Introduction
Congratulations on your purchase of the NETGEAR Model FS518 Fast Ethernet Switch. This
switch provides you with a low-cost, high-performance network solution and is designed to
support power workgroups operating at either 10 megabits per second (Mbps) or 100 Mbps.
T o relie ve server and backbone bottlenecks, the Model FS518 switch also has tw o Gigabit Ethernet
fiber uplink ports.
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 a vailable 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 se gment.
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.
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.
Introduction 1-1
Installation Guide for the Model FS518 Fast Ethernet Switch
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.
When all network ports are operating at 100 Mbps and sending traffic to the server, the server
needs a faster transmission speed to avoid bottlenecks. The 1000 Mbps (Gigabit) ports add the
necessary increase in throughput.
Types of Ethernet Switches
Ethernet switches can be classified in different ways—as desktop switches or as segment switches.
A
desktop switch
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
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. Gig abit (1000 Mbps) switch ports are used to
connect to shared network resources and network backbones at higher speed.
segment switch
is designed to support one or a few PCs per port. It is generally used when the
, in contrast, is designed to support an entire workgroup on each port,

Installation Guide for the Model FS518 Fast Ethernet Switch
Model FS518 Switch Overview
The NETGEAR Model FS518 Fast Ethernet Switch with Gigabit uplinks is an autosensing 10/
100 Mbps switch with two Gigabit uplink interfaces. This high-performance 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 FS518 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.
The Model FS518 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
FS518 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 FS518 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 FS518 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 FS518 switch can be used to join these
200-meter segments to enable them to function as a single logical network. With one Model FS518
switch, the reach extends to 400 meters.
The Gigabit Ethernet uplink ports on the Model FS518 switch can be used to connect to the
network backbone and shared network resources such as servers at 1000 Mbps. The full-duplex
1000BASE-SX ports allow users to connect at high speed to a wiring closet or serv er located from
2 to 525 meters away.
All 10/100 ports can autonegotiate the duplex mode with the connected device. If ne gotiation fails,
the ports default to half-duplex mode. Gigabit fiber ports will advertise their full-duple x operation
and negotiate flow control with the connected device. If negotiation fails, the ports will default to
full-duplex mode and no flow control.
Because the Model FS518 switch is an ISO media access control (MAC) layer de vice, 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.
