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

INTRODUCTION
This section describes the features of the 8-Port
10/100/1000Mbps Gigabit Ethernet Switch, as well as providing
some background 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 100-Mbps
Fast Ethernet and a hundredfold increase over 10-Mbps
Ethernet. Since it is compatible with all 10-Mbps 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
4
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. Traffic that needs to go from one segment
5
to another is automatically forwarded by the switch, 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
characterized by higher latencies. Routers have also been used
to segment local area networks, but the cost of a router and the
setup and maintenance required make routers relatively
impractical. Today’s switches are an ideal solution to most
kinds of local area network congestion problems.
Features
The 8-Port 10/100/1000Mbps Gigabit Ethernet Switch was
designed for easy installation and high performance in an
environment where traffic on the network and the number of
users increase continuously.

UNPACKING AND SETUP
This chapter provides unpacking and setup information for the
Switch.
Unpacking
Open the shipping carton of the Switch and carefully unpack its
contents. The carton should contain the following items:
l One 8-Port 10/100/1000Mbps Gigabit Ethernet Switch
l Four rubber feet with adhesive backing
l One AC power cord
l This user’s guide
If any item is found missing or damaged, please contact your
local reseller for replacement.
Setup
The setup of the Switch can be performed using the following
steps:
l The surface must support at least 5 kg.
9
l The power outlet should be within 1.82 meters (6 feet)
of the device.
l Visually inspect the power cord and see that it is
secured fully to the AC power connector.
l Make sure that there is proper heat dissipation from
and adequate ventilation around the Switch. Do not
place heavy objects on the Switch.
Desktop Installation
When installing the Switch on a desktop or shelf, the rubber feet
included with the device must be attached first. Attach these
cushioning feet on the bottom at each corner of the device.
Allow enough ventilation space between the device and the
objects around it.

Rack Installation (optional)
The 8-Port 10/100/1000Mbps Gigabit Ethernet Switch can be
mounted in an EIA standard size, 19-inch rack, which can be
placed in a wiring closet with other equipment. To install, attach
the mounting brackets on the Switch’s front panel (one on each
side) and secure them with the screws provided.
11

Connecting Network Cable
The 8-Port 10/100/1000Mbps Gigabit Ethernet Switch
supports eight 10/100/1000Mbps Gigabit Ethernet ports. These
ports runs both half duplex and full duplex while they’re
running in 10Mbps or 100Mbps and runs full duplex while
they’re running in 1000Mbps.
These ports are Auto-MDI type port, and they can auto
transform to MDI-II or MDI-X type, so you can just make an
easy connection without worrying if you are using a standard or
crossover cable.
12
AC Power
The 8-port Gigabit Ethernet Switch can be used with AC power
sources 100-240V AC, 50-60 Hz. The power supply of the
Switch will adjust to the local power source automatically and
may be turned on without having any or all LAN segment cables
connected.
