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.

Switch descriptions
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.

Connecting to an end node
For the Gateway 7201-16 and 7201-24 switches, end nodes include computers
with 10, 100, or 10/100 Mbps RJ-45 Ethernet/Fast Ethernet Network Interface
Cards (NIC). For the Gateway 7401-05, 7401-08, 7401-24, and 7201-24.2
switches, end nodes include computers with 10, 100, or 1000 Mbps RJ-45
Ethernet/Fast Ethernet/Gigabit Network Interface Cards (NIC). End nodes can
also include most routers.
An end node can be connected to the switch through a twisted-pair Category
3, 4, or 5 UTP/STP cable. The end node should be connected to any port on
the switch. End nodes with Gigabit capability should be connected to the
Gigabit capable ports on the Gateway 7201.24.2 switch.
The Link/Act LEDs for each UTP port light green when the port is connected
to a Gigabit Ethernet, Fast Ethernet, or Ethernet station. If the indicator is
blinking green, data is being transmitted or received.

Some products are equipped with a three-wire power cord to make sure that the product is
correctly grounded when in use. The plug on this cord will fit only into a grounding-type outlet.
This is a safety feature. If you are unable to insert the plug into an outlet, contact an electrician
to install the appropriate outlet.
■
If you use an extension cord with this switch, make sure that the total ampere rating on the
products plugged into the extension cord does not exceed the extension cord ampere rating.
General precautions for rack-mountable products
Observe the following precautions for rack stability and safety. Also refer to the rack installation
documentation accompanying the system and the rack for specific caution statements and
procedures.
Systems are considered to be components in a rack. Thus, “component” refers to any system as
well as to various peripherals or supporting hardware.
Warning
High voltages can enter your computer through both the
power cord and the modem connection. Protect your
computer by using a surge protector. If you have a
telephone modem, use a surge protector that has a
modem jack. If you have a cable modem, use a surge
protector that has an antenna/cable jack. During an
electrical storm, unplug both the surge protector and the
modem.
Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the
floor, and that the full weight of the rack rests on the floor. Install front and side stabilizers on a
single rack or front stabilizers for joined multiple racks before working on the rack.
Always load the rack from the bottom up, and load the heaviest item in the rack first.
Make sure that the rack is level and stable before extending a component from the rack.
Use caution when pressing the component rail release latches and sliding a component into or out
of a rack; the slide rails can pinch your fingers.
After a component is inserted into the rack, carefully extend the rail into a locking position, and
then slide the component into the rack.
Do not overload the AC supply branch circuit that provides power to the rack. The total rack load
should not exceed 80 percent of the branch circuit rating.
Ensure that correct airflow is provided to components in the rack.

Important safety information
Do not step on or stand on any component when servicing other components in a rack.
Important
A qualified electrician must perform all connections to DC
power and to safety grounds. All electrical wiring must
comply with applicable local or national codes and
practices.
Warning
Never defeat the ground conductor or operate the
equipment in the absence of a suitably installed ground
conductor. Contact the appropriate electrical inspection
authority or an electrician if you are uncertain that suitable
grounding is available.
Warning
The switch chassis must be positively grounded to the rack
cabinet frame. Do not attempt to connect power to the
switch until grounding cables are connected. Completed
power and safety ground wiring must be inspected by a
qualified electrical inspector. An electrical hazard will exist
if the safety ground cable is omitted or disconnected.
Preventing static electricity discharge
The components inside your computer are extremely sensitive to static electricity, also known as
electrostatic discharge (ESD).
Warning
ESD can permanently damage electrostatic
discharge-sensitive components in your computer. Prevent
ESD damage by following ESD guidelines every time you
open the computer case.
Warning
To avoid exposure to dangerous electrical voltages and
moving parts, turn off your computer and unplug the power
cord and modem and network cables before opening the
case.
Before opening the computer case, follow these guidelines:
■
Turn off your computer.
■
Wear a grounding wrist strap (available at most electronics stores) and attach it to a bare metal
part of your computer.
Warning
To prevent risk of electric shock, do not insert any object
into the vent holes of the power supply.

Appendix B: Safety, Regulatory, and Legal Information
■
Touch a bare metal surface on the back of the computer.
■
Unplug the power cord and the modem and network cables.
Before working with computer components, follow these guidelines:
■
Avoid static-causing surfaces such as carpeted floors, plastic, and packing foam.
■
Remove components from their antistatic bags only when you are ready to use them. Do not lay
components on the outside of antistatic bags because only the inside of the bags provide
electrostatic protection.
■
Always hold expansion cards by their edges or their metal mounting brackets. Avoid touching
the edge connectors and components on the cards. Never slide expansion cards or components
over any surface.
Care during use
■
Do not walk on the power cord or allow anything to rest on it.
■
Do not spill anything on the switch. The best way to avoid spills is to avoid eating and drinking
near your switch.
■
Some products have a replaceable CMOS battery on the system board. There is a danger of
explosion if the CMOS battery is replaced incorrectly. Replace the battery with the same or
equivalent type recommended by the manufacturer. Dispose of batteries according to the
manufacturer’s instructions.
■
When a computer is turned off, a small amount of electrical current still flows through it. To
avoid electrical shock, always unplug all power cables and modem cables from the wall outlets
before cleaning the switch.
■
Unplug the switch from the wall outlet and refer servicing to qualified personnel if:
■
The power cord or plug is damaged.
■
Liquid has been spilled into the switch
■
The switch does not operate correctly when the operating instructions are followed.
■
The switch was dropped or the case is damaged.
■
The switch performance changes.
Replacement parts and accessories
Use only replacement parts and accessories recommended by Gateway.
Important
Warning
Do not use Gateway products in areas classified as
hazardous locations. Such areas include patient care
areas of medical and dental facilities, oxygen-laden
environments, or industrial facilities.
To reduce the risk of fire, use only No. 26 AWG or larger
telecommunications line cord.
