Introduction
Congratulations on your purchase of the NETGEAR™Model FS562 8-Port Fast Ethernet Fiber
Switch or the Model FS566 12-Port Fast Ethernet Fiber Switch. These switches provide you with
a low-cost, high-performance network solution and are designed to support power workgroups
operating at either 10 megabits per second (Mbps) or 100 Mbps.
This guide describes how to install and use the Model FS562 and Model FS566 Fiber Switches.
It includes physical configuration guidelines for connecting multiple 10 or 100 Mbps hubs and for
connecting 10 or 100 Mbps Fast Ethernet stations, PCs, and servers.When discussing features,
functions, or specifications that apply to both switch models, the guide refers to the Model FS562/
FS566 switch.
Benefits of Using Switching Technology
A majority of installed networks today are based on shared network technology. With this
technology, a number of users or groups of users share a total available network bandwidth (or
network capacity) of 10 Mbps, 100 Mbps, or other amounts of network bandwidth. For example,
with a total of 10 users, the average bandwidth available to each user on a 10 Mbps network is
calculated as 10/10 Mbps, which equals 1 Mbps of bandwidth per user. On a 100 Mbps
(Fast Ethernet) network, the average bandwidth available to each of the 10 users is 100/10 Mbps,
which equals 10 Mbps of bandwidth per user.
Ethernet switches significantly increase network throughput by segmenting network traffic.
They check traffic coming in to each port to learn which network device is located on which
segment. Based on this information, switches forward cross-segment traffic only to the appropriate
segment. The traffic will not show up in the other segments because it is filtered out. In this way,
network capacity is fully reserved for traffic destined for that segment only, and other segments
will not be saturated with unnecessary traffic.

Installation Guide for the Model FS562 and Model FS566 Fiber Switches
1-2 Introduction
Ethernet switches provide private, dedicated, 10 Mbps (or 100 Mbps) capacity to each connected
PC/server or hub/workgroup segment, which is significantly higher than in a shared environment.
The higher bandwidth enables the use of applications such as multimedia, imaging, video, or high-
performance client-server functions among users who are spread out over the network.
This improvement is accomplished very easily, with no change to the desktop (the network
interface cards or software and the network wiring). As a result, the performance upgrade and
the applications it enables are obtained very quickly and at a low cost.
Types of Ethernet Switches
Ethernet switches can be classified in different ways—as desktop switches or as segment switches.
Adesktop switch is designed to support one or a few PCs per port. It is generally used when the
individuals need the full 10 Mbps network throughput to support the applications. Often, these
switches support only a single MAC (media access control) address per port, have high-speed
100 Mbps ports to connect to fast servers, and are relatively inexpensive compared to a segment
switch. A segment switch, in contrast, is designed to support an entire workgroup on each port,
with each port having significant memory buffering and supporting thousands of MAC addresses.
Switches can also be classified by speed. As the name suggests, 10 Mbps switches support only
10 Mbps connections. Similarly, 100 Mbps switches support only 100 Mbps connections. Usually,
10/100 Mbps switches have primarily 10 Mbps ports with only one or a few 100 Mbps ports.
Autosensing 10/100 Mbps switches support 10 Mbps or 100 Mbps connections on each port and
are the most versatile and adaptive type of switches.
Model FS562/FS566 Switch Overview
The Model FS562/FS566 Fast Ethernet Fiber Switch is an autosensing 10/100 Mbps switch.
This feature-rich switch is developed primarily to be used as a segment switch, even though it
is priced as a desktop switch.
All of the UTP ports on the Model FS562/FS566 switch can adapt automatically to the speed
of the connected network or the PC, and the ports can operate at either 10 Mbps or 100 Mbps.
In addition, each port can automatically negotiate with the connected device to operate in
full-duplex mode. If the connected device is operating in half-duplex mode only or does not have
the capability to participate in the negotiation process, the port will default to half-duplex mode.
A manual override duplex toggle switch is also provided to force any particular port to operate in
full-duplex mode.

