•
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 ACpowered 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.
ix
xStack DGS-3400 Series Fast Ethernet Switch
•
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.
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.
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.
•
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.
x
xStack DGS-3400 Series Fast Ethernet Switch
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.

xStack DGS-3400 Series Fast Ethernet Switch
Section 1
The DGS-3400 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 future-proof 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-3400
Switch Series. These switches include: the DGS-3426, DGS-3427 and the DGS-3450. The DGS-3400 Series 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-3400 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.
Switch Description
D-Link's next-generation xStack DGS-3400 series switches are high port-density stackable switches that combine the
ultimate performance with fault tolerance, security, management functions with flexibility and ease-of-use. All these
features, typically found in the more expensive chassis-based solutions, are available from the xStack DGS-3400 switch
series at the price of a stackable switch!
All xStack DGS-3400 Series switches have some combination of 1000BASE-T ports, SFP ports and 10-Gigabit ports that
may be used in uplinking various network devices to the Switch, including PCs, hubs and other switches to provide a
gigabit Ethernet uplink in full-duplex mode. The SFP (Small Form Factor Portable) combo ports are used with fiber-optical
transceiver cabling in order to uplink various other networking devices for a gigabit link that may span great distances.
These SFP ports support full-duplex transmissions, have auto-negotiation and can be used with DEM-310GT (1000BASELX), DEM-311GT (1000BASE-SX), DEM-314GT (1000BASE-LH) and DEM-315GT (1000BASE-ZX) transceivers. The
rear panel of the DGS-3400 Series Switches include spaces for optional single-port module inserts for single port 10GE
XFP or 10GBASE-CX4 modules used for backbone uplink or STACKING connection to another xStack DGS-3400 Series
Switch.

This LED will light when the internal power has failed and the RPS has taken over
the power supply to the Switch. Otherwise, it will remain dark.
One row of LEDs for each port is located above the ports on the front panel. The
indicator above the left side of a port corresponds to the port below the indicator
in the upper row of ports. The indicator above the right side of a port corresponds
to the port below the indicator in the lower row of ports. A steady green light
denotes a valid 1000Mbps link on the port while a blinking green light indicates
activity on the port (at 1000Mbps). A steady orange light denotes a valid 10 or
100Mbps link on the port while a blinking orange light indicates activity on the port
(at 100Mbps). These LEDs will remain dark if there is no link/activity on the port.
A steady green light denotes a valid link on the port while a blinking green light
indicates activity on the port. These LEDs will remain dark if there is no
link/activity on the port.
LED indicators for the Combo ports are located above the ports and numbered
1 – 4 for Comb 1, Combo 2, etc. ports. A steady green light denotes a valid link
on the port while a blinking green light indicates activity on the port. These LEDs
will remain dark if there is no link/activity on the port.
These two seven segment LEDs display the current switch stack order of the
Switch while in use.

The Optional Module
The rear panel of the DGS-3426, DGS-3427 and DGS-3450 include open slots that may be equipped with the DEM-410X
1-port 10GE XFP uplink module, or a DEM-410CX 1-port 10GBASE-CX4 uplink module, both sold separately.
Adding the DEM-410X optional module will allow the administrator to transmit data at a rate of ten gigabits a second. The
module port(s) are compliant with standard IEEE 802.3ae, support full-duplex transmissions only and must be used with
XFP MSA compliant transceivers.
The DEM-410CX uses copper wire medium, not optic fiber and therefore has a transmit length limit up to 1 meters.
Compliant with the IEEE802.3ak standard, this module uses a 4-laned copper connector for data transfer in full-duplex
mode.
To install these modules in the DGS-3400 Series Switch, follow the simple steps listed below.
CAUTION: Before adding the optional module, make sure to disconnect all power sources
connected to the Switch. Failure to do so may result in an electrical shock, which may cause
damage, not only to the individual but to the Switch as well.
At the back of the Switch to the left is the slot for the optional module. This slot must be covered with the faceplate if the
slot is not being used. If a module will be installed in an available slot, the faceplate is easily removed by loosening the
screws and pulling off the plate.
The front panels of the available modules are shown here:

Management Options
This system may be managed out-of-band through the console port on the front panel or in-band using Telnet. The user
may also choose the web-based management, accessible through a web browser.
1. Web-based Management Interface
After successfully installing the Switch, the user can configure the Switch, monitor the LED panel, and display
statistics graphically using a web browser, such as Netscape Navigator (version 6.2 and higher) or Microsoft®
Internet Explorer (version 5.0).
2. SNMP-Based Management
The Switch can be managed with an SNMP-compatible console program. The Switch supports SNMP version 1.0,
version 2.0 and version 3.0. The SNMP agent decodes the incoming SNMP messages and responds to requests
with MIB objects stored in the database. The SNMP agent updates the MIB objects to generate statistics and
counters.
3. Command Line Console Interface through the Serial Port
The user can also connect a computer or terminal to the serial console port to access the Switch. The commandline-driven interface provides complete access to all Switch management features.
18
xStack DGS-3400 Series Fast Ethernet Switch
Connecting the Console Port (RS-232 DCE)
The Switch provides an RS-232 serial port that enables a connection to a computer or terminal for monitoring and
configuring the Switch. This port is a female DB-9 connector, implemented as a data terminal equipment (DTE)
connection.
To use the console port, the following equipment is needed:
•
A terminal or a computer with both a serial port and the ability to emulate a terminal.
•
A null modem or crossover RS-232 cable with a female DB-9 connector for the console port on the Switch.
To connect a terminal to the console port:
Connect the female connector of the RS-232 cable directly to the console port on the Switch, and tighten the captive
retaining screws.
Connect the other end of the cable to a terminal or to the serial connector of a computer running terminal emulation
software. Set the terminal emulation software as follows:
•
Select the appropriate serial port (COM port 1 or COM port 2).
•
Set the data rate to 115200 baud.
•
Set the data format to 8 data bits, 1 stop bit, and no parity.
•
Set flow control to none.
•
Under Properties, select VT100 for Emulation mode.
•
Select Terminal keys for Function, Arrow and Ctrl keys. Make sure to use Terminal keys (not Windows keys) are
selected.
NOTE: When using HyperTerminal with the Microsoft® Windows® 2000 operating system, ensure
that Windows 2000 Service Pack 2 or later is installed. Windows 2000 Service Pack 2 allows use
of arrow keys in HyperTerminal's VT100 emulation. See www.microsoft.com for information on
Windows 2000 service packs.
•
After you have correctly set up the terminal, plug the power cable into the power receptacle on the back of the Switch.
The boot sequence appears in the terminal.
•
After the boot sequence completes, the console login screen displays.
•
If the user has not logged into the command line interface (CLI) program, press the Enter key at the User name and
password prompts. There is no default user name and password for the Switch. The administrator must first create user
names and passwords. If user accounts have been previously set up, log in and continue to configure the Switch.
•
Enter the commands to complete desired tasks. Many commands require administrator-level access privileges. Read
the next section for more information on setting up user accounts. See the xStack DGS-3400 series CLI Manual on
the documentation CD for a list of all commands and additional information on using the CLI.
•
To end a management session, use the logout command or close the emulator program.
If problems occur in making this connection on a PC, make sure the emulation is set to VT-100. The emulation settings can
be configured by clicking on the File menu in the HyperTerminal window by clicking on Properties in the drop-down
menu, and then clicking the Settings tab. This is where you will find the Emulation options. If you still do not see
anything, try rebooting the Switch by disconnecting its power supply.
