Gigabit 5-Port Workgroup Switch
Chapter 1: Introduction
The Gigabit 5-Port Workgroup Switch provides non-blocking, wire speed
switching for your 10, 100, and 1000 megabit network clients. Drop this switch
in place of your current workgroup hub or switch, and you can upgrade your
high-requirement workstations to full Gigabit speeds as necessary, while con-
tinuing to service other clients at their current speeds. Or build your network
from the ground up, with appropriate link speeds for each user's requirements.
Apply this switching power to your current hub-based Ethernet network, and
your data traffic efficiency will improve several times over. Connect your
Gigabit-equipped workstations to the Switch's 10/100/1000 ports for full-
duplex, dedicated bandwidth of up to 2000Mbps! It's perfect for graphics, mul-
timedia, and other applications that have to move large files across the network
quickly.
With the Gigabit 5-Port Workgroup Switch, you can connect your existing
10/100 Ethernet network to your Gigabit server backbone without any addi-
tional equipment. All ports are auto-negotiating, and have automatic
MDI/MDI-X crossover detection, so you don't have to worry about the cable
type. Address learning and aging is supported, as well as 802.3x flow control
with head-of-line blocking prevention to keep your high-speed clients from
bogging down in lower-speed traffic.
The Gigabit 5-Port Workgroup Switch from Linksys is the perfect solution for
your desktop Gigabit and 10/100 networking needs.

Speed Green. The Speed LED blinks when that port is transmitting at 1000
mbps. If the LED is not lit, the port is transmitting at 10 or 100
mbps.
FDX Amber. If the FDX (Full Duplex/Collision) LED is lit up continu-
ously, the connection made through the corresponding port is run-
ning in Full Duplex mode. If the LED is blinking, the port is expe-
riencing data collisions. Infrequent collisions are normal. If this
LED is blinking often, there may be a problem with your connec-
tion.
Chapter 2: Getting to Know the
Gigabit 5-Port Workgroup Switch
Connections for power and to your network are made through the ports on the
Switch’s Back Panel, shown in Figure 2-1.
Network Ports These LAN (Local Area Network) ports connect network
devices, such as PCs, print servers, and network attached
storage at 10/100/1000Mbps. Or, they can be used to expand
your network by connecting to a 1000Mbps hub or switch.
When connecting to a PC equipped with an Instant Gigabit
Network Adapter, just plug one end of a Category 5e
Ethernet network cable into the RJ-45 port on the Adapter
and the other end into one of the ports on the Gigabit Switch.
Power The Power port is where you will connect the included
power cord.
The LEDs on the Switch’s front panel, shown in Figure 2-2, display network
activity.
Power Green. The Power LED lights up when the Switch is powered
on.
Link/Act Green. The Link/Act LED blinks when data is being sent or
received through the port. When the LED is off, there is no
data being transferred through the port.

Here are some of the ways the new Switch can help you optimize your network
speed.
• Speed up Nodes from Your 10BaseT Network
In a 10BaseT network, connect your hubs, file servers, and key users, such as
network administrators, directly to your Switch to channel dedicated bandwidth
in full-duplex mode (if operating in full-duplex) to each station. The Switch
will have dedicated communication with all its connections simultaneously,
whereas a hub will only communicate in half-duplex transfer mode and broad-
casts information to all ports.
• Conserving Bandwidth with 10Mbps, 100Mbps and 1000Mbps Segments
10BaseT and 100BaseTX hardware are not readily compatible, but the Switch
can designate network segments of different speeds. This allows you to run one
100Mbps segment to serve users without a need for considerable speed, and a
faster 1000Mbps segment devoted to users who depend heavily on graphics,
multimedia, database, or other speed-intensive applications. With switched
segmentation, your 1000Mbps users will not be slowed down by the users on
the 10/100Mbps segment.
• Run 10/100Mbps Peripherals in a 1000Mbps Network
Most of the network peripherals in place today run at 10/100Mbps, since
100BaseTX has been the standard network speed to date. These peripherals,
designed to operate at 100Mbps, cannot readily communicate with
1000BaseTX equipment. A 10Mbps interface is also required for cable and
DSL connections, which are quickly becoming very popular ways to access the
Internet. The Switch provides your 10BaseT equipment and cable and DSL
lines with a 10Mbps interface while still running your Fast Ethernet devices at
100Mbps or your Gigabit devices at 1000Mbps.
• Strengthen Data Transfers through Signal Regeneration
The Switch functions as a repeater, which regenerates data signals as they pass
through it. This feature acts as a safeguard to deter data loss and ensure that
transmissions arrive at their destination intact. Switches positioned between
hubs can preserve your data’s integrity and eliminate your need to buy and use
repeaters in your Fast Ethernet or Gigabit network.
Tips on Switching Your Network
Chapter 3: Installing the Gigabit 5-
Port Workgroup Switch
Installing the EtherFast®Gigabit Ethernet Switch may involve installing both
an adapter and the Gigabit Ethernet Switch. If you are integrating these items
into an existing network, some additional steps may be necessary involving set-
tings for your existing equipment. Consult your network administrator for
more information about how the Gigabit Ethernet Switch will interface with
your existing network components.
The Switch’s back panel has five RJ-45 ports. Each 10/100/1000 port automat-
ically detects the speed and duplex of the attached cabling to a network card,
switch, hub, etc. The ports operate in either 1000Mbps, 100Mbps, or 10Mbps.
Each 10/100/1000 port on your Switch can connect to workstations, file
servers, hubs, routers or other switches. Connections to the switch require
Category 5 Ethernet network cabling (Category 5e for Gigabit connections.
To connect a computer directly to the Switch, plug one end of a standard net-
work cable into the switch, and then plug the other end of the cable into the
computer’s network adapter.
Plug in the Gigabit Ethernet Switch’s power cable. The Power LED will light
up. As devices make connections to the Switch’s ports, each port’s correspon-
ding FDX or ACT LED will light up. The remaining LEDs will also light up
according to how your connection is made, e.g. full or half duplex, 10Mbps,
100Mbps, or 1000Mbps.
If the Switch experiences excessive data collisions, verify that your network
cabling is securely crimped and installed properly.

