INTRODUCTION
This section describes the features of the 10-port 10/100/1000Mbps
Gigabit Ethernet Switch, as well as giving some background
information about Gigabit Ethernet, Fast Ethernet and Switching
technology.
Gigabit Ethernet Technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet, which utilizes
the same packet structure, packet format, and supports CSMA/CD
protocol, full duplex, flow control, and management objects.
Performance wise, the theoretical throughput of the Gigabit Ethernet is
ten times faster than the 100Mbps Fast Ethernet and 100 times faster
than the 10Mbps Ethernet. Since it is compatible with all 10Mbps and
100Mbps Ethernet environments, Gigabit Ethernet provides a
straightforward upgrade without wasting company’s existing
investment in hardware, software, and trained personnel.
The increased speed and extra bandwidth offered by Gigabit Ethernet
are essential to cope with the network bottlenecks that caused by the
traffics generated from faster computers and applications that require
more bandwidth. 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.
Fiber 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

3
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. With the fast growing advanced silicon technology and
digital signal processing, Gigabit Ethernet is now operating over CAT5
unshielded twisted-pair (UTP) cabling, outfitting your network with a
powerful 1000Mbps capable backbone/server connection creates a
flexible foundation for the next generation of network technology
products.
FastEthernet 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-TX (Fast
Ethernet) provides a non-disruptive, smooth evolution from the
10BASE-T technology. The non-disruptive and smooth evolution and
the dominating potential marketbase, virtually guarantee cost effective
and high performance Fast Ethernet solutions in the years to come.
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 most of the 100Mbps Fast
Ethernet products are 10/100Mbps dual-speed, they are compatible
with 10Mbps Ethernet environments, which provides a straightforward

4
upgrade and take 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 FastEthernet LAN segments.
Switching is a cost-effective way of increasing the total network
capacity available to users on a Local Area Network (LAN). 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. It automatically forwards traffic that needs to go
from one segment to another, without interfering with any other
segments. This allows the total network capacity to be 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, the setup, and the maintenance required for the
router, make it relatively impractical. Today’s switches are an ideal
solution to most kinds of LAN congestion problems.

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 10-port 10/100/1000Mbps Gigabit Ethernet Switch
? ?Four rubber feet with adhesive backing
? ?One AC power cord
? ?This User’s Guide
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:
? ?The surface must support at least 5 kg.
? ?The power outlet should be within 1.82 meters (6 feet) of the
device.

7
? ?Visually inspect the power cord and see that it is secured fully
to the AC power connector.
? ?Make sure that there is adequate room for ventilation around
the Switch and do not place heavy object on the Switch.
Desktop or Shelf Installation
When installing the Switch on a desktop or shelf, the rubber feet
included with the device must be first attached. 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 10-port 10/100/1000Mbps Gigabit Ethernet Switch can be mounted
in an EIA standard size, 19-inch rack, which can be placed in a wiring
closet with other equipment. To install, attach the mounting brackets
on the switch’s front panel (one on each side) and secure them with
the screws provided.

Connecting Network Cable
The Gigabit Ethernet Switch 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 and
port 10 are Gigabit Ethernet ports and they support 10Mbps, 100Mbps
and 1000Mbps. All ports support half duplex or full duplex.
All ports are Auto-MDI type port, they auto-senses the incoming
