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 Levelone GSW-1674T/2474T

16/24-port 10/100/1000 Mbps Gigabit Ethernet Web Smart Switch

and some background information about Ethernet/ Fast Ethernet/

Gigabit Ethernet switching technology.

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

is 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 enables fast optical fiber connections to support

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.

In addition, the phenomenal bandwidth delivered by Gigabit Ethernet

is the most cost-effective method to take advantage of today and

tomorrow’s rapidly improving switching and routing internetworking

technologies. And with expected advances in the coming years in

silicon technology and digital signal processing that will enable

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.

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

guarantees 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.

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.
