The 5- or 8-Port 10/100/1000 Gigabit 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 neces-
sary, while continuing 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.

With the 5- or 8-Port 10/100/1000 Gigabit Switch, you can connect your exist-
ing 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.

10/100/1000 Gigabit Switch
Overview
The 5- and 8-Port 10/100/1000 Gigabit Switches differ in number of LEDs and
ports. Pictured here is the 5-Port Switch; however, the other Switch is similar
in form.

To connect network devices to the Switch, follow these instructions.
10/100/1000 Gigabit Switch
1. Make sure all the devices you will connect to the Switch are powered off.
Overview
2. Connect a Category 5 Ethernet
network cable to one of the
numbered ports on the Switch.
This chapter will explain how to connect network devices to the Switch. For an
example of a typical network configuration, see the application diagram shown
in Figure 3-1.
Figure 3-2
Note: Use Category 5e Ethernet network cables for your Gigabit con-
nections.
3. Connect the other end to a PC or other network device.
4. Repeat steps 2 and 3 to connect additional devices.
5. Connect the supplied power
adapter to the power port on
the Switch’s side panel.

When you connect your network devices, make sure you don’t exceed the max-
imum cabling distances, which are listed in the following table:

Appendix A: Glossary
10BaseT - An Ethernet standard that uses twisted wire pairs.
Set the Switch on its four rubber feet, or hang the Switch on a wall using its
wall-mount slots.
To use the wall-mount option, follow these instructions:
100BaseTX - IEEE physical layer specification for 100 Mbps over two pairs of
Category 5 UTP or STP wire.
1. The wall-mount slots are two
crisscross slots on the Switch’s
bottom panel, as shown in
Figure 3-4. Attach two screws
to the wall, so that the Switch’s
wall-mount slots line up with
the two screws.
1000Base-T - Provides half-duplex 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 100BaseT. Category 5 link lengths
are limited to 100 meters by the ANSI/TIA/EIA-568-A cabling standard.
Auto MDI/MDI-X - On a network hub or switch, an auto MDI/MDI-X port
automatically senses if it needs to act as a MDI or MDI-X port. The auto-
MDI/MDI-X capability eliminates the need for crossover cables.
2. Maneuver the Switch so the
screws are inserted into the
two slots.
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.
Figure 3-4
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.
Congratulations!
The installation of the 10/100/1000 Gigabit Switch is complete.
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.
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
protocols, including TCP/IP and XNS.

Fast Ethernet - A 100 Mbps technology based on the 10Base-T Ethernet
CSMA/CD network access method.
Appendix B: Specifications
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.

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 networks contain several levels of interconnection, the most impor-
tant of which include edge connections, backbone connections, and wide-area
connections.

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.
