1 INTRODUCTION

This section describes the features of the Switch, as well as giving some background information
about Fast Ethernet, Gigabit Ethernet, and switching technology.

Fast Ethernet Technology

The growing importance of LANs and the increasing complexity of desktop computing applications
are fueling the need for high performance networks. A number of high-speed LAN technologies are
proposed to provide greater bandwidth and improve client/server response times. Among them, Fast
Ethernet, or 100BASE-T, provides a non-disruptive, smooth evolution from 10BASE-T technology.

100Mbps Fast Ethernet is a standard specified by the IEEE 802.3 LAN committee. It is an extension
of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while
maintaining the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Ethernet
protocol.

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 100Mbps Fast Ethernet and a one hundred-fold
increase over 10Mbps Ethernet. Since it is compatible with all 10Mbps and 100Mbps 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 subnetworks.

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.

Switching Technology

Another key development pushing the limits of Ethernet technology is in the field of switching
technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol
transmitting among connected Ethernet or fast Ethernet LAN segments.

Switching is a cost-effective way of increasing the total network capacity available to users on a local
area network. A switch increases capacity and decreases network loading by making it possible for a
local area network to be divided into different segments which don’t compete with each other for
network transmission capacity, giving a decreased load on each.

The switch acts as a high-speed selective bridge between the individual segments. Traffic that needs
to go from one segment to another (from one port to another) is automatically forwarded by the
switch, without interfering with any other segments (ports). This allows the total network capacity
to be multiplied, while still maintaining the same network cabling and adapter cards.

For Fast Ethernet or Gigabit Ethernet networks, a switch is an effective way of eliminating
problems of chaining hubs beyond the “two-repeater limit.” A switch can be used to split parts of the
network into different collision domains, for example, 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
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’s switches are an ideal solution to most kinds of local area network
congestion problems.

DES-1218R/DES-1226R 10/100/1000 Mbps Switch

General Description of Switch

The Switch is equipped with unshielded twisted-pair (UTP) cable ports providing dedicated 10 or 100
Mbps bandwidth. The DES-1218R has 16 UTP ports and the DES-1226R has 24 UTP ports. Each
model includes 16 or 24 MDI-X/MDI-II convertible ports that can be used for uplinking to another
switch. These ports can be used for connecting PCs, servers, and hubs. The dual speed ports use
standard twisted-pair cabling and are ideal for segmenting networks into small, connected
subnetworks. Each port can support up to 200 Mbps of throughput in full-duplex mode.

In addition, the Switch can be fitted with either an optional 2-port Gigabit Ethernet module or a 1­or 2-port 100BASE module. The Gigabit ports are ideal for a high-bandwidth link to a server or
network backbone.

The Gigabit Ethernet modules that can be installed include: DES-132G 2-port 1000BASE-SX (SC
type connector), DES-132GL 2-port 1000BASE-LX, DES-132GB 2-port GBIC, and DES-132T 2-port
1000BASE-T modules.

The 100BASE modules that can be installed include: DES-131FL 1-port 100BASE-FX (15Km), DES­132FL 2-port 100BASE-FX (15Km), DES-131F 1-port 100BASE-FX (2Km), and DES-132F 2-port
100BASE-FX (2Km).

This stand-alone Switch enables the network to use some of the most demanding multimedia and
imaging applications concurrently with other user applications without creating bottlenecks. The
built-in console interface can be used to configure the Switch’s settings for priority queuing, VLANs,
and port trunk groups, port monitoring, and port speed.
