Suggestions

correctly and that the latest software driver has been installed.

Troubleshooting
20
ProSAFE 24-Port 10/100 Smart Switch with 2 Gigabit Ports FS726Tv2
Configuration
If problems occur after you alter 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 necessary, verify the integrity of the switch by resetting the switch. To reset the switch,
disconnect the AC power from the switch and then reconnect the AC power. If the problem
continues, contact NETGEAR technical support:
•Phone (US & Canada only): 1-888-NETGEAR.
•Phone (Other Countries): Check the list of phone numbers at
http://support.netgear.com/general/contact/default.aspx.
Autonegotiation
The RJ-45 ports negotiate the correct duplex mode and speed if the device at the other end
of the link supports autonegotiation. If the device does not support autonegotiation, the switch
determines only the speed correctly, and the duplex mode defaults to half-duplex.
The Gigabit Ethernet ports negotiate speed, duplex mode, and flow control if the attached
device supports autonegotiation.
