NTRODUCTION
This chapter describes the features of the Switch and some
background information about Ethernet/Fast Ethernet/Gigabit Ethernet
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.
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
1
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 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 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 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.
2
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 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.

NPACKING AND INSTALLATION
This chapter provides unpacking and installation information for the
Switch. To avoid causing any damage to the Switch, we recommend
that you read this chapter carefully before starting installation.
Unpacking
Open the shipping carton of the Switch and carefully unpack the items
inside. The carton should contain the following items:
The Smart Gigabit Ethernet Switch
One AC power cord, suitable for your area’s electrical power
connections
Console Cable: RS232 9pin (male) to 9pin (male)

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 site free from strong electromagnetic field
generators (such as motors), vibration, dust, and direct exposure
to sunlight.
When installing the Switch on a level surface, attach the adhesive
Leave at least 10cm of space at the front and rear of 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.
rubber pads to the bottom. The rubber pads cushion the Switch
and protect its case from scratching.
6
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 to both sides of the Switch (one at each side),
and secure them with the provided screws.
Then, use screws provided with the equipment rack to mount the
Switch in the rack.

ONNECTING THE SWITCH
Referring to the cable specification below, use appropriate cables that
meet your speed and cabling requirements when connecting the
Switch to your network.
The LAN card capabilities play an important role. If any status LED
indicator is not shining after making a proper connection, check the
PC LAN card, the cable, the Switch conditions and connections.
Connecting Step-by-Step
Step 1:
First, ensure the power of the switch and end devices is turned off.
Step 2:
Step 3:
Step 4:
Consult Cable Specifications Table on next page for cabling requirements
based on connectors and speed.
Connect one end of the cable to the switch and the other end to a desired
device.
When the connections between two end devices are made successfully,
turn on the power and the switch is operational.

ONFIGURING THE SWITCH
This chapter explains how to configure the Switch to enable its smart
functions.
Port Speed & Duplex Mode
By default, the Switch determines the transmission mode by autonegotiation for any new twisted-pair or fiber connection after
attaching the proper cable to a specific port.
For 10/100/1000Mbps RJ-45 ports, if the attached device does not
support auto-negotiation or has auto-negotiation disabled, an autosensing process is initiated to select speed (10Mbps or 100Mbps or
1000Mbps) and duplex mode (half or full duplex).
For 1000Mbps SC ports, if the attached device does not support autonegotiation or has auto-negotiation disabled, an auto-sensing process
is initiated to select duplex mode (half or full duplex).
Configuration via Console Port
Attach one end of a serial cable to the console port on the Switch, and
the other end to a RS232 port on a remote workstation.
The configuration of the Switch is enabled through the console port.
However, it is necessary to configure a terminal emulation program,
i.e. NetTerm, HyperTerminal.
