Chapter 1: Introduction
Gigabit Ethernet technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet. It uses the same packet
structure, format, and support for CSMA/CD protocol, full duplex, and flow
control, but with a tenfold increase in theoretical throughput over 100-Mbps
Fast Ethernet and a hundredfold increase over 10-Mbps Ethernet. Because 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 are
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.
Because 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 do not 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 (from one port
to another) is automatically forwarded by the switch, without interfering with
any other segments (ports). This allows the total network capacity to be
multiplied, while still maintaining the same network cabling and adapter cards.

For Fast Ethernet or Gigabit Ethernet networks, a switch is an effective way of
eliminating problems of chaining hubs beyond the “two-repeater limit.” A
switch can be used to split parts of the network into different collision domains,
for example, making it possible to expand your Fast Ethernet network beyond
the 205-meter network diameter limit for 100BASE-TX networks. Switches
supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are
also ideal for bridging between existing 10Mbps networks and new 100Mbps
networks.
Switching LAN technology is an 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.
Switch descriptions
These unmanaged switches were designed for easy installation and high
performance in an environment where traffic on the network and the number
of users increase continuously.

■ Supports 2M bits data buffer per device.
■ Front-panel indicator LEDs.
Front-panel components
The front panels of the switches consist of LED indicators and fast Ethernet or
gigabit Ethernet ports. The number of LEDs, and the number and speed of the
ports, depends on the switch model selected.
Comprehensive LED indicators display the status of the switches and the
network.

Power This indicator will light steady green immediately after
the switch is powered on to indicate the ready state of
the device.
Link/Act This indicator lights green when the port is connected
to a Gigabit Ethernet, Fast Ethernet, or Ethernet station.
If the indicator is blinking green, data is either being
transmitted or received.
Speed This LED indicator is dark when the port is connected
to a 10 Mbps Ethernet or 100 Mbps Fast Ethernet
station, and it lights green when the port is connected
to a 1000 Mbps Gigabit Ethernet station (on gigabit
capable models).
Duplex This LED indicator lights green when the port active in
full duplex mode.
Rear panel description
The rear panels of the switches consists of the power connector only, and are
not shown. The AC power connector (Gateway 7201-16, 7201-24, 7201-24.2,
and 7401-24) is a standard three-pronged connector that supports the power
cord. Plug one end of the power cord into the socket and the other end into
the power outlet. The switch automatically adjusts its power setting to any
supply voltage in the range from 100 ~ 240 VAC at 50 ~ 60 Hz.
The rear panel of the Gateway 7401-05 and 7401-08 switches consists of the
DC power jack (AC power adapter supplied). The AC power adapter
automatically adjusts its power setting to any supply voltage in the range from
100 ~ 240 VAC at 50 ~ 60 Hz.

Chapter 1: Introduction
Side panel description
The sides of the system provide heat vents that help to dissipate heat. Do not
block these openings, and leave at least 6 inches (152.3 mm) of space at the
rear and sides of the switch for correct ventilation.
Warning Without correct heat dissipation and air
circulation, system components might overheat,
which could lead to system failure.

Chapter 2: Installation
Before you connect to the network
The site where you install the switch may greatly affect its performance. Please
follow these guidelines for setting up the switch:
■ Install the switch on a sturdy, level surface that can support at least 6.6
lbs. (3 kg) of weight. Do not place heavy objects on the switch.
■ The power outlet should be within 6 feet (1.82 meters) of the switch.
■ Visually inspect the power cord and see that it is fully secured to the AC
power port.
■ Make sure that there is correct heat dissipation from and adequate
ventilation around the switch. Leave at least 6 inches (152.3 mm) of space
at the front and rear of the switch for ventilation.
■ Install the switch in a fairly cool and dry place for the acceptable
temperature and humidity operating ranges.
■ Install the switch in a site free from strong electromagnetic field generators
(such as motors), vibration, dust, and direct exposure to sunlight.
■ When installing the switch on a level surface, attach the rubber feet to the
bottom of the device. The rubber feet cushion the switch, protect the casing
from scratches, and prevent it from scratching other surfaces.

switches
Package contents
Open the shipping carton and carefully unpack its contents. The carton should
contain the following items:
■ One Gateway 7401-05 5-port, or 7401-08 8-Port 10/100/1000BASE-T
Gigabit Ethernet switch
■ Four rubber feet with adhesive backing
■ One external power adapter
■ This manual
If any item is found missing or damaged, contact Gateway for a replacement.
Attaching the rubber feet
Position and apply rubber feet to the underside of the switch.
Provide for adequate ventilation
Warning Do not place any device on top of the switch or place the
switch on top of any device or object that will block the free
flow of air through the ventilation slots on the sides, top,
and bottom of the switch’s case. In addition, care should
be taken not to locate the switch next to, on top of, or
underneath any device that generates a significant amount
of heat. For the switch to perform at its optimal level, the
switch must have adequate ventilation to prevent the switch
from overheating and becoming damaged.
Power on
Plug one end of the AC power adapter into the power connector on the switch
and the other end into the local power source outlet.
