2. Introduction
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 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.
This section describes the features of the 8-Port 1000BASE-T Gigabit Ethernet
Switch, as well as providing some background information about Gigabit
Ethernet and switching technology.

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 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.

Setup
The setup of the Switch can be performed using the following steps:
Install the Switch in a fairly cool and dry place. See Technical
Specification for the acceptable operation temerature and humidity
ranges.
Install the Switch in a site free from strong electromagnetic
source,vibration, dust,and direct sunlight.
Leave at least 10cm of space at the left and right hand side of the Switch
for ventilation.
Visually inspect the DC power jack and make sure that it is fully secured
to the power adapter.

4. Identifying External Components
The front panel of the Switch consists of eight 1000BASE-T ports and LED
indicators.
This chapter describes the front panel, rear panel and LED indicators of the
Switch
Front Panel

1000BASE-T Ports:
Eight Gigabit Ethernet ports of 10/100/1000Mbps Auto-Negotiation interface.
LED Indicators
Comprehensive LED indicators display the conditions of the Switch and status
of the network. A description of these LED indicators follows (see LED
Indicators).
DC Power Jack:
Power is supplied through an external AC power adapter. Check the technical
specification section for information about the AC power input voltage.
Rear Panel
The rear panel of the Switch consists of an DC power connector. The following
figure shows the rear panel of the Switch.

The LED indicators of the Switch include Power, Link/Act, 1000Mbps and
100Mbps. The following shows the LED indicators for the Switch along with an
explanation of each indicator.
The Switch LED indicators
LED Indicators
This indicator lights green when the Switch is receiving power, otherwise,
it is off.
These LED indicators are lighted up when there is a secure connection (or
link) to the desired port. The LED indicators blinking whenever there is
reception or transmission (i.e. ActivityACT) of data occurring at a port.
These LED indicators are lighted up when there is a secure connection (or
link) to 1000Mbps Gigabit Ethernet device at the desired port.
These LED indicators are lighted up when there is a secure connection (or
link) to 100Mbps Fast Ethernet device at the desired port.
Power:
Link/ACT:
1000Mbps:
100Mbps:
When the connection (or link) is 10Mbps, both of 1000Mbps and 100Mbps LED
indicators are off.
