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 selection switch (if provided) 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 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 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.
•
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 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. 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 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.

The following manual describes the installation, maintenance and configurations concerning members of the DES-3010F/DES-
3010FL/DES-3010G/DES-3018/DES-3026 Switch group. These 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 primarily to the DES-3018 as the
switch in question for examples, configurations and explanations.
Switch Description
The DES-3010F/DES-3010FL/DES-3010G/DES-3018/DES-3026 is a high performance 8/16/24-port Fast Ethernet switch.
Comprising 10/100Mbps switched unshielded twisted-pair (UTP) and Auto MDI-X/MDI-II convertible ports, and each model
having its own uplink port capability, this Switch will be ideal for segmenting networks into smaller, sub-connected networks for
optimum throughput capability of the most demanding multimedia and imaging applications available on the network without
creating bottlenecks. These ports can also be used for connecting PCs, printers, servers, hubs, routers, switches and other

Ethernet Technology
Fast Ethernet
The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high
performance networks. A number of high-speed LAN technologies are proposed to provide greater bandwidth and improve
client/server response times. Among them, Fast Ethernet, or 100BASE-T, provides a non-disruptive, smooth evolution from
10BASE-T technology.
100Mbps Fast Ethernet is a standard specified by the IEEE 802.3 LAN committee. It is an extension of the 10Mbps Ethernet
standard with the ability to transmit and receive data at 100Mbps, while maintaining the Carrier Sense Multiple Access with
Collision Detection (CSMA/CD) Ethernet protocol.
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 use 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 subnetworks.
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’s and tomorrow's rapidly improving switching and routing internetworking technologies.
Switching Technology
Another key development pushing the limits of Ethernet technology is in the field of switching technology. A switch bridges
Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or Fast Ethernet LAN
segments.
Switching is a cost-effective way of increasing the total network capacity available to users on a local area network. A switch
increases capacity and decreases network loading by making it possible for a local area network to be divided into different
segments, which are not competing with each other for network transmission capacity, and therefore decreasing the load on each
segment.
The Switch acts as a high-speed selective bridge between the individual segments. Traffic that needs to go from one segment to
another (from one port to another) is automatically forwarded by the Switch, without interfering with any other segments (ports).
This allows the total network capacity to be multiplied, while still maintaining the same network cabling and adapter cards.
For Fast Ethernet or Gigabit Ethernet networks, a switch is an effective way of eliminating problems of chaining hubs beyond the
"two-repeater limit." A switch can be used to split parts of the network into different collision domains, for example, making it
possible to expand your Fast Ethernet network beyond the 205-meter network diameter limit for 100BASE-TX networks.
Switches supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for bridging between existing
10Mbps networks and new 100Mbps networks.
Switching LAN technology is a marked improvement over the previous generation of network bridges, which were characterized
by higher latencies. Routers have also been used to segment local area networks, but the cost of a router and the setup and
maintenance required make routers relatively impractical. Today's switches are an ideal solution to most kinds of local area
network congestion problems.
NOTE: For customers interested in D-View, D-Link Corporation's proprietary
SNMP management software, go to the D-Link Website (www.dlink.com) and

DES-3010F/DES-3010FL/DES-3010G/DES-3018/DES-3026 Fast Ethernet Switch Manual
Comprehensive LED indicators display the status of the Switch and the network.
LED or Button Description
Power
This LED will light green after the Switch is powered on to indicate the normal operation
of the Switch’s power supplies. The indicator is dark when the Switch is powered off.
Console
This LED should blink during the Power-On Self Test (POST). When the POST is fin-
ished successfully, the LED goes dark. This indicator will light solid green when the
Switch is being logged into via out-of-band/local console management through the RS-
232 console port in the front of the Switch using a straight-through serial cable.
Link/Act
When the LED mode has been changed to Link/Act, the LEDs will light steady green to
indicate a valid link. A blinking LED indicates activity on the port.
Speed
To the right of every Link/Act LED lies the speed LED, corresponding to every port.
Depending on the switch model, these lights will assume different roles.
DES-3010F/FL/G – A solid green LED indicates the port is transferring data at
100Mbps while a dark, unlit LED will indicate a rate of 10Mbps.
Port 9 – The LED of this port, when lit solid green, indicates a transfer rate of
1000Mbps. When this LED is unlit, it denotes a transfer rate of 10/100Mbps.
Port 10 – For the 3010F and 3010FL, a solid green LED indicates a transfer
rate of 100Mbps and a dark LED indicates no link. For the 3010G, solid green LED
indicates a transfer rate of 1000Mbps and a dark LED indicates no link
DES-3018 / DES-3026 – A solid green LED will indicate a valid link at 100Mbps, and
when blinking, indicates the port is currently transferring data. A solid amber LED will
indicate a valid link at 10Mbps, and when blinking, indicates the port is currently
transferring data.

The DES-3010F/FL/G, DES-3018 or DES-3026 as a Network Backbone
The DES-3018 can be employed as a network backbone for offices or buildings that require many Ethernet connections within a
confined space. Once a high-speed line has been connected from the ISP, the DES-3018 can farm out connections for various end
nodes including PCs, printers, hubs, routers or other switches. The topology configurations are endless but be sure that
connections coming from the DES-3018 are at a equal or slower speed than the ISP uplink to avoid bottlenecking.
The copper ports operate at a speed of 100Mbps or 10Mbps in full or half duplex mode. The 100BASE-FX ports can operate at
100Mbps in full duplex mode only. Copper gigabit ports may operate in 1000Mbps in full-duplex only. SFP gigabit ports operate
in 1000Mbps in full-duplex only.
Connections to the Gigabit Ethernet ports are made using a fiber-optic cable or Category 5e copper cable, depending on the type
of port. A valid connection is indicated when the Link LED is lit.

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 and higher) or Microsoft® Internet Explorer (version
5.0).
SNMP-Based Management
You can manage the Switch with an SNMP-compatible console program. The Switch supports SNMP version 1.0, version 2.0c
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.
Command Line Console Interface through the Serial Port
You can also connect a computer or terminal to the serial console port to access the Switch. The command-line-driven interface
provides complete access to all Switch management features.
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:
15
DES-3010F/DES-3010FL/DES-3010G/DES-3018/DES-3026 Fast Ethernet Switch Manual
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.
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. User names and passwords must first be
created by the administrator. 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-3018 Command Line Interface
Reference Manual on the documentation CD for a list of all commands and additional information on using the CLI.
13. When you have completed your tasks, exit the session with the logout command or close the emulator program.
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 power supply.
Once connected to the console, the screen below will appear on your console screen. This is where the 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.
