1 Introduction
The Switch is equipped with 24 10/100BASE-TX Fast Ethernet ports and 4 combo
10/100/1000BASE-T/SFP (mini-GBIC) ports for flexible copper/fiber Gigabit
connection. The Switch is an effective solution for the small and medium size
business connections. This all-in-one solution economically integrates Gigabit
technology to remove server bottlenecks, and speed up access to the network
backbone.
Figure 1-1 Figure of the Switch
1.1 Gigabit Ethernet Technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet
structure, format, and support for CSMA/CD protocol, full duplex, flow control, and
management objects, but with a tenfold increase in theoretical throughput over
100-Mbps Fast Ethernet and a hundredfold increase over10-Mbps Ethernet. Since it
is compatible with all 10-Mbps and 100-Mbps Ethernet environments, Gigabit
Ethernet provides a straightforward upgrade without wasting a company’s existing
investment in hardware, software, and trained personnel.
The increased speed and extra bandwidth offered by Gigabit Ethernet is essential to
coping with the network bottlenecks that frequently develop as computers and their
busses get faster and more users use applications that generate more traffic.
Upgrading key components, such as your backbone and servers to Gigabit Ethernet
can greatly improve network response times as well as significantly speed up the
traffic between your subnets. Gigabit Ethernet enables fast optical fiber connections
to support video conferencing, complex imaging, and similar data-intensive
applications. Likewise, since data transfers occur 10 times faster than Fast Ethernet,
servers outfitted with Gigabit Ethernet NIC’s are able to perform 10 times the
number of operations in the same amount of time. In addition, the phenomenal
bandwidth delivered by Gigabit Ethernet is the most cost-effective method to take
advantage of today and tomorrow’s rapidly improving switching and routing
internetworking technologies. And with expected advances in the coming years in
silicon technology and digital signal processing that will enable Gigabit Ethernet to
eventually operate over unshielded twisted-pair(UTP) cabling, outfitting your
network with a powerful 1000-Mbpscapable backbone/server connection creates a
flexible foundation for the next generation of network technology products.
1.2 Fast Ethernet Technology
Ethernet, along with its speedier counterpart Fast Ethernet, is the most popular
networking standard in use today. 100Base-T Fast Ethernet is an extension of the
6

The Switch User’s Guide
10Base-T Ethernet standard, designed to raise the data transmission capacity of
10Base-T from 10Mbits/sec to 100Mbits/sec. An important technology incorporated
by 100Base-T is its use of the Carrier Sense Multiple Access with Collision Detection
(CSMA/CD) protocol, which is the same protocol that 10Base-T uses, because of its
ability to work with several different types of cable, including basic twisted-pair wiring.
Both of these features play an important role in network considerations, and they
make 100Base-T an attractive migration path for those networks based on 10Base-T.
Since the 100Mbps Fast Ethernet is compatible with all other 10Mbps Ethernet
environments, it provides a straightforward upgrade and takes advantage of the
existing investment in hardware, software, and personnel training.
1.3 Switching Technology
Switching is a cost-effective way of increasing the total network capacity available to
users on a LAN. If an Ethernet network begins to display symptoms of congestion,
low throughput, slow response times, and high rates of collision, installing a switch to
a network can preserve much or all of the existing network's cabling and workstation
interface card infrastructure while still greatly enhancing the throughput for users. A
switch is a viable solution even if demanding applications, such as multimedia
production and video conferencing, are on the horizon. The most promising
techniques, as well as the best return on investment, could well consist of installing
the right mixture of Ethernet switches.
A switch increases capacity and decreases network loading by dividing a local area
network into different LAN segments. Dividing a LAN into multiple segments is one
of the most common ways of increasing available bandwidth. If segmented correctly,
most network traffic will remain within a single segment, enjoying the full-line speed
bandwidth of that segment. Switches provide full-line speed and dedicated
bandwidth for all connections. This is in contrast to hubs, which use the traditional
shared networking topology, where the connected nodes contend for the same
network bandwidth. When two switching nodes are communicating, they are
connected with a dedicated channel between them, so there is no contention for
network bandwidth with other nodes. As a result, the switch reduces considerably
the likelihood of traffic congestion. For Fast Ethernet networks, a switch is an
effective way of eliminating the problem of chaining hubs beyond the “two-repeater
limit.” A switch can be used to split parts of the network into different collision
domains, making it possible to expand your Fast Ethernet network beyond the
205-meter network diameter limit for 100BASE-TX networks. Switches supporting
both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for
bridging between existing 10Mbps networks and new 100Mbps networks. Switching
LAN technology is a marked improvement over the previous generation of network
hubs and bridges, which were characterized by higher latencies. Routers have also
been used to segment local area networks, but the cost of a router, and the setup
and maintenance required make routers relatively impractical. Today switches are
an ideal solution to most kinds of local area network congestion problems.

3 Connecting the switch
This chapter describes how to connect the Switch to your Fast Ethernet network.
3.1 PC to Switch
Figure 3-1 PC to Switch
A PC can be connected to the Switch via a two-pair Category 3,4, or5 UTP/STP
straight-through cable. For 100Mbps operation Category 5 must be used. The PC
(equipped with a RJ-45 10Mb Ethernet or 100Mb Fast Ethernet NIC) should be
connected to any port of the Switch. The LED indicators for PC connection are
dependent on the LAN card capabilities. If the LED indicators do not light after
making a proper connection, check the PC LAN card, the cable, the Switch
conditions and connections.
3.2 Hub to Switch
A hub (10 or 100BASE-TX) can be connected to the Switch via a two-pair Category
3, 4, or 5 UTP/STP straight cable. For 100Mbps operation a Category 5 cable must
be used. The connection is accomplished from any port of the hub to any port of the
Switch.
3.3 Switch to Switch (other devices)
The Switch can be connected to another switch or other devices (routers, bridges,
etc.) via a two-pair Category 3, 4, 5 UTP/STP straight or crossover cable. A
Category 5 cable must be used for 100Mbps operation. The connection can be done
from any (MDI-X) port of the Switch (Switch A) to any of the 10Mbps, 100Mbps
(MDI-X) port of the other switch (switch B) or other devices.
3.4 Port Speed & Duplex Mode
After plugging the selected cable to a specific port, the system uses auto-negotiation
13

The Switch User’s Guide
to determine the transmission mode for any new twisted-pair connection:
If the attached device does not support auto negotiation or has auto-negotiation
disabled, an auto sensing process is initiated to select the speed and set the duplex
mode to half-duplex.

4.2 Console Management
A local console is a terminal or a workstation running a terminal emulation program
that is connected directly to the switch via the RS-232 console port on the rear of the
switch. Local console management uses the terminal connection to operate the
console program built-in to the Switch a network Administrator can manage, control
and monitor the switch from the console program.
To start using the Console Management program, first connect an EIA-232 serial
cable to a COM port on a PC or notebook computer and to the Console Port on the
rear panel of the Switch. Note: do not use a null modem cable.
