ABOUT THIS GUIDE
Thank you and congratulations on your purchase of the DES-1228P
24-Port 10/100Mbps Fast Ethernet + 4 10/100/1000Base-T Ports and
2 Combo SFP PoE Web-Smart Switch. This device integrates
1000Mbps Gigabit Ethernet, 100Mbps Fast Ethernet and 10Mbps
Ethernet network capabilities in a highly flexible package. Since Ports
1~24 of this Switch are Power over Ethernet (PoE) ports, it will
automatically detect the presence of IEEE 802.3af compliant devices
and will provide power through these PoE ports. The Switch provides
up to 15.4Watts per port and can be connected to WLAN access
points, IP phones, video cameras, and other PD devices. The Switch
will automatically detect the network appliance's requirements, and
the Switch will supply the required power current to each appliance.
Purpose
This guide will show you how to install and use the configuration
functions of the DES-1228P Web-Smart Switch step-by-step.
Terms/Usage
In this guide, the term “Switch” (first letter capitalized) refers to the
DES-1228P Smart Switch, and “switch” (first letter lower case) refers
to other Ethernet switches. Some technologies refer to terms “switch”,
“bridge” and “switching hubs” interchangeably, and both are
commonly accepted for Ethernet switches.

INTRODUCTION
This chapter will describe the features of the DES-1228P and provide
some background information about Ethernet/Fast Ethernet/Gigabit
Ethernet switching technology.
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, and management objects, but with a tenfold increase in
theoretical throughput of over 100-Mbps Fast Ethernet and a
hundredfold increase over 10-Mbps Ethernet. Since it is compatible
with all 10-Mbps and 100-Mbps Ethernet environments, Gigabit
Ethernet provides a straightforward upgrade without wasting existing
investments in hardware, software, or trained personnel.
The increased speed and extra bandwidth offered by Gigabit Ethernet
is essential to help solving network bottlenecks that frequently
develop as more advanced computer users and newer applications
continue to demand greater network resources. Upgrading key
components, such as backbone connections and servers to Gigabit
Ethernet technology can greatly improve network response times as
well as significantly speed up the traffic between 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-Mbps-
capable backbone/server connection which will create a flexible
foundation for the next generation of network technology products.
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
have been proposed to provide greater bandwidth and improve
client/server response times. Among them, 100BASE-T (Fast
Ethernet) provides a non-disruptive, smooth evolution from the
current 10BASE-T technology. The non-disruptive and smooth
evolution nature, and the dominating potential market base, virtually
guarantees cost-effective and high performance Fast Ethernet
solutions.
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 CSMA/CD Ethernet protocol. Since the 100Mbps
Fast Ethernet is compatible with all other 10Mbps Ethernet
environments, it provides a straightforward upgrade and utilizes
existing investments in hardware, software, and personnel training.

Switching Technology
Another approach to push beyond the limits of Ethernet technology is
the development 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 dividing a local area
network into different segments, which won’t compete with each other
for network transmission capacity.
The switch acts as a high-speed selective bridge between the
individual segments. The switch, without interfering with any other
segments, automatically forwards traffic that needs to go from one
segment to another. By doing this the total network capacity is
multiplied, while still maintaining the same network cabling and
adapter cards.
Power over Ethernet (PoE)
Power over Ethernet (PoE) integrates power and data onto one single
cabling infrastructure, eliminating the need to have AC power
available at all locations.
Power and Data are integrated onto the same cable. Supporting
category 5/5e up to 100 Meters, PoE will provide power to PoE
compatible devices, such as IP telephones, wireless LAN access
points, and IP security cameras.

PoE is already widely adopted in the market, saving up to 50% of
overall installation costs by eliminating the need to install separate
electrical wiring and power outlets.
