INTRODUCTION

This chapter describes the features of the Switch and some
background information about Ethernet/Fast 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
in the years to come.

100Mbps Fast Ethernet is a new 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 10Mbps Ethernet and 100Mbps Fast
Ethernet environments, it provides a straightforward network 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 bridge 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.

For Fast Ethernet networks, a switch is an effective way of eliminating
problems of chaining hubs beyond the “repeater-counts” limitation. A
switch can be used to split parts of the network into different collision

domains, 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 the
existing 10Mbps networks and the 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, the setup and maintenance required

make routers relatively impractical. Today switches are ideal

solutions to most kinds of local area network congestion problems.

Features

The Switch were designed for easy installation and high performance
in an environment where traffic on the network and the number of

user increase continuously.
The Switch with its rack size is specifically designed for middle to

large workgroups. The Switch provides immediate access to a rapidly
growing network through a wide range of user-reliable functions.

The Switch is ideal for deployment with multiple high-speed servers
for shared bandwidth 10Mbps or 100Mbps workgroups. With the

highest bandwidth 200Mbps (100Mbps full-duplex mode), any port
can provide workstation with a congestion-free data pipe for
simultaneous access to the server.

The Switch is expandable by cascading two or more switches
together. As all ports support 200Mbps, the Switch can be cascaded
from any port and to any number of switches.

The Switch is a perfect choice for site planning to upgrade to Fast
Ethernet in the future. Ethernet workgroups can connect to the
Switch now, and change adapters and hubs anytime later without

needing to change the Switch or reconfigure the network.
The Switch combine dynamic memory allocation with

store-and-forward switching to ensure that the buffer is effectively
allocated for each port, while controlling the data flow between the

transmit and receive nodes to guarantee against all possible packet
loss.

The Switch is an unmanaged 10/100 Fast Ethernet Switch that offers
solutions in accelerating small Ethernet workgroup bandwidth. Other
key features are:

If any item is found missing or damaged, please contact your local
reseller for replacement.

Installation

The site where you install the Switch stack may greatly affect its
performance. When installing, consider the following pointers:

Install the Switch in a fairly cool and dry place. See 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 at the front, rear, and both right and left
sides of the hub for ventilation. Do not block the vent holes on the
sides.

7

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.

Install the Switch on a level surface; on the bottom of the Switch,
attach one rubber pad on each corner. The rubber feet cushion the
Switch and protect the Switch’s housing from scratching.

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 side panels (one on each side)
with the provided screws.

Then, use screws provided with the equipment rack to mount each
switch on the rack.
