Planning Your Network
Overview
Building a Gigabit network involves more topology rules in addition to the
10BaseT/100BaseT network rules. These rules specify distance limitations
and cabling specifications. Data loss, collisions, and other network problems
causing down time are likely to occur if the rules below are not followed.
• Use UTP Category 5 (or better) Ethernet cabling with four pairs of wires
and RJ-45 tips for all Fast Ethernet connections. Gigabit connections
should use Category 5e (or better).
Power
Amber. The Power LED lights up when the Switch is pow-
ered on.
• Use the chart below to position your switches, hubs and workstations.
Link/Act
Green. The Link/Act LED serves two purposes. If the LED
is continuously lit up, the Switch is successfully connected to
a device through the corresponding port (1 through 8). If the
LED is flickering, the GigaSwitch is actively sending or
receiving data over that port.

*Hub refers to any type of 100Mbps hub, including regular hubs and stackable hubs. A
10Mbps hub connected to another 10Mbps hub can span up to 100 meters (328 feet).
FD/Col
Green. The FD/Col LED also serves two purposes. If this
LED is lit up continuously, the connection made through the
corresponding port is running in Full Duplex mode. If the
LED flickers, the connection is experiencing collisions.
Infrequent collisions are normal. If this LED flickers too
often, there may be a problem with your network.
• No more than two hubs should be uplinked in a row in a Fast Ethernet net-
work. A set of stacked hubs, which must be stacked with a stacking cable,
counts as one hub or node on the network.
• In Fast Ethernet networks, your 10/100 Switch acts as a repeater, regener-
ating data signals before passing them on to the next device. Passive hubs
do not function as repeaters.

Amber. The 1000 LED lights up when the Gigaswitch port is
operating at 1000Mbps. If the LED is flickering, data is

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.
Installing the EtherFast®
10/100/1000 8+ 1 Workgroup
GigaSwitch onto Your Network
Overview
Scalability allows you to budget for your networking needs over time.
Now networks can run fast and slow segments at the same time for different
users and departments.
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.
Installing your EtherFast® 10/100/1000 8+1 Workgroup 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
involving settings for your existing equipment. Consult your Network
Administrator for more information about how the GigaSwitch will interface
with your existing network components.
In addition to full-duplex transfer, your Switch surges your network with
dedicated bandwidth to each node. For instance, if you connect five com-
puters to your EtherFast 10/100/1000 8+1 Workgroup GigaSwitch, then each
computer will get a dedicated bandwidth of 100Mbps at full duplex transfer.
If you run 5 computers from a 100Mbps hub, then each computer will only
share a part of the 100Mbps bandwidth.
Installing The Workgroup Gigaswitch
Connecting Computers To Your Switch
Your Switch’s rear panel has eight standard RJ-45 ports, plus a Gigabit port.
Each 10/100 port automatically 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 200Mbps, 100Mbps, 20Mbps or
10Mbps. The Gigabit port operates at 1000Mbps or 2000 Mbps.
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.
Each 10/100 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 with RJ-45 tips, not to exceed
100 meters (328 feet) in length.
Gigabit Ethernet is ideal for deployment as a backbone interconnect between
10/100BASE-T switches, 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.
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.

Tips on Switching Your Network
Connecting Your Hardware Together and Booting Up
Plug in the GigaSwitch's AC power adapter. The Power LED will light up. As
devices make connections to the Switch’s ports, each port's corresponding
Link/Act LED will light up. The remaining LEDs will also light up accord-
ing to how your connection is made, e.g. full or half duplex, 10Mbps or
100Mbps.
Here are some of the ways your new EtherFast® 10/100/1000 8+1 Workgroup
GigaSwitch 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 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.
If the Switch experiences excessive data collisions, verify that your network
cabling is securely crimped and installed properly.
• Conserving Bandwidth with 10Mbps & 100Mbps Segments
10BaseT and 100BaseTX hardware are not readily compatible, but your
10/100 Switch can designate network segments of different speeds. This
allows you to run one 10Mbps segment to serve users without a need for con-
siderable speed, and a faster 100Mbps segment devoted to users who depend
heavily on graphics, multimedia, database, or other speed-intensive applica-
tions. With switched segmentation, your 100Mbps users will not be slowed
down by the users on the 10Mbps segment.
• Run 10Mbps Peripherals in Your Fast Ethernet Network
Most of the network peripherals in place today run at 10Mbps, since 10BaseT
has been the standard network speed to date. These peripherals, designed to
operate at 10Mbps, cannot readily communicate with 100BaseTX 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
Switch provides your 10BaseT equipment and cable and DSL lines with a
10Mbps interface while still running your Fast Ethernet devices at 100Mbps.
• 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 data’s integrity and eliminate your need to
buy and use repeaters in your Fast Ethernet network.

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 5 links as defined by ANSI/TIA/EIA-568-A.
Topology rules for 1000BASE-T are the same as those used for 100BASE-TX.
Category 5 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).
FTP (File Transfer Protocol) - A protocol used to transfer files over a TCP/IP net-
work (Internet, UNIX, etc.). For example, after developing the HTML pages for a
Web site on a local machine, they are typically uploaded to the Web server using
FTP.
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.
FTP includes functions to log onto the network, list directories and copy files. It
can also convert between theASCII and EBCDIC character codes. FTP operations
can be performed by typing commands at a command prompt or via an FTP util-
ity running under a graphical interface such as Windows. FTP transfers can also
be initiated from within a Web browser by entering the URL preceded with ftp://.

Unlike e-mail programs in which graphics and program files have to be
"attached," FTP is designed to handle binary files directly and does not add the
overhead of encoding and decoding the data.
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
Full Duplex - The ability of a device or line to transmit data simultaneously in
between users.
both directions.
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.
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.
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.
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.
