NTRODUCTION
This chapter describes the features of the DES-1010G and some background
information about Gigabit Ethernet/Fast 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 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 buses 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 increased 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.
Fast Ethernet Technology
Ethernet, along with its speedier counterpart Fast Ethernet, is the most
popular networking standard in use today. 100BaseT Fast Ethernet is an
3
extension of the 10BaseT Ethernet standard, designed to raise the data
transmission capacity of 10BaseT from 10Mbits/sec to 100Mbits/sec. An
important strategy incorporated by 100BaseT is its use of the Carrier Sense
Multiple Access with Collision Detection (CSMA/CD) protocol - which is
the same protocol that 10BaseT 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 100BaseT an attractive migration path for those networks based on
10BaseT. 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 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 LAN (local area network). A switch increases capacity
and decreases network loading by making it possible for a LAN 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.

Two 10/100/1000Mbps Gigabit Ethernet ports (ports 9 ~ 10).
Eight 10/100Mbps Fast Ethernet ports (ports 1 ~ 8).
Store-and-forward switching scheme capability to support rate
adaptation and protocol conversion.
Full-duplex to allow two communicating stations to transmit and
receive at the same time.
Wire-speed data forwarding rate for each port.
Wire-speed data filtering rate for each port.
6K active MAC address entry table per device with automatic
learning and aging.
256Kbytes packet buffer per device.

NPACKING AND SETUP
Unpacking
Open the shipping carton of the Switch and carefully unpack its contents. The
carton should contain the following items:
One DES-1010G 8-port 10/100Mbps plus 2-port
10/100/1000Mbps Gigabit Ethernet Switch
Four rubber feet with adhesive backing
Screws and two mounting brackets
One AC power cord

Quick Installation Guide
If any item is missing or damaged, please contact your local reseller for
replacement.
Setup
The setup of the Switch can be performed by using the following steps:
The surface must support at least 11 lbs (5 kg).
The power outlet should be within 6 feet (1.82 meters) of the
device.
Visually inspect the power cord and see that it is secured fully to
the AC power outlet on the Switch.
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.
Do not place heavy objects on the Switch.
7
Desktop Installation
When installing the Switch on a desktop or shelf, the rubber feet included
with the device should be attached first, to minimize scratching or scarring of
the surface on which the Switch is placed. Attach these cushioning feet on the
bottom at each corner of the device. Allow enough ventilation space between
the device and the objects around it.

Rack Installation (optional)
The DES-1010G Gigabit Ethernet Switch can be mounted in an EIA
standard-size 19-inch rack, in a wiring closet with other equipment. Attach
the mounting brackets on each side of the Switch’s front panel (as shown in
the illustration below), and secure them with the screws provided.

Then, use the screws provided with the equipment rack to mount the Switch
in the rack.

Connecting Network Cable
The DES-1010G supports two 10/100/1000Mbps Gigabit Ethernet ports and
eight 10/100Mbps Fast Ethernet ports. Port 1 to port 8 supports 10Mbps
Ethernet or 100Mbps Fast Ethernet. Port 9 to port 10 are Gigabit Ethernet
ports; it supports 10Mbps, 100Mbps and 1000Mbps. And these ports run both
half-duplex and full-duplex while it’s running in 10Mbps, 100Mbps or
1000Mbps.
All ports on the DES-1010G are Auto-MDI/MDIX type ports. These ports
can auto transform to MDI-II or MDI-X type, so you can just make an easy
connection without worrying if you are using a standard or crossover cable.
Power On
The DES-1010G Gigabit Ethernet Switch can be used with AC power
sources 100 - 240 VAC, 50 - 60 Hz. 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.

POWER (PWR)
After turning on the power, the Power indicator on the front panel should
light to indicate the Switch is receiving power.
SPEED
The indicator lights amber when the port is connected to 1000Mbps
Gigabit Ethernet station, and the indicator lights green when the port is
connected to 100Mbps Fast Ethernet station. Otherwise, this indicator
remains off when the port is connected to a 10Mbps Ethernet station.
LINK/ACT
This indicator lights green when a port is connected to a station
successfully and has a good link. A blinking green indicator means that a
port is transmitting or receiving data on the network.
FDX/COL
This LED indicator lights green when a respective port is in full duplex
(FDX) mode. Otherwise, it is blinking green when collisions are
occurring on the respective port.
