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.
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.

xStack®DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch
viii
•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
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.
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 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.

Introduction
Front Panel Components
LED Indicators
Rear Panel
Side Panel
The DGS-3600 Gigabit Ethernet switches are members of the D-Link xStack®family. Ranging from 10/100Mbps edge switches
to core gigabit switches, the xStack®switch family has been designed to deliver a system with fault tolerance, flexibility, port
density, robust security, and maximum throughput, with a user-friendly management interface for the networking professional.
This manual describes the installation, maintenance and configurations concerning members of the xStack®DGS-3600 Series.
These switches include: the DGS-3612, DGS-3612G, DGS-3627, DGS-3627G, and the DGS-3650. The xStack®DGS-3600
switches are similar in configurations and basic hardware and consequentially, most of the information in this manual will be
universal to the whole xStack®DGS-3600 Series. Corresponding screen pictures of the Web manager may be taken from any one
of these switches but the configuration will be identical, except for varying port counts.
The switches are equipped with unshielded twisted-pair (UTP) cable ports providing dedicated 10, 100 or 1000 Mbps bandwidth.
The DGS-3627 is equipped with twenty-four 10/100/1000BASE-T ports, and the DGS-3650 has forty-eight 10/100/1000BASE-T
ports, all of which are Auto MDI-X/MDI-II convertible ports that can be used for uplinking to another switch. The DGS-3612G is
equipped with twelve 100/1000Mbps SFP (Small Form Factor Portable) ports, in addition to four 1000BASE-T located on the
front panel. 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 10/100/1000 port can support up to 2000 Mbps of throughput in full-duplex mode. In addition, the
Switch has four 1000Mbps SFP combo ports located on the front panel.These gigabit combo ports are ideal for connecting to a
server or network backbone.
The DGS-3627G contains twenty-four 1000Mbps SFP (Small Form Factor Portable) ports, in addition to four 1000BASE-T
located on the front panel. The DGS-3612 contains twelve 10/100/1000BASE-T ports, all of which are Auto MDI-X/MDI-II
convertible ports that can be used for uplinking to another switch, and four 100/1000Mbps SFP (Small Form Factor Portable)
ports. The SFP combo ports are to be used with fiber-optical transceiver cabling in order to uplink various other networking
devices for a gigabit link that may span great distances. The SFP ports can also support full-duplex transmissions, have auto-
negotiation and can be used with DEM-210 (100FX-LC), DEM-211 (100FX-LC), DEM-310GT (1000BASE-LX), DEM-311GT
(1000BASE-SX), DEM-312GT2 (1000BASE-SX), DEM-314GT (1000BASE-LHX), DEM-315GT (1000BASE-ZX),
DEM-330T/R (WDM Transceiver) and the DEM-331T/R (WDM Transceiver) transceivers. These ports are referred to as
“combo” ports. That means both the SFP ports and the 1000BASE-T ports are numbered the same and cannot be used
simultaneously. Attempting to use the ports simultaneously will cause a link down status for the 1000BASE-T ports. SFP ports
will always have priority over these 1000BASE-T ports.
The DGS-3627, DGS-3627G, and DGS-3650 contain open slots in the back of the switches that are used to add optional single-
port 10GE modules. Two available slots reside within the DGS-3650, while the DGS-3627 and DGS-3627G both contain three
slots. These modules, the DEM-410CX CX4 and the DEM-410X XFP, are IEEE 802.3ae and IEEE 802.3ak compliant and
support full-duplex mode only. More information will be provided on these modules later in this manual.
The DGS-3600 Switch Series enables a network to use some of the most demanding multimedia and imaging applications
concurrently with other user applications without creating bottlenecks. The built-in console interface can be used to configure the
Switch's settings for priority queuing, VLANs, port trunk groups, port monitoring, and port speed.

NOTE: The SFP combo ports on the Switch cannot be used simultaneously with the corresponding
1000BASE-T ports. If both ports are in use at the same time (ex. port 1 of the SFP and port 1 of the
1000BASE-T), the SFP ports will take priority over the combo ports and render the 1000BASE-T
ports inoperable.

Side Panel
The right-hand side panel of the Switch contains a system fan and ventilation along the entire right side. The left hand panel
includes a system fan and a heat vent. The system fans are used to dissipate heat. Do not block these openings on either side of the
Switch. Leave at least 6 inches of space at the rear and sides of the Switch for proper ventilation. Be reminded that without proper
heat dissipation and air circulation, system components might overheat, which could lead to system failure.

Package Contents
Open the shipping carton of the Switch and carefully unpack its contents. The carton should contain the following items:
•One switch
•One AC power cord
•This manual on CD
•One mounting kit (two brackets and screws)
•Four rubber feet with adhesive backing
•One DCE RS-232 console cable
If any item is missing or damaged, please contact your local D-Link reseller for replacement.
Installation Guidelines
The site where you install the Switch may greatly affect its performance. Please follow these guidelines for setting up the Switch.
•Install the Switch on a sturdy, level surface that can support at least 4.24kg (9.35lbs) of weight for the
DGS-3612/DGS-3612G/DGS-3627/DGS-3627G, or 6.02kg (13.27lbs) for DGS-3650. Do not place heavy objects
on the Switch.
•The power outlet should be within 1.82 meters (6 feet) of the Switch.
•Visually inspect the power cord and see that it is fully secured to the AC/DC power port.
•Make sure that there is proper heat dissipation from and adequate ventilation around the Switch. Leave at least 10
cm (4 inches) of space at the front and rear of the Switch for ventilation.
•Install the Switch in a fairly cool and dry place for the acceptable temperature and humidity operating ranges.
•Install the Switch in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and
direct exposure to sunlight.
•When installing the Switch on a level surface, attach the rubber feet to the bottom of the device. The rubber feet
cushion the Switch, protect the casing from scratches and prevent it from scratching other surfaces.