Installation Guide for the Model FS562 and Model FS566 Fiber Switches
Introduction 1-3
The Model FS562/FS566 switch can be used to partition a 10 Mbps or 100 Mbps network to
enhance the capacity of the network to support advanced applications. In addition, the switch
provides a link between traditional 10 Mbps networks and faster 100 Mbps networks. By installing
a Model FS562/FS566 switch, a user can connect any 10 Mbps or 100 Mbps device to the switch
without worrying about the running speed of the device. The Model FS562/FS566 switch provides
a built-in upgrade path; you can remove a 10 Mbps connection and replace the connection with a
100 Mbps connection with little or no change to the rest of the network.
The Model FS562/FS566 switch can be effectively used to join multiple 100 Mbps Fast Ethernet
segments and to extend the reach of the network. Copper-based Fast Ethernet networks have a
network diameter of up to 200 meters. The Model FS562/FS566 switch can be used to join these
200-meter segments to enable them to function as a single logical network. With one Model
FS562/FS566 switch, the reach extends to 400 meters. With two switches, the reach extends to
2 kilometers (km) when both switches are operating at full-duplex. For an illustration of using the
switch to extend a network, refer to Figure 3-3 on page 3-4.
Because the Model FS562/FS566 switch is an ISO media access control (MAC) layer device, the
switch is network protocol independent and compatible with all popular networks such as the
Internet or TCP/IP, NetWare, DECnet, Microsoft®NETBEUI, and LANTASTIC.
Features
The Model FS562/FS566 switch has the following key features:
• Six automatic speed-sensing (autosensing) 10/100 Mbps UTP ports to provide fast information
exchange, resource sharing, and client or peer-to-peer communication using simple Category 5
unshielded twisted pair (UTP) cable
• Two (Model FS562 switch) or six (Model FS566 switch) 100BASE-FX Fast Ethernet fiber
ports
• Automatic address-learning function to build the packet-forwarding information table
The table contains up to 4,000 MAC addresses (that is, the switch can support networks with
as many as 4,000 devices).

Installation Guide for the Model FS562 and Model FS566 Fiber Switches
1-4 Introduction
• Switch-selectable autonegotiating or full-duplex mode of operation for UTP ports
Full-duplex mode doubles throughput of point-to-point connections by letting individual ports
transmit and receive concurrently when the other end also supports full-duplex mode. The
default is half-duplex if the connected device does not support N-way negotiation. The duplex
toggle switch can be set to full-duplex if the connected port is operating at full-duplex mode.
• Switch-selectable full-duplex or half-duplex mode of operation for the fiber ports
• Wire-speed filtering and forwarding to provide “traffic cop” function by directing traffic to
the appropriate route without slowing down the traffic
• Store-and-forward forwarding node to minimize erroneous packets on the network
• Minimum latency of packet transmission (leading edge to leading edge) less than 80 P s
• Easy plug-and-play installation with no software to configure, which saves time and
minimizes the potential for configuration errors
• Normal/Uplink push button to simplify network extension
The switch can be connected to a hub using a simple, straight-through cable.
• Protocol independence and compatibility with all common protocols such as TCP/IP,
NetWare, DECnet, and Microsoft Networks
• Six vista RJ-45 network ports with built-in LEDs to monitor individual port status
• Microprocessor-based design to monitor network utilization, collisions, and link status
• A comprehensive LED indicator panel for monitoring switching condition and individual
port status
• Conformity to the IEEE 802.3u 100BASE-TX and 100BASE-FX standard
• Conformity to the ISO/IEC 8802-3 and ANSI/IEEE 802.3 10BASE-T standards
• 64 kilobyte (KB) input/output buffer for each port
• Rack Mount Kit provided for installing the switch in a standard 19-inch equipment rack

Fast Ethernet Ports
As Figure 2-1 and Figure 2-2 show, the Model FS562 and Model FS566 switches are equipped
with six autosensing 10/100 Mbps Fast Ethernet UTP ports. The network access speed for the
10/100 Mbps ports is automatically sensed and displayed on the front panel by the 10 Mbps or
100 Mbps LEDs.
The 10/100 Mbps ports support only unshielded twisted pair (UTP) cable using an 8-pin RJ-45
plug.
Each of the 10/100 Mbps ports uses vista RJ-45 connectors that have built-in LEDs, as illustrated
in Figure 2-3. The LEDs, as described in Table 2-1 on page 2-6, indicate that the connection to the
port is valid and that the port is operating at either 10 or 100 Mbps.
For further information about the vista RJ-45 connector and the RJ-45 plug, refer to Appendix B,
“Connector Pin Assignments,” and Appendix C, “Cabling Guidelines.”
