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.
•
•
•
•
•
•
•
•
•
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.
xiv

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

xStack DGS-3600 Series
The DGS-3600 switch 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 10 Gigabit technology to future-
proof departmental and enterprise network deployments with an easy migration path.
The following manual describes the installation, maintenance and configurations concerning members of the D-Link DGS-3600
switch series, including the DGS-3612G, DGS-3627, DGS-3627G, and the DGS-3650. These four switches are identical in
configurations and very similar in basic hardware and consequentially, most of the information in this manual will be universal to
the total group of Switches. 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. For the remainder of this document, we will refer to the DGS-
3600 as the switch in question for examples, configurations and explanations.
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 Ether-
net 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, 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-3612GG
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.
1

xStack DGS-3600 Series Layer 3 Stackable Fast Ethernet Managed Switch
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 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-310GT (1000BASE-LX), DEM-311GT (1000BASE-SX), DEM-
312GT2 (1000BASE-SX), DEM-314GT (1000BASE-LH), 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 which means that 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.
Each switch also contains open slots in the rear of the Switch, which 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.
This Switch enables the 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, and port trunk groups, port monitoring, and port speed.
