Switch to an End Node
An end node is a generic name for edge networking devices that will be connected to this switch. Typical examples of
end nodes are Personal Computers (PCs), Notebooks, Access Points, Print Servers, VoIP Phones and more. Each
end node should be fitted with a 100/1000/10000 Mbps RJ45 networking port. Normally, end nodes will connect to this
switch by using a standard twisted-pair UTP/STP network cable. When a successful connection is established, the
corresponding port light will illuminate and blink to indicate that network activity is taking place on that port.
The diagram below displays a typical end node connected to the S witc h.
Figure 3-1 Connecting the Switch to an End Node
Switch to Another Switch
The Switch can be used to connect to any other switch or hub in the network. This network topology is us ed when t he
Switch does not have enough ports to cater for all the end nodes in the network.
There is a great deal of flexibility on how connections are made using the appropriate cabling.
• Connect a 10BASE-T switch port to the Switch using a twisted-pair Category 3, 4, or 5 UTP/STP cable.

Management Options
This switch provides multiple access platforms that can be used to configure, manage, and monitor networking
features available on this switch. Currently there are three management platforms available which are described
below.
Command Line Interface (CLI)
This switch can be managed, out-of-band, by using the console port on the front panel of the S witc h. Alt ernative ly, the
Switch can also be managed, in-band, by using a Telnet connection to any of the LAN ports on the Switch. The
command line interface provides the access to some of switch management features.
For more detailed information about the CLI, refer to the DGS-1250 Series CLI Reference Guide.
SNMP-based Management
The Switch can be managed with an SNMP-compatible console program. The Switch supports SNMP v1, SNMPv2c
and SNMPv3. 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.
Web User Interface (Web UI)
The Web UI can be accessed from any computer running web browsing software from its LAN port when it is
connected to any of the RJ45 or SFP/SFP+ ports. The Web UI on the Switch can also be accessed using an HTTPS
(SSL) connection.
This management interface is a more graphical representation of the features that can be viewed and configured on
this Switch. Most of the features available through the CLI can be acc essed through the Web UI. Web browsers like
Microsoft’s Internet Explorer, Mozilla Firefox, Google C hr ome, or Safari can be used.
For more detailed information about the Web UI, refer to the DGS-1250 Series Web UI Reference Guide.
Connecting to the Console Port
The front panel of the Switch provides an RJ45 console port to connect a remote system for monitoring and
configuring the Switch.
To use the console port, the following equipment is needed:
• A terminal or a computer with both an RS-232 serial port and terminal emulation software.
• A console cable with a male DB9 connector on one end and an RJ45 connection on the other. This cable
should be included with the Switch. It establishes the physical connection to the console port.
To connect the RJ45 console port on the Switch to the computer:
• Connect the male DB9 connector on the console cable (shipped with t he Sw itch) to the RS-232 serial port on
the computer running terminal emulation software then insert the RJ45 connector into the RJ45 console port
on the front of the S witc h.
To configure the terminal emulation software as follows:
• Select the appropriate serial port (COM1 or COM2).
• 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.

To be able to view the boot procedure, the Switch needs to be rebooted. The simplest way, at this stage, to reboot the
Switch is to unplug and re-insert the power cable from and into the power receptacle on the back of the Switch.
After correctly configuring the terminal settings and re-inserting the power cable, the boot procedure will appear in the
terminal.

