About This Manual
This manual is divided into two general sections:
Basics - Provides a general introduction to the Switch, its hardware and management
features, as well as a guide to setting up the Switch hardware and initial configu-
ration.
Web Manager - Describes management and configuration of Switch features, following the
layout of the Switch Web Manager. Four of the Switch six main folders - Secu-
rity, Management, Monitoring, Maintenance, and Single IP Management have
separate chapters. Configuration is divided into two chapters, Basic Configura-
tion and Advanced Configuration.
Intended Readers
This Manual contains information useful for setup and management and of the KGS-3120 Switch. This
manual is intended for network managers familiar with network management concepts and terminol-
ogy.
Typographical Conventions
Convention Description
[ ] In a command line, square brackets indicate an optional entry. For
example: [copy filename] means that optionally you can type copy
followed by the name of the file. Do not type the brackets.
Bold font Indicates a button, a toolbar icon, menu, or menu item. For example:
Open the File menu and choose Cancel. Used for emphasis. May
also indicate system messages or prompts appearing on your
screen. For example: You have mail. Bold font is also used to
represent filenames, program names and commands. For example:
use the copy command.
Typewriter Font Indicates commands and responses to prompts that must be typed
exactly as printed in the manual.
Initial capital letter Indicates a window name. Names of keys on the keyboard have
initial capitals. For example: Click [Enter].
Italics Indicates a window name or a field. Also can indicate a variables or
parameter that is replaced with an appropriate word or string. For
example: type filename means that you should type the actual
filename instead of the word shown in italic.
Menu Name > Menu Option Menu Name > Menu Option indicates the menu structure. Device >
Port > Port Properties means the Port Properties menu option under
the Port menu option that is located under the Device menu.

Notes, Notices, and Cautions
A NOTE indicates important information that helps you make better use of your
device.
A NOTICE indicates either potential damage to hardware or loss of data and tells you
how to avoid the problem.
A CAUTION indicates a potential for property damage, personal injury, or death.
Safety Instructions
Use the following safety guidelines to ensure your own personal safety and to help protect your system
from potential damage. Throughout this safety section, the caution icon is used to indicate
cautions and precautions that you need to review and follow.
Safety Cautions
To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe the
followingprecautions.
• Observe and follow service markings.
* Do not service any product except as explained in your system documentation.
* Opening or removing covers that are marked with the triangular symbol with a lightning bolt may
expose you to electrical shock.
* Only a trained service technician should service components inside these compartments.
• If any of the following conditions occur, unplug the product from the electrical outlet and replace
the part or contact your trained service provider:
* The power cable, extension cable, or plug is damaged.
* An object has fallen into the product.
* The product has been exposed to water.
* The product has been dropped or damaged.
* The product does not operate correctly when you follow the operating instructions.
• Keep your system away from radiators and heat sources. Also, do not block cooling vents.
• Do not spill food or liquids on your system components, and never operate the product in a wet
environment. If the system gets wet, see the appropriate section in your troubleshooting guide or
contact your trained service provider.
• Do not push any objects into the openings of your system. Doing so can cause fire or electric
shock by shorting out interior components.
• Use the product only with approved equipment.
• Allow the product to cool before removing covers or touching internal components.
• Operate the product only from the type of external power source indicated on the electrical
ratings label. If you are not sure of the type of power source required, consult your service
provider or local power company.

-10-
• To help avoid damaging your system, be sure the voltage selection switch (if provided) on the
power supply is set to match the power available at your location:
* 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries
such as South Korea and Taiwan
* 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
* 230 V/50 Hz in most of Europe, the Middle East, and the Far East
• Also be sure that attached devices are electrically rated to operate with the power available in
yourlocation.
• Use only approved power cable(s). If you have not been provided with a power cable for your
system or for any AC-powered option intended for your system, purchase a power cable that is
approved for use in your country. The power cable must be rated for the product and for the
voltage and current marked on the product electrical ratings label. The voltage and current rating
of the cable should be greater than the ratings marked on the product.
• To help prevent electric shock, plug the system and peripheral power cables into properly
grounded electrical outlets. These cables are equipped with three-prong plugs to help ensure
proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you
must use an extension cable, use a 3-wire cable with properly grounded plugs.
• Observe extension cable and power strip ratings. Make sure that the total ampere rating of all
products plugged into the extension cable or power strip does not exceed 80 percent of the
ampere ratings limit for the extension cable or power strip.
• To help protect your system from sudden, transient increases and decreases in electrical power,
use a surge suppressor, line conditioner, or uninterruptible power supply (UPS).
• Position system cables and power cables carefully; route cables so that they cannot be stepped
on or tripped over. Be sure that nothing rests on any cables.
• Do not modify power cables or plugs. Consult a licensed electrician or your power company for
site modifications. Always follow your local/national wiring rules.
• When connecting or disconnecting power to hot-pluggable power supplies, if offered with your
system,observe the following guidelines:
* Install the power supply before connecting the power cable to the power supply.
* Unplug the power cable before removing the power supply.
* If the system has multiple sources of power, disconnect power from the system by unplugging all
power cables from the power supplies.
• Move products with care; ensure that all casters and/or stabilizers are firmly connected to the
system. Avoid sudden stops and uneven surfaces.
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.
Installing systems in a rack without the front and side stabilizers installed could cause
the rack to tip over, potentially resulting in bodily injury under certain circumstances.
Therefore, always install the stabilizers before installing components in the rack. After
installing system/components in a rack, never pull more than one component out of the
