User’s Guide

FCC Warning
This equipment has been tested and found to comply with the
limits 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 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 supplycircuit 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 section describes the features of the Switch, as well as
providing some basic information about Gigabit Ethernet and
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 100Mbps
Fast Ethernet and a hundredfold increase over 10Mbps
Ethernet. Since it is 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.
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 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.
Switching Technology
Another key development pushing the limits of Ethernet
technology is in the field 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 making it
possible for a local area network to be divided into different
segments which don’t compete with each other for network
transmission capacity, giving a decreased load on each.
The switch acts as a high-speed selective bridge between the
individual segments. The switch automatically forwards traffic
that needs to go from one segment to another, without
interfering with any other segments. This allows the total
network capacity to be 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
