Switches Versus Hubs  
Your GigaSwitch boosts your network performance several times over, con-  
serving your time, money and resources. The Switchs 10/100/1000 feature  
gives you a key advantage over other forms of networking by upgrading  
speed-critical network segments to 1000Mbps while allowing existing  
10BaseT and 100BaseTX networks to operate with the Switch. Allowing  
10BaseT and 100BaseTX hardware speeds to run alongside each other elimi-  
nates the need to purchase new hardware, rewire and reconfigure an entire  
site all at once. This scalability factor ensures that Fast Ethernet will not fall  
obsolete to upgrades in speed standards and maintains use of all your old  
equipment until you decide to buy speedier replacements.  
The LED Indicators  
Power  
Green. The Power LED lights up when the Switch is pow-  
ered on.  
1000  
Green. The 1000 LED lights up when the port is operating at  
1000Mbps. If the LED is off, the port is operating at either  
100Mbps, 10Mbps, or it is not active.  
Switches also feature full-duplex data transfer, meaning that all computers  
on the switch can “talk” to the switch at the same time. Plus, switches can  
send and receive data simultaneously to all connections, whereas a hub can-  
not. A hub simply works with one computer at a time and only sends or  
receives data, since it cannot handle two way communication.  
100  
Green. The 100 LED lights up when the port is operating at  
100Mbps. If this LED is off, the port is operating at either  
1000Mbps, 10Mbps, or it is not active.  
In addition to full-duplex transfer, your Switch surges your network with  
dedicated bandwidth to each node. For instance, if you connect 8 comput-  
ers to your EtherFast 10/100/1000 8-Port GigaSwitch , then each computer  
will get a dedicated bandwidth of 2000Mbps at full duplex transfer. If you  
run 8 computers from a 100Mbps hub, then each computer will only share a  
part of the 100Mbps bandwidth.  
10  
Amber. The 10 LED lights up when the port is operating at  
10Mbps. If this LED is off, the port is operating at either  
1000Mbpd, 100Mbps, or it is not active.  
TX  
Green. The TX (Transmit) LED flickers when data is being  
transmitted through the port. When the LED is off, there is  
no data being transferred through the port.  
A network without a switch is called a shared network because every node  
on the network competes for a fraction of the total bandwidth. In a shared  
network, data packets are randomly broadcasted to all stations until they  
discover their intended destination. Consequently, considerable time and  
bandwidth is wasted on data packets swimming along network lines before  
they find their correct address. A switch, on the other hand, looks at the  
address for each data packet and delivers it directly to the correct destination.  
RX  
Amber. The RX (Receive) LED flickers when data is being  
received through the port. When the LED is off, there is no  
data being transferred through the port.  
FD/COL  
Green. If the FD/COL (Full Duplex/Collision) LED is lit up  
continuously, the connection made through the correspon-  
ding port is running in Full Duplex mode. If the LED is flick-  
ering, the port is experiencing data collisions. Infrequent  
collisions are normal. If this LED is flickering too often,  
there may be a problem with your connection.  
Gigabit Ethernet is ideal for deployment as a backbone interconnect, and as a  
connection to high-performance servers. With the addition of Gigabit  
Ethernet, Ethernet delivers scalable solution (10/100/1000 Mbps) for the  
LAN from the desktop to the workgroup, and the backbone.

Tips on Switching Your Network  
Installing the EtherFast®  
Here are some of the ways your new EtherFast® 10/100/1000 8-Port  
GigaSwitch can help you optimize your network speed.  
10/100/1000 8-Port GigaSwitch  
• Speed up Nodes From Your 10BaseT Network  
Overview  
In a 10BaseT network, connect your hubs, file servers, and key users, such as  
network administrators, directly to your Switch to channel dedicated band-  
width in full-duplex mode (if operating in full-duplex) to each station. The  
Switch will have dedicated communication with all its connections simultane-  
ously, whereas a hub will only communicate in half-duplex transfer mode and  
broadcasts information to all ports.  
Installing your EtherFast® 10/100/1000 8-Port GigaSwitch may involve  
installing both an adapter and the GigaSwitch. If you are integrating these  
items into an existing nework, some additional steps may be necessary involv-  
ing settings for your existing equipment. Consult your Network Administrator  
for more information about how the GigaSwitch will interface with your exist-  
ing network components.  
Installing 10/100/1000 The 8-Port Gigaswitch  
• Conserving Bandwidth with 10Mbps, 100Mbps and 1000Mbps Segments  
Connecting Computers To Your Switch  
10BaseT and 100BaseTX hardware are not readily compatible, but your  
10/100/1000 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.  
Your Switchs front panel has eight RJ-45 ports. Each 10/100/1000 port auto-  
matically detects the speed and duplex of the attached cabling to a network  
card, switch, hub, etc. The ports operate in either full or half duplex, which  
lets you run at speeds of 2000Mbps, 1000Mbps, 200Mbps, 100Mbps, or  
10Mbps.  
Each 10/100/1000 port on your Switch can connect to workstations, file  
servers, hubs, repeaters, bridges, routers or other switches. Connections to the  
switch require UTP Category 5 network cabling (UTP Category 5e for  
Gigabit connections—UTP Category 3 can be used with 10Mbps connec-  
tions) with RJ-45 tips, not to exceed 100 meters (328 feet) in length.  
• Run 10/100Mbps Peripherals in 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. Your 10/100/1000 Switch provides your 10BaseT equipment and  
cable and DSL lines with a 10Mbps interface while still running your Fast  
Ethernet devices at 100Mbps or 1000Mbps.  
To connect a computer directly to the switch, plug one end of a standard net-  
work cable into the switch, then plug the other end of the cable into the com-  
puter's network adapter.  
Connecting Your Hardware Together and Booting Up  
Plug in the GigaSwitch's power cable. The Power LED will light up. As  
devices make connections to the Switchs ports, each port's corresponding TX  
or RX 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.  
• Strengthen Data Transfers Through Signal Regeneration  
Your 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 datas integrity and eliminate your need to  
buy and use repeaters in your Fast Ethernet network.  
If the Switch experiences excessive data collisions, verify that your network  
cabling is securely crimped and installed properly.