Boot - To cause the computer to start executing instructions. Personal computers
contain built-in instructions in a ROM chip that are automatically executed on
startup. These instructions search for the operating system, load it and pass con-
trol to it.
CAT 5 - ANSI/EIA (American National Standards Institute/Electronic Industries
Association) Standard 568 is one of several standards that specify "categories"
(the singular is commonly referred to as "CAT") of twisted pair cabling systems
(wires, junctions, and connectors) in terms of the data rates that they can sustain.
CAT 5 cable has a maximum throughput of 100 Mbps and is usually utilized for
100BaseTX networks.
CAT 5e - The additional cabling performance parameters of return loss and far-
end crosstalk (FEXT) specified for 1000BASE-T and not specified for 10BASE-
T and 100BASE-TX are related to differences in the signaling implementation.
10BASE-T and 100BASE-TX signaling is unidirectional-signals are transmitted
in one direction on a single wire pair. In contrast, Gigabit Ethernet is bi-direc-
tional-signals are transmitted simultaneously in both directions on the same wire
pair; that is, both the transmit and receive pair occupy the same wire pair.
Database - A database is a collection of data that is organized so that its contents
can easily be accessed, managed, and updated.
Data Packet - One frame in a packet-switched message. Most data communica-
tions is based on dividing the transmitted message into packets. For example, an
Ethernet packet can be from 64 to 1518 bytes in length.
DSL (Digital Subscriber Line) - A technology that dramatically increases the dig-
ital capacity of ordinary telephone lines into the home or office and, by employ-
ing unused bandwidth, still allows for normal phone usage. DSL provides
"always-on" operation, eliminating the need to dial in to the service.
Ethernet - IEEE standard network protocol that specifies how data is placed on
and retrieved from a common transmission medium. Has a transfer rate of 10
Mbps. Forms the underlying transport vehicle used by several upper-level proto-
cols, including TCP/IP and XNS.
Fast Ethernet - A 100 Mbps technology based on the 10Base-T Ethernet
CSMA/CD network access method.
Full Duplex - The ability of a device or line to transmit data simultaneously in
both directions.
Appendix A: Glossary
10BaseT - An Ethernet standard that uses twisted wire pairs.
100BaseTX - IEEE physical layer specification for 100 Mbps over two pairs of
Category 5 UTP or STP wire.
1000BASE-T - provides half-duplex and full-duplex 1000Mb/s Ethernet service
over Category 5 links as defined by ANSI/TIA/EIA-568-A. Topology rules for
1000BASE-T are the same as those used for 100BASE-T. Category 5 link lengths
are limited to 100 meters by the ANSI/TIA/EIA-568-A cabling standard.
Adapter - Printed circuit board that plugs into a PC to add to capabilities or con-
nectivity to a PC. In a networked environment, a network interface card is the typ-
ical adapter that allows the PC or server to connect to the intranet and/or Internet.
Architecture - The total design and implementation of the network. It includes
the network's topology, transmission technologies and communications proto-
cols, management and security systems, and any other attributes that give a net-
work a particular set of capabilities and functionalities.
Auto-MDI/MDIX - On a network hub or switch, an auto-MDI/MDIX port auto-
matically senses if it needs to act as a MDI or MDIX port. The auto-MDI/MDIX
capability eliminates the need for crossover cables.
Auto-negotiate - To automatically determine the correct settings. The term is
often used with communications and networking. For example, Ethernet 10/100
cards, hubs and switches can determine the highest speed of the node they are
connected to and adjust their transmission rate accordingly.
Backbone - The part of a network that connects most of the systems and net-
works together and handles the most data.
Bandwidth - The transmission capacity of a given facility, in terms of how much
data the facility can transmit in a fixed amount of time; expressed in bits per sec-
ond (bps).
Bit - A binary digit. The value - 0 or 1-used in the binary numbering system.
Also, the smallest form of data.

