INTRODUCTION
This section describes the features of the DES-2110, as well as giving
some background information about Gigabit Ethernet, Fast 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
4
personnel. The increased speed and extra bandwidth offered by
Gigabit Ethernet are 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 sub-networks. 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 costeffective 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 are not
competing with each other for network transmission capacity, and
therefore decreasing the load on each segment. 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
5
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.
Switch Description
The DES-2110 is equipped with unshielded twisted-pair (UTP) cable
ports providing dedicated 10 or 100 Mbps bandwidth. The Switch has
8 UTP ports and Auto MDI-X/MDI-II convertible ports that can be
used for up-linking to another switch. These ports can be used for
connecting PCs, printers, servers, hubs, routers, switches and other
networking devices. The dual speed ports use standard twisted-pair
cabling and are ideal for segmenting networks into small, connected
sub-networks for superior performance. Each 10/100 port can support
up to 200 Mbps of throughput in full-duplex mode. In addition, the
6
Switch has two gigabit ports are ideal for connecting to a server or
network backbone. 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 Light-Management engine can be configure the Switch's
settings for priority queuing, VLANs, and port monitoring, and port
speed.

UNPACKING AND SETUP
This chapter provides unpacking and setup information for the Switch.
Unpacking
Open the shipping carton of the Switch and carefully unpack its
contents. The carton should contain the following items:
One DES-2110 Switch
Four rubber feet with adhesive backing
One AC power cord
Mounting kit (two brackets and screws)
CD-ROM (This User’s Guide and Utility)
If any item is found missing or damaged, please contact your local
reseller for replacement.
Setup
The setup of the Switch can be performed using the following steps:
Install the Switch on a sturdy, level surface that can support
at least 6.6 lb. (3 kg) of weight. Do not place heavy objects
on the Switch.
The power outlet should be within 1.82 meters (6 feet) of the
device.
Visually inspect the power cord and see that it is fully
secured to the AC power port.
Make sure that there is proper heat dissipation from and
adequate ventilation around the Switch. Leave at least 10 cm
(4 inches) of space at the front and rear of the Switch for
ventilation
Install the Switch in a fairly cool and dry place for the
acceptable temperature and humidity operating ranges.
Install the Switch in a site free from strong electromagnetic
field generators (such as motors), vibration, dust, and direct
exposure to sunlight.
When installing the Switch on a level surface, attach the rubber feet to
the bottom of the device. The rubber feet cushion the Switch, protect
the casing from scratches and prevent it from scratching other
surfaces.
Installing the Switch on a Desktop
When installing the Switch on a desktop or shelf, the rubber feet
included with the Switch should first be attached. Attach these
cushioning feet on the bottom at each corner of the device. Allow
enough ventilation space between the Switch and any other objects in
the vicinity.
