to your Ethernet network.
Terms/Usage
For simplicity, this documentation uses the terms “Switch” (first
letter upper case) to refer to this 26-Port 10/100/1000Mbps
Gigabit Ethernet Switch, and “switch” (first letter lower case) to
refer to Ethernet switches in general.

INTRODUCTION
This chapter describes the features of the Switch. This section
also provides some background information about Gigabit
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 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 guarantee 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.

4
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 are essential to coping with the network bottlenecks that
frequently develop as computers and their busses get faster and
more users using 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 supports 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.
The phenomenal bandwidth delivered by Gigabit Ethernet was
the most cost-effective method to take advantage of today’s
rapidly improving switching and routing internetworking
technologies. And with expected advances in silicon technology

5
and digital signal processing that enabled 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.
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 different segments, 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

6
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.

items inside. The carton should contain the following items:
?? One 26-Port 10/100/1000Mbps Gigabit & Ethernet
Switch
?? One AC powercord, suitable for your area’s electrical
power connections

Installation
The site where you place the Switch may greatly affect its
performance. When installing, take the following into your
consideration:
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 sunlight.
Leave at least 10cm of space around the Switch 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.

Switch
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
equipments. Attach the mounting brackets on the Switch’s front
panel (one on each side) and secure them with the provided
screws.
Figure 2. Attaching the mounting brackets to the Switch

10
Then, use screws provided with the equipment rack to mount the
Switch to the rack.

Connecting Network Cable
The Switch supports 10/100/1000Mbps Gigabit Ethernet. It runs
full/half duplex transfer mode for 10/100Mbps and full duplex
transfer mode for 1000Mbps.
These ports are Auto-MDIX type port. They can auto transform
to MDI-II or MDI-X type, so you can make a connection using a
standard or a crossover cable.
AC Power
The Switch can be used with AC power supply 100~240V AC,
50~60 Hz. The Switch does not come with a Power ON/OFF
switch, so the Switch will automatically power on when it is
connected to an electrical outlet. The Switch’s power supply will
adjust to the local power source automatically and may be turned
on without having any LAN segment cables connected.
