Safety Instructions
Use the following safety guidelines to ensure your own personal safety and to help protect your system from potential damage.
Throughout this document, the caution icon ( ) is used to indicate cautions and precautions that you need to review and
follow.
Safety Cautions
To reduce the risk of bodily injury, electrical shock, fire, or 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 tr iangular 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 yo ur trained service provider.
Do not push any objects into the openings of your system. Do ing 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
100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japa n
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 th at is approved for us e 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-wir e cable with prop erly grounded plugs.
Observe extension cable and power strip ratings. Make su re 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.

DES-3028 DES-3028P DES-3028G DES-3052 DES-3052P Layer 2 Fast Ethernet Managed Switch
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 an d safety. Also, refer to the rack installation documentation accompanyin g
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.
xi
DES-3028 DES-3028P DES-3028G DES-3052 DES-3052P Layer 2 Fast 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.

DES-3028/28P/28G/52/52P
The DES-3028, DES-3028P, DES-3028G, DES-3052, and the DES-3052P ar e all members of the D-Link Switch family. These
Switches provide unsurpassed performance, fault tolerance, scalable flexibility, robust security, standard-based interoperability
and impressive technology to future-proof departmental and enterprise network deployments with an easy migration path.
The following manual describes the installation, maintenance, and configurations concerning the DES-3028, DES-3028P, DES3028G, DES-3052, and DES-3052P. These five Switches are identical in configuration 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 use the DES-3028G as the Switch in question for examples,
screen shots, configurations, and explanations.

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.
Web-based Management Interface
After you have successfully installed the Switch, you can configure the Switch, monitor the LED panel, and display statistics
graphically using a web browser, such as Netscape Navigator (version 6.2.3 and higher) or Microsoft® Internet Explorer (version
6.0).
SNMP-Based Management
You can manage the Switch 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.
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, you need the following equipment:
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:
1. Connect the female connector of the RS-232 cable directly to the console port on the Switch, and tighten the captive
retaining screws.
2. 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:
3. Select the appropriate serial port (COM port 1 or COM port 2).
4. Set the data rate to 9600 baud.
5. Set the data format to 8 data bits, 1 stop bit, and no parity.
6. Set flow control to none.
14
DES-3028 DES-3028P DES-3028G DES-3052 DES-3052P Layer 2 Fast Ethernet Managed Switch
7. Under Properties, select VT100 for Emulation mode.
8. Select Terminal keys for Function, Arrow, and Ctrl keys. Ensure that you select Terminal keys (not Windows keys).
NOTE: When you use HyperTerminal with the Microsoft® Windows® 2000 operating system, ensure that you have Windows 2000 Service Pack 2 or later installed. Windows 2000
Service Pack 2 allows you to use arrow keys in HyperTerminal's VT100 emulation. See
www.microsoft.com for information on Windows 2000 service packs.
9. 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.
10. After the boot sequence completes, the console login screen displays.
11. If you have 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 you have previously set up user accounts, log in and continue to configure the Switch.
12. Enter the commands to complete your desired tasks. Many commands require administrator-level access privileges. Read
the next section for more information on setting up user accounts. See the DES-3028/28P/28G/52/52P CLI Manual on
the documentation CD for a list of all commands and additional information on us ing the CLI.
13. When you have completed your tasks, exit the session with the logout command or close the emulator program.
14. Make sure the terminal or PC you are using to make this connection is configured to match these settings.
If you are having problems making this connection on a PC, make sure the emulation is set to VT-100. You will be able to set the
emulation by clicking on the File menu in you HyperTerminal window, 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 powe r s u ppl y .
Once connected to the console, the screen below will appear on your console screen. This is where th e user will enter commands
to perform all the available management functions. The Switch will prompt the user to enter a user name and a password. Upon
the initial connection, there is no user name or password and therefore just press enter twice to access the command line interface.

NOTE: The first user automatically gets Administrator level privileges. It is recommended to
create at least one Admin-level user account for the Switch.
Password Protection
The Switch does not have a default user name and password. One of the first tasks when settings up the Switch is to create user
accounts. Once logged in using a predefined administrator-level user name, users will have privileged access to the Switch's
management software.
After your initial login, define new passwords for both default user names to prevent unauthorized access to the Switch, and
record the passwords for future reference.
