INTRODUCTION
This section describes the features of the LevelOne
GSW-0801T 8Port 10/100/1000TGigabit Ethernet
Switch, as well as giving 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
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

4
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

5
transmission capacity, giving a decreased load on
each.
The LevelOne GSW-0801T 8Port 10/100/1000T
Gigabit Ethernet 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 LevelOne GSW-0801T
8Port 10/100/1000TGigabit Ethernet 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.

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:
♦One LevelOne GSW-0801T 8Port 10/100/1000T
Gigabit Ethernet Switch
♦Accessory pack: 2 mounting brackets and screws
♦Four rubber feet with adhesive backing
♦One AC power cord
♦This user’s guide
If any item is found missing or damaged, please
contact your local reseller for replacement.
Setup
The setup of the LevelOne GSW-0801T 8Port
10/100/1000TGigabit Ethernet Switch can be
performed using the following steps:
♦The surface must support at least 5 kg.

8
♦The power outlet should be within 1.82 meters (6
feet) of the device.
♦Visually inspect the power cord and see that it is
secured fully to the AC power connector.
♦Make sure that there is proper heat dissipation from
and adequate ventilation around the Switch. Do not
place heavy objects on the Switch.
Desktop or Shelf Installation
When installing the LevelOne GSW-0801T 8Port
10/100/1000TGigabit Ethernet Switch on a desktop or
shelf, the rubber feet included with the device must be
first attached. 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
The LevelOne GSW-0801T 8Port 10/100/1000T
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.
