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.

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.