Network - A system that transmits any combination of voice, video and/or data
between users.
Node - A network junction or connection point, typically a computer or work sta-
tion.
Packet - A unit of data routed between an origin and a destination in a network.
Port - A pathway into and out of the computer or a network device such as a
switch or router. For example, the serial and parallel ports on a personal comput-
er are external sockets for plugging in communications lines, modems and print-
ers.
RJ-45 (Registered Jack-45) - A connector similar to a telephone connector that
holds up to eight wires, used for connecting Ethernet devices.
Router - Protocol-dependent device that connects subnetworks together. Routers
are useful in breaking down a very large network into smaller subnetworks; they
introduce longer delays and typically have much lower throughput rates than
bridges.
Server - Any computer whose function in a network is to provide user access to
files, printing, communications, and other services.
Software - Instructions for the computer. A series of instructions that performs a
particular task is called a "program." The two major categories of software are
"system software" and "application software." System software is made up of
control programs such as the operating system and database management system
(DBMS). Application software is any program that processes data for the user.
A common misconception is that software is data. It is not. Software tells the
hardware how to process the data.
Storage - The semi-permanent or permanent holding place for digital data.
STP - 1. (Shielded Twisted Pair) Telephone wire that is wrapped in a metal sheath
to eliminate external interference. 2. (Spanning Tree Protocol) A technology that
checks your network for any loops. A loop can often occur in complicated or
back-up linked network systems. Spanning-tree detects and directs data along the
shortest path, maximizing the performance and efficiency of the network.
Half Duplex - Data transmission that can occur in two directions over a single
line, but only one direction at a time.
Hardware - Hardware is the physical aspect of computers, telecommunications,
and other information technology devices. The term arose as a way to distinguish
the "box" and the electronic circuitry and components of a computer from the
program you put in it to make it do things. The program came to be known as the
software.
Hub - The device that serves as the central location for attaching wires from
workstations. Can be passive, where there is no amplification of the signals; or
active, where the hubs are used like repeaters to provide an extension of the cable
that connects to a workstation.
IEEE (The Institute of Electrical and Electronics Engineers) - The IEEE
describes itself as "the world's largest technical professional society, promoting
the development and application of electrotechnology and allied sciences for the
benefit of humanity, the advancement of the profession, and the well-being of our
members."
The IEEE fosters the development of standards that often become national and
international standards. The organization publishes a number of journals, has
many local chapters, and several large societies in special areas, such as the IEEE
Computer Society.
LAN (Local Area Network) - A group of computers and associated devices that
share a common communications line and typically share the resources of a sin-
gle processor or server within a small geographic area (for example, within an
office building).
Mbps (Megabits per second) - One million bits per second; unit of measurement
for data transmission.
MDI (Medium Dependent Interface) - On a network hub or switch, a MDI port,
also known as an uplink port, connects to another hub or switch using a straight-
through cable. To connect a MDI port to a computer, use a crossover cable.
MDIX (Medium Dependent Interface Crossed) - On a network hub or switch, a
MDIX port connects to a computer using a straight-through cable. To connect a
MDIX port to another hub or switch, use a crossover cable.

Switch - 1. A data switch connects computing devices to host computers, allow-
ing a large number of devices to share a limited number of ports. 2. A device for
making, breaking, or changing the connections in an electrical circuit.
TCP (Transmission Control Protocol) - A method (protocol) used along with the
IP (Internet Protocol) to send data in the form of message units (datagram)
between network devices. While IP takes care of handling the actual delivery of
the data (routing), TCP takes care of keeping track of the individual units of data
(called packets) that a message is divided into for efficient delivery over the net-
work. TCP is known as a "connection oriented" protocol due to requiring the
receiver of a packet to return an acknowledgment of receipt to the sender of the
packet resulting in transmission control.
TCP/IP (Transmission Control Protocol/Internet Protocol) - The basic commu-
nication language or set of protocols for communications over a network (devel-
oped specifically for the Internet). TCP/IP defines a suite or group of protocols
and not only TCP and IP.
Throughput - The amount of data moved successfully from one place to anoth-
er in a given time period.
Topology - A network's topology is a logical characterization of how the devices
on the network are connected and the distances between them. The most common
network devices include hubs, switches, routers, and gateways. Most large net-
works contain several levels of interconnection, the most important of which
include edge connections, backbone connections, and wide-area connections.
Upgrade - To replace existing software or firmware with a newer version.
UTP - Unshielded twisted pair is the most common kind of copper telephone
wiring. Twisted pair is the ordinary copper wire that connects home and many
business computers to the telephone company. To reduce crosstalk or electro-
magnetic induction between pairs of wires, two insulated copper wires are twist-
ed around each other. Each signal on twisted pair requires both wires. Since some
telephone sets or desktop locations require multiple connections, twisted pair is
sometimes installed in two or more pairs, all within a single cable.
Workgroup - Two or more individuals that share files and databases.
