INTRODUCTION
This chapter describes the features of the DGS-1224T and 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, flow control, and management objects, but with a tenfold
increase in theoretical throughput 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 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

3
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 creates 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 takes
advantage of the existing investment in hardware, software, and
personnel training.

Switching Technology
Another approach to pushing 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 differentsegments, which don’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.
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, the setup and maintenance required
make routers relatively impractical. Today switches are an ideal
solution to most kinds of local area network congestion problems.

5
VLAN (Virtual Local Area Network)
A VLAN is a group of end-stations that are not constrained by their
physical location and can communicate as if a common broadcast
domain, a LAN. The primary utility of using VLAN is to reduce
latency and need for routers, using faster switching instead. Other
VLAN utility includes:
Security, Security is increased with the reduction of opportunity in
eavesdropping on a broadcast network because data will be switched
to only those confidential users within the VLAN.
Cost Reduction, VLANs can be used to create multiple broadcast
domains, thus eliminating the need of expensive routers.
Port-based (or port-group) VLAN is the common method of
implementing a VLAN, and is the one supplied in the Switch.

UNPACKING AND INSTALLATION
This chapter provides unpacking and installation information for the
Switch.
Unpacking
Open the shipping cartons of the Switch and carefully unpacks its
contents. The carton should contain the following items:
uOne DGS-1224T Web Smart Switch
uOne AC power cord, suitable for your area’s electrical power
connections
uFour rubber feet to be used for shock cushioning
uScrews and two mounting brackets
uCD-Rom with Web Management Utility and Manual
uQuick Installation Guide
If any item is found missing or dama ged, please contact your local
reseller for replacement.
Installation
The site where you install the hub stack may greatly affect its
performance. When installing, consider the following pointers:
Install the Switch in a fairly cool and dry place. See Technical
Specifications 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

8
sunlight.
Leave at least 10cm of space at the front and rear of the hub for
ventilation.
Install the Switch on a sturdy, level surface that can support its weight,
or in an EIA standard-size equipment rack. For information on rack
installation, see the next section,Rack Mounting.
When installing the Switch on a level surface, attach the rubber feet to
the bottom of each device. The rubber feet cushion the hub and
protect the hub case from scratching.
Figure 1. Attach the adhesive rubber pads to the bottom
Rack Mounting
The switch can be mounted in an EIA standard-size, 19-inch rack,
which can be placed in a wiring closet with other equipment. Attach
the mounting brackets at the switch’s front panel (one on each side),
and secure them with the provided screws.

Figure 2. Combine the Switch with the provided screws
Then, use screws provided with the equipment rack to mount each
switch in the rack.
Figure 3. Mount the Switch in the rack
Connecting Network Cable
The Switch supports 1000Mbps Gigabit Ethernet that runs in Auto-
negotiation mode and 10Mbps Ethernet or 100Mbps Fast Ethernet that
runs both in half and full duplex mode and 1000Mbps Gigabit
Ethernet runs in full duplex mode using four pair of Category 5 Cable.
These RJ-45 ports are Auto-MDI type port. The Switch can auto
transform to MDI-II or MDI-X type, so you can just make an easy
connection that without worrying if you are using a standard or
crossover RJ45 cable.

10
AC Power
The Switch used theAC power supply 100-240V AC, 50-60 Hz. The
power switch is located at the rear of the unit adjacent to the AC
power connector and the system fan. The switch’s power supply will
adjust to the local power source automatically and may be turned on
without having any or all LAN segment cables connected.

10/100/1000Mbps and auto MDI/MDIX crossover detection function, this
function gives true “plug and play” capability, just need to plug-in the
network cable to the hub directly and don’t care if the end node is NIC
(Network Interface Card) or switch and hub. These ports can operate in
half-duplex mode for 10/100Mbps and full-duplex mode for
10/100/1000Mbps.
