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 need
to be reviewed and followed.
Safety Cautions
To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment observe the following
precautions:
•Observe and follow service markings.
•Do not service any product except as explained in the system documentation.
•Opening or removing covers that are marked with the triangular symbol with a lightning bolt may expose the
user to electrical shock.
oOnly 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:
oDamage to the power cable, extension cable, or plug.
oAn object has fallen into the product.
oThe product has been exposed to water.
oThe product has been dropped or damaged.
oThe product does not operate correctly when the operating instructions are correctly followed.
•Keep your system away from radiators and heat sources. Also, do not block cooling vents.
•Do not spill food or liquids on system components, and never operate the product in a wet environment. If the
system gets wet, see the appropriate section in the troubleshooting guide or contact your trained service
provider.
•Do not push any objects into the openings of the 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
unsure of the type of power source required, consult your service provider or local power company.
•To help avoid damaging the system, be sure the voltage selection switch (if provided) on the power supply is
set to match the power available at the Switch’s location:
o115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such
as South Korea and Taiwan
o100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
o230 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 your location.
•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's
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 using an extension cable is necessary, 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 the system from sudden, transient increases and decreases in electrical power, use a surge
suppressor, line conditioner, or uninterruptible power supply (UPS).

DGS-3000 Series Gigabit Ethernet Switch Web UI Reference Guide

•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:
oInstall the power supply before connecting the power cable to the power supply.
oUnplug the power cable before removing the power supply.
oIf 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.
CAUTION: Risk of explosion if the battery is replaced by an incorrect battery type. Dispose of used

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.
CAUTION: 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 rack on its slide assemblies at one time. The weight of more than
one extended component could cause the rack to tip over and may result in serious injury.
•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 proper airflow is provided to components in the rack.
•Do not step on or stand on any component when servicing other components in a rack.
NOTE: 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.
CAUTION: 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
uncertain that suitable grounding is available.

CAUTION: The system chassis must be positively grounded to the rack cabinet frame. Do not attempt to
connect power to the system until grounding cables are connected. Completed power and safety ground
wiring must be inspected by a qualified electrical inspector. An energy hazard will exist if the safety
ground cable is omitted or disconnected.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside the system. To prevent static damage, discharge static
electricity from your body before touching any of the electronic components, such as the microprocessor. This can be
done by periodically touching an unpainted metal surface on the chassis.
The following steps can also be taken prevent damage from electrostatic discharge (ESD):
1. When unpacking a static-sensitive component from its shipping carton, do not remove the component from
the antistatic packing material until ready to install the component in the system. Just before unwrapping the
antistatic packaging, be sure to discharge static electricity from your body.
2. When transporting a sensitive component, first place it in an antistatic container or packaging.
3. Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads, workbench pads
and an antistatic grounding strap.

Web-based User Interface
Web Pages
Introduction
Most software functions of the DGS-3000 Series switches can be managed, configured and monitored via the
embedded web-based (HTML) interface. Manage the Switch from remote stations anywhere on the network through a
standard browser. The browser acts as a universal access tool and can communicate directly with the Switch using
the HTTP protocol.
Login to the Web Manager
To begin managing the Switch, simply run the browser installed on your computer and point it to the IP address you
have defined for the device. The URL in the address bar should read something like: http://123.123.123.123, where
the numbers 123 represent the IP address of the Switch.
NOTE: The factory default IP address is 10.90.90.90.
This opens the management module's user authentication window, as seen below.
