equipment in a residential area is likely to cause harmful

interference, in which case the user will be required to correct the

interference at his or her own expense.

CE Mark Warning

This is a Class A product. In a domestic environment, this

product may cause radio interference, in which case the user may

be required to take adequate measures.

VCCI Warning

This is a product of VCCI Class A Compliance.

UL Warning

a) Elevated Operating Ambient Temperature- If installed in a

closed or multi-unit rack assembly, the operating ambient

temperature of the rack environment may be greater than room

ambient. Therefore, consideration should be given to installing

the equipment in an environment compatible with the

manufacturer's maximum rated ambient temperature (Tmra).

b) Reduced Air Flow- Installation of the equipment in a rack

should be such that the amount of air flow required for safe

operation of the equipment is not compromised.

c) Mechanical Loading- Mounting of the equipment in the rack

should be such that a hazardous condition is not achieved due to

uneven mechanical loading.

d) Circuit Overloading- Consideration should be given to the

connection of the equipment to the supply circuit and the effect

that overloading of circuits might have on over current protection

and supply wiring. Appropriate consideration of equipment

nameplate ratings should be used when addressing this concern.

e) Reliable Earthing- Reliable earthing of rack-mounted

equipment should be maintained. Particular attention should be

given to supply connections other than direct connections to the

branch circuit (e.g., use of power strips).

INTRODUCTION

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.

AirLive Ether-FSH2402NT User’s Manual

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

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

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.
