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 levelof 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. 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. Todayswitches are ideal

solutionsto 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:

?? 24-port 10/100BASE Ethernet Switch with RJ-45

connectors

?? SupportsAuto-negotiation for speed and duplex

modes on each port

?? Supports Auto-MDI/MDI-X on each port

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.
