Safety Cautions
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.
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.
•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:
•Damage to the power cable, extension cable, or plug.
•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 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:
•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 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).
•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.
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 weig
ht 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.
CAUTION:When mounting the Switch on a cement wall, a proper concrete sleeve
anchor should be used, such as the one that is included in the optional D-Link Wall Mount
kit (DRE-KIT018).
Lithium Battery Precaution
CAUTION: Incorrectly replacing the lithium battery of the Switch may cause the battery to
explode. Replace this battery only with the same or equivalent type recommended by the
manufacturer. Discard used batteries according to the manufacturer’s instructions.
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 Switch Configuration
Introduction
Logging onto the Web Manager
Web-Based User Interface
Introduction
All software functions of the Switch 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, such as Internet Explorer 5.5 or
later, Netscape 8.0 or later, Firefox 2.0 or later, or Apple Safari 3.0. The browser acts as a universal access tool and can
communicate directly with the Switch using the HTTP protocol.
The Web-based management module and the Console program (and Telnet) are different ways to access the same internal
switching software and configure it. Thus, all settings encountered in web-based management are the same as those found in the
console program.
Logging onto 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.
