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 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.
• To help avoid damaging your system, be sure the voltage 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
ix
xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch
• 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
• –48 VDC for DC power supply unit on DES-3828DC DC only
• 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 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.
x
xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch
• 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,
regional 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 you are
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. A qualified electrical inspector must inspect completed
power and safety ground wiring. An energy hazard will exist if the safety
ground cable is omitted or disconnected.
CAUTION: Do not replace the battery with an incorrect type. The risk of
explosion exists if the replacement battery is not the correct lithium battery
type. Dispose of used batteries according to the instructions.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your system. To prevent static damage, discharge static electricity from your body before you touch any of the electronic components, such as
the microprocessor. You can do so by periodically touching an unpainted metal surface on the chassis.
You can also take the following steps to 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 you are ready to install the component in
your system. Just before unwrapping the antistatic packaging, be sure to discharge static
electricity from your body.
xi
xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch
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.

Section 1
The DES-3800 series is a member of the D-Link xStack switch family. xStack is a complete family of
stackable devices that ranges from edge 10/100Mbps switches to core Gigabit switches. xStack
provides unsurpassed performance, fault tolerance, scalable flexibility, robust security, standard-based
interoperability and an impressive support for 10Gigabit technology to future-proof departmental and
enterprise network deployments with an easy migration path.
Gigabit Ethernet Technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format,
and support for CSMA/CD protocol, full duplex, flow control, and management objects, but with a
tenfold increase in theoretical throughput over 100Mbps Fast Ethernet and a one hundred-fold increase
over 10Mbps Ethernet. Since it is compatible with all 10Mbps and 100Mbps 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
using 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 sub networks.
Gigabit Ethernet enables fast optical fiber connections to support video conferencing, complex
imaging, and similar data-intensive applications. Likewise, since 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.
In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective
method to take advantage of today and tomorrow's rapidly improving switching and routing internetworking technologies.

Switch Description
The Switch is equipped with unshielded twisted-pair (UTP) cable ports providing dedicated 10 or 100
Mbps bandwidth. The Switch has 24 UTP ports and Auto MDI-X/MDI-II convertible ports that can be
used for unlinking to another switch. These ports can be used for connecting PCs, printers, servers,
hubs, routers, switches and other networking devices. The dual speed ports use standard twisted-pair
cabling and are ideal for segmenting networks into small, connected sub networks for superior
performance. Each 10/100 port can support up to 200 Mbps of throughput in full-duplex mode. In
addition, the Switch has 2 combo 1000 Base-T/SFP ports on the front panel and two 1000 Base-T on
