NETGEAR FS308 - Switch User manual

Model FS308 Fast Ethernet Switch Installation Guide
The NETGEAR Model FS308 Fast Ethernet Switch provides you with a low-
cost, high-performance network solution for the home or small office. It is
designed to support power users operating at either 10 megabits per second
(Mbps) or 100 Mbps.
Ethernet switches provide private, dedicated, 10 or 100 Mbps capacity to each
connected PC/server or hub/workgroup segment. 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.
With the Model FS308 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.
The Model FS308 switch has the following key features:
• Eight automatic speed-sensing (autosensing) 10/100 Mbps Ethernet ports to
provide fast information exchange, resource sharing, and client or peer-to-
peer communication using simple Category 5 unshielded twisted pair (UTP)
cable
• IEEE 802.3u standard compliance for interoperation with all 100BASE-TX
Fast Ethernet (100 Mbps) products, 802.3i standard compliance for
interoperation with all 10BASE-T Ethernet products, and 802.3x standard
compliance for flow control
• Automatic address learning function to build the packet forwarding
information table, which contains up to 8,000 MAC addresses so that the
switch can support networks with as many as 8,000 devices
• Easy plug-and-play installation with no software to configure, saving time
and minimizing the potential for configuration errors
• Autosensing full-duplex or half-duplex mode of operation
• Wire-speed filtering and forwarding to provide the “traffic cop” function by
directing traffic to the appropriate port or network segment without slowing
down the traffic
• Internal 100 to 240 V AC power supply, eliminating the need for a bulky
wall transformer
• Normal/Uplink push button to simplify network extension and allow the
switch to connect to a hub using a straight-through cable
• LEDs that provide network traffic status and data transmission speed
— Status indicators on both the front and rear panels
— Eight vista RJ-45 ports

Front Panel
The front panel of the Model FS308 switch contains the following LEDs that
correspond to each network port located on the back of the hub: 100 Mbps link/
activity (100 Link/Act), 10 Mbps link/activity (10 Link/Act), and full-duplex/
collision (FDX/Col). Each vista RJ-45 network port has its own 100 Link/Act
and 10 Link/Act LED as well.
LEDs
The table below describes the activity of the LEDs.
Vista RJ-45 Network Ports with Built-in LEDs
All of the ports on the switch are 10/100 Mbps capable autosensing Ethernet
ports. Each port supports only unshielded twisted pair (UTP) cable using an 8-
pin RJ-45 plug. Each port uses vista RJ-45 connectors that have two LEDs—the
100 Link/Act LED and the 10 Link/Act LED.

Normal/Uplink Push Button
The Normal/Uplink push button on the front panel of the switch allows you to
select uplink (MDI) or normal (MDI-X) wiring for port 8 on the Model FS308
switch. These ports are configured for normal wiring to connect to a PC when
the push button is in the out position. When the push button is pressed in, these
ports are configured for uplink wiring to connect to another switch or to a hub,
using a straight-through twisted pair cable.
Rear Panel
The rear panel of the Model FS308 switch has eight autosensing 10/100 Mbps
Ethernet ports. The rear panel also has full-duplex (FDX) and auto-duplex
(AUTO) toggle switches and a power adapter receptacle for the supplied power
cord.
FDX/AUTO Duplex Toggle Switches
One full-duplex (FDX) and auto-duplex (AUTO) toggle switch is assigned to
each 10/100 Mbps port, enabling the communication mode to be set to either
full-duplex or auto-duplex mode. Full-duplex mode doubles throughput of
point-to-point connections by letting individual ports transmit and receive
concurrently when the connecting device also supports full-duplex mode.
Setting the toggle switch to AUTO on the 10/100 Mbps port enables the port to
determine duplex mode by coordinating with the remote port. In most cases, the
toggle switch should be set to AUTO. If the remote port is a repeater or hub or
cannot provide the proper signal to indicate its duplex capability, the port
defaults to half-duplex mode.
Set the port to full-duplex mode only if the remote device is full-duplex capable
but cannot provide the proper signal to indicate so.

The Model FS308 switch is designed to provide flexibility in configuring your
network connections. Each switch can be used as a standalone device or can be
used with 10 Mbps or 100 Mbps hubs or other interconnection devices in
various configurations. The configuration examples in this section illustrate the
integration of the switches in various network environments using other
NETGEAR products.
Desktop Switching
The Model FS308 switch is used as a desktop switch to build a small network
that enables users to have 100 Mbps access to a file server. If a full-duplex
adapter card is installed in the server or PC, a 200 Mbps connection is possible
on the port where the server or PC is connected.
Segment Switching and Bridging from 10 Mbps to 100 Mbps
The Model FS308 switch is used as a switch that segments a network into
multiple connected pieces, increasing overall bandwidth and throughput. The
Model FS308 switch can segment networks that are built with the NETGEAR
Model DS108 and Model EN104 hubs and can function as an eight-port bridge
connecting traditional 10BASE-T Ethernet networks to 100BASE-TX Fast
Ethernet networks.

Twisted Pair Cables
For two devices to communicate, the transmitter of each device must be
connected to the receiver of the other device. The crossover function is usually
implemented internally as part of the circuitry in the device. Most ports on
switches and repeaters have media-dependent interfaces with crossover ports.
These ports are referred to as MDI-X or normal ports. Computer and
workstation adapter cards are usually media-dependent interface ports referred
to as MDI or uplink ports.
These two figures illustrate the use of straight-through and crossover twisted
pair cables.
RJ-45 Connector
The RJ-45 connector (shown in the illustration with an RJ-45 plug) is used to
connect workstations, hubs, and switches through unshielded twisted pair cable.
The RJ-45 connector accepts four-pair Category 3 or Category 5 UTP cable.
Only two pairs are used for 10BASE-T wiring.