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.  
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.  
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 imple-  
mentation. 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-directional-signals are transmitted simultaneously in both direc-  
tions on the same wire pair; that is, both the transmit and receive pair occupy  
the same wire pair .  
1000BASE-T - provides half-duplex (CSMA/CD) and full-duplex 1000Mbps  
Ethernet service over Category 5e links as defined by ANSI/TIA/EIA-568-A.  
Topology rules for 1000BASE-T are the same as those used for 100BASE-TX.  
Category 5e link lengths are limited to 100 meters by the ANSI/TIA/EIA-568-  
A cabling standard. Only one CSMA/CD repeater will be allowed in a collision  
domain.  
Data Packet - One frame in a packet-switched message. Most data communi-  
cations is based on dividing the transmitted message into packets. For example,  
an Ethernet packet can be from 64 to 1518 bytes in length.  
Adapter - Printed circuit board that plugs into a PC to add to capabilities or  
connectivity to a PC. In a networked environment, a network interface card  
(NIC) is the typical adapter that allows the PC or server to connect to the  
intranet and/or Internet.  
Dynamic Routing - The ability for a router to forward data via a different route  
based on the current conditions of the communications circuits. For example, it  
can adjust for overloaded traffic or failing lines and is much more flexible than  
static routing, which uses a fixed forwarding path.  
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.  
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.  
Backbone - The part of a network that connects most of the systems and net-  
works together and handles the most data.  
Fast Ethernet - A 100 Mbps technology based on the 10BASE-T Ethernet  
CSMA/CD network access method.  
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 second (bps).  
Full Duplex - The ability of a device or line to transmit data simultaneously in  
both directions.  
CAT 3 - 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 3 cable has a maximum throughput of 16 Mbps and  
is usually utilized for 10BaseT networks.  
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 pro-  
gram you put in it to make it do things. The program came to be known as the soft-  
ware.

EtherFast® 10/100/1000 8-Port GigaSwitch  
Instant Gigabit™ Series  
Hub - The device that serves as the central location for attaching wires from  
workstations. Can be passive, where there is no amplication of the signals; or  
active, where the hubs are used like repeaters to provide an extension of the  
cable that connects to a workstation.  
RJ-45 (Registered Jack-45) - A connector similar to a telephone connector that  
holds up to eight wires, used for connecting Ethernet devices.  
Throughput - The amount of data moved successfully from one place to  
another in a given time period.  
IEEE - The Institute of Electrical and Electronics Engineers. The IEEE  
describes itself as "the world's largest technical professional society -- promot-  
ing 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."  
TX Rate - Transmission Rate.  
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  
twisted 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.  
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 - A local area network (LAN) is a group of computers and associated  
devices that share a common communications line and typically share the  
resources of a single processor or server within a small geographic area (for  
example, within an office building).  
Latency - The time delay between when the first bit of a packet is received and  
the last bit is forwarded.  
MAC Address - The MAC (Media Access Control) address is your computer's  
unique hardware number.  
Mbps (MegaBits Per Second) - One million bits per second; unit of measure-  
ment for data transmission.  
Network - A system that transmits any combination of voice, video and/or data  
between users.  
NIC (Network Interface Card) - A board installed in a computer system, usu-  
ally a PC, to provide network communication capabilities to and from that com-  
puter system. Also called an adapter.  
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 com-  
puter are external sockets for plugging in communications lines, modems and  
printers.
