Introduction

Congratulations on your purchase of the NETGEAR

™

Model FS508 8-port Fast Ethernet Switch.

This switch is part of the NETGEAR 500 Series product family. The 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.

This guide describes how to install and use the switch. 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.

Beneﬁts of Using SwitchingTechnology

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 10/100 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 since 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 FS508 Fast Ethernet Switch

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 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.

desktop 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 one or 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 FS508 Switch Overview

The Model FS508 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 eight ports on the Model FS508 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 at 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.
