FCC Warning
This equipment has been tested and found to comply with the
regulations for a Class A digital device, pursuant to Part 15 of the
FCC Rules. These limits are 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 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 TEG2248WS 48Port
10/1000MbpsWebSmartSwitchw/4GigabitPortsand2MiniGBIC
Slots and some background information about Ethernet/Fast
Ethernet/GigabitEthernetswitchingtechnology.
GigabitEthernetTechnology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the
same packet structure, format, and support for CSMA/CD protocol,
fullduplex,flowcontrol,andmanagementobjects,butwithatenfold
increaseintheoretical throughputover 100Mbps Fast Ethernetand
ahundredfoldincreaseover10MbpsEthernet.Sinceitis
compatible
with all 10Mbps and 100Mbps Ethernet environments, Gigabit
Ethernet provides a straightforward upgrade without wasting a
company’s existing investment in hardware, software, and trained
personnel.
Gigabit Ethernet enables fast optical fiber connections to support
video conferencing, complex imaging, and similar dataintensive
applications.Likewise,sincedatatransfers

Inaddition,thephenomenalbandwidthdeliveredbyGigabitEthernet
is the most costeffective method to take advantage of today and
tomorrow’srapidly improving switchingandrouting 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 twistedpair
(UTP) cabling, outfitting your network with a powerful 1000Mbps
capablebackbone/serverconnectioncreatesaflexiblefoundationfor
thenextgenerationofnetworktechnologyproducts.
FastEthernetTechnology
The growing importance of LANs and the increasing complexity of
desktop computing applications are fueling the need for high
performance networks. A number of highspeed LAN technologies
have been proposed to provide greater bandwidth and improve
client/server response times.Among them, 100BASET (Fast
Ethernet) provides a nondisruptive, smooth
evolution from the
current 10BASET technology.The nondisruptive and smooth
evolutionnature,andthedominatingpotentialmarketbase,virtually
guarantees costeffective and high performance Fast Ethernet
solutions.
100MbpsFastEthernetisastandardspecifiedbytheIEEE802.3LAN
committee.It is an extension of the 10Mbps
Ethernet standard
with the ability to transmit and receive data at 100Mbps, while
maintainingtheCSMA/CDEthernetprotocol.Sincethe100MbpsFast
Ethernetiscompatiblewithallother10MbpsEthernetenvironments,
it provides a straightforward upgrade and takes advantage of the
existinginvestmentinhardware,software,andpersonneltraining.

SwitchingTechnology
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
LANsegments.
Switching is a costeffective way of increasing the total network
capacity
available to users on a local area network.A switch
increasescapacityanddecreases network loadingby dividinga local
area network into different segments, which don’t compete with
eachotherfornetworktransmissioncapacity.
The switch acts as a highspeed selective bridge between the
individualsegments.Theswitch,
withoutinterferingwithanyother
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
adaptercards.
Switching LAN technology is a marked improvement over the
previousgenerationofnetworkbridges,
whichwerecharacterizedby
higherlatencies.Routershavealsobeenusedtosegmentlocalarea
networks, but the cost of a router, the setup and maintenance
requiredmakeroutersrelativelyimpractical.Todayswitchesarean
ideal solution to most kinds of local area network congestion
problems.

VLAN(VirtualLocalAreaNetwork)
A VLAN is a group of endstations that are not constrained by their
physical location and can communicate as if a common broadcast
domain,aLAN.TheprimaryutilityofusingVLANistoreducelatency
and need for routers, using faster switching instead. Other VLAN
utilityincludes:

UNPACKINGANDINSTALLATION
This chapter provides unpackingand installation information for the
Switch.
Unpacking
Open the shipping cartons of the Switch and carefully unpacks its
contents.Thecartonshouldcontainthefollowingitems:

Installation
The site where you install the hub stack may greatly affect its
performance.Wheninstalling,considerthefollowingpointers:
Install the Switch in a fairly cool and dry place.See Technical
Specificationsfortheacceptabletemperatureandhumidityoperating
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 and rear of the hub for
ventilation.
10
Install the Switch on a sturdy, level surface that can support its
weight, or in an EIA standardsizeequipmentrack.For information
onrackinstallation,seethenextsection,RackMounting.
Wheninstallingthe Switch on a level surface,attach the rubber feet
