precautions.
•Observe and follow service markings.
oDo not service any product except as explained in your system documentation.
oOpening or removing covers that are marked with the triangular symbol with a lightning bolt may
expose you to electrical shock.
oOnly 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:
oThe power cable, extension cable, or plug is damaged.
oAn object has fallen into the product.
oThe product has been exposed to water.
oThe product has been dropped or damaged.
oThe 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 on the power supply is set to match the power
available at your location:
o115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such
as South Korea and Taiwan
o100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
o230 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.

DES-1228/ME Metro Ethernet Managed Switch Hardware Installation Guide

•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:
oInstall the power supply before connecting the power cable to the power supply.
oUnplug the power cable before removing the power supply.
oIf 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.
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.

SWITCH DESCRIPTION
The DES-1228/ME switch is equipped with unshielded twisted-pair (UTP) cable ports providing dedicated 10 or 100
Mbps bandwidth. The Switch has 24 UTP ports and Auto MDI-X/MDI-II convertible ports that can be used for
linking to another switch. 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 port can support up to 200
Mbps of throughput in full-duplex mode.
In addition, the Switch has two 100/1000 SFP and two 10/100/1000BASE-T/SFP Combo ports. These gigabit combo
ports are ideal for connecting to a server or network backbone.
This stand-alone 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.

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 Firefox, or Microsoft® Internet Explorer (version 6.0 and
above).
SNMP-BASED MANAGEMENT
You can manage the Switch with an SNMP Server. 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
The Switch includes an RJ-45 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 console cable with a male DB-9 connector on one end and an RJ-45 connection on the other. This cable
should be included with the Switch. It establishes the physical connection to the console port.
To connect a terminal to the console port:
Connect the male DB-9 connector on the console cable (shipped with the Switch) to the RS-232 serial port on the
computer running terminal emulation software then insert the RJ-45 connector into the RJ-45 console port on the
front of the Switch.
Set the terminal emulation software as follows:
1. Select the appropriate serial port (COM port 1 or COM port 2).
2. Set the data rate to 9600 baud.
3. Set the data format to 8 data bits, 1 stop bit, and no parity.
4. Set flow control to none.
5. Under Properties, select VT100 for Emulation mode.
6. Select Terminal keys for Function, Arrow, and Ctrl keys. Ensure that you select Terminal keys (not Windows
keys).

7. 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.
8. After the boot sequence completes, the console login screen displays.
9. 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.
10. 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-1228/ME
CLI Reference Guide on the documentation CD for a list of all commands and additional information on
using the CLI.
11. When you have completed your tasks, exit the session with the logout command or close the emulator
program.
12. 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.

FIRST TIME CONNECTING TO THE SWITCH
The Switch supports user-based security that can allow you to prevent unauthorized users from accessing the
Switch or changing its settings. This section tells how to log onto the Switch.
NOTE: The passwords used to access the Switch are case-sensitive; therefore, "S" is not the
same as "s."
When you first connect to the Switch, you will be presented with the first login screen.
NOTE: Press Ctrl+R to refresh the screen. This command can be used at any time to force the
console program in the Switch to refresh the console screen.
Press Enter in both the Username and Password fields. You will be given access to the command prompt DES-
1228/ME:5# shown below:
There is no initial username or password. Leave the Username and Password fields blank.
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.
