designed to provide reasonable protection against
harmful interference when the equipment is
operated in a commercial environment. This
equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with this user’s guide, may cause
harmful interference to radio communications.
Operation of this 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/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.

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).

NTRODUCTION

This chapter describes the features of the 16-Port 10/100Mbps

Fast Ethernet Smart Switch and some background
information about Ethernet/Fast Ethernet and
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 non­disruptive, smooth evolution from the current
10BASE-T technology. The non-disruptive and
smooth evolution nature, and the dominating
potential market base, virtually guarantee cost­effective 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

3

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

4

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.

VLAN (Virtual Local Area Network)

A VLAN is a group of end-stations that are not constrained by

their physical location and can communicate as if
a common broadcast domain, a LAN. The
primary utility of using VLAN is to reduce
latency and need for routers, using faster
switching instead. Other VLAN utility include:



Security is increased with the reduction of opportunity in



VLANs can be used to create multiple broadcast domains, thus

Port-based (or port-group) VLAN is the common method of

Security

eavesdropping on a broadcast network because
data will be switched to only those confidential
users within the VLAN.

implementing a VLAN, and is the one supplied in
the Switch. Each Switch port can belong from one
to sixteen VLAN.