User Access Verification
Username:admin
Password:*****
NOTE: For security reasons, it is highly recommended to configure a personal username and
password for this Switch.
Creating a User Account
One of the first and most important tasks will be to create user accounts. Logging in using a predefined administrator-
level username will give the user privileged access to the Switch's management software. Also this will prevent
unauthorized access to t he S witch and record the passwords for future reference.
An example to create an administrator-level account for the Switch c alled ‘Ne wU ser’:
Switch#configure terminal
Switch(config)#username NewUser password 12345
Switch(config)#end
Switch#
In the example above:
1. At the CLI command prompt, enter the configure terminal command to enter the Global Configuration
Mode. Press ENTER.
2. Enter the username NewUser password 12345command. Press ENTER. This will create a user account
with the username of NewUser and a password of 12345.
3. Enter the end command to exit back to the EXEC Mode.
NOTE: Passwords are case sensitive. Usernames can be up to 32 characters in length.
Passwords can be up to 32 plain-text characters in length.
Configuri ng the IP Address
Each switch must be assigned its own in-band IP Address, which is used for communication with an SNMP network
manager or other TCP/IP applications. The Switch's default IP address is 10.90.90.90 with a subnet mask of
255.0.0.0.You can change the IP address of the Switch to meet the specification of your networking address scheme.
The IP address of the Switc h must be configured before it can be managed, by the user, via the Web UI.
An example to change the IP address of the Switc h to ‘ 10.50.50.50’, using a subnet mask of ‘255.0.0.0’:
Switch#configure terminal
Switch(config)#interface vlan 1
Switch(config-if)#ip address 10.50.50.50 255.0.0.0
Switch(config-if)#
In the above example,
DGS-1250 Series Gigabit Ethernet Smart Managed Switch Hardware Installation Guide
24
1. We entered the Global Configuration Mode by entering the configure terminal command.
2. Then we entered the VLAN Configuration Mode of the default VLAN, which is VLAN 1, by entering the
interface vlan 1 command.
3. Then we changed the IP address of the Switch to 10.50.50.50 and the subnet mask to 255.0.0.0 by entering
the ip addre ss 10.50.50.50 255.0.0.0 command.
The Switch can now be accessed and configured through Telnet or the Web UI. The Switch’s IP address can also
autom atical l y be obtained b y using t he DHCP protocol.
Connecting using SNMP
The Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) protocol designed
specifically for managing and monitoring network devices. SNMP enables network management stations to read and
modify the settings of gateways, routers, switches, and other network devices. Use SNMP to configure system
features for proper operation, monitor performance, and detect potential problems in the Switch, switch group, or
network.
Managed devices that support SNMP include software (referred to as an agent), which runs locally on the device. A
defined set of variables (managed objects) is maintained by the SNMP agent and used to manage the device. These
objects are defined in a Management Information Base (MIB), which provides a standard presentation of the
information controlled by the on-board SNM P age nt. S NMP def ines bot h the form at of the MIB specif ications and the
protocol used to access this information over the network.
The Switch supports SNMPv1, SMNPv2c, a nd SN MP v 3. The administrator may specify which SNMP version to use to
monitor and control the Switch. The three SNMP versions vary in the level of security provided between the
management station and the network device.
In SNMPv1 and SNMPv2c, user authentication is accomplished using 'community strings', which function like
passwords. The remote user SNMP application and the Switch SNMP must use the same community string. SNMP
packets from any station that has not been authenticated are ignored (dropped).
The default community strings for the Switch used for SNMPv1 and SNMPv2c management access are:
• public - Allows authorized management stations to retrieve MIB objects.
• private - Allows authorized management stations to retrieve and modify MIB objects.
SNMPv3 uses a more sophisticated authentication process that is separated into two parts. The first part is to
maintain a list of users and their attributes that are allowed to act as SNMP managers. The second part describes
what each user on that list c an do as an SNMP manager.
The Switch allows groups of users to be listed and configured with a shared set of privileges. The SNMP version may
also be set for a listed group of SNMP managers. Thus, a group of SNMP managers can be created to view read-only
information or receive traps using SNMPv1 while assigning a higher level of security to another group, granting
read/wri te priv ileges us ing SN M Pv3.
Using SNMPv3 individual users or groups of SNMP managers can be allowed to perform or be restricted from
performing specific SNMP management functions. The functions that have been allowed or restricted are defined
using the Object Identifier (OID) associated with a specific MIB. An additional layer of security is available for SNMPv3
in that SNMP messages may be encrypted.
Traps
Traps are messages that are sent by an SNMP-enabled device to the NMS, and can be used to alert network
personn el of events that occur on the Switch. The events can be as serious as a reboot (someone accidentally turned
off the Switch), or less serious like a port status change. The Switch generates traps and sends them to a pre-
configured IP address, usually an NMS. Typical traps include trap messages for Authentication Failure and Topology
Change.
DGS-1250 Series Gigabit Ethernet Smart Managed Switch Hardware Installation Guide
25
Management Information Base (MIB)
A Management Information Base (MIB) stores management and counter information. The Switch uses the standard
MIB-II Management Information Base module. Consequently, values for MIB objects can be retrieved from any
SNMP-based network management software. In addition to the standard MIB-II, the Switch also supports its own
proprietary enterprise MIB as an extended Management Information Base. The proprietary MIB may also be retrieved
by specifying the MIB Object Identifier. MIB values can be either read-o nly o r read-write.

General Precautions for Rack-Mountable Products
Please pay careful attention to the following precautions concerning rack stability and safety. Systems are considered
to be components in a rack. Thus, a 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.
ATTENTION : Le montage de systèmes sur un rack dépourvu de pieds stabilisateurs avant et
latéraux peut faire basculer le rack, pouvant causer des dommages corporels dans certains cas. Par
conséquent, installez toujours les pieds stabilisateurs avant de monter des composants sur le rack.
Après l'installation d'un système ou de composants dans un rack, ne sortez jamais plus d'un
composant à la fois hors du rack sur ses glissières. Le poids de plusieurs composants sur les
glissières en extension peut faire basculer le rack, pouvant causer de graves dommages corporels.
DGS-1250 Series Gigabit Ethernet Smart Managed Switch Hardware Installation Guide
40
• 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.
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.
ATTENTION : Ne neutralisez jamais le conducteur de masse et ne faites jamais fonctionner le
matériel en l'absence de conducteur de masse dûment installé. Contactez l'organisme de contrôle
en électricité approprié ou un électricien qualifié si vous n'êtes pas sûr qu'un système de mise à la
masse adéquat soit disponible.
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.
ATTENTION : La carcasse du système doit être positivement reliée à la masse du cadre du rack.
N'essayez pas de mettre le système sous tension si les câbles de mise à la masse ne sont pas
raccordés. Le câblage de l'alimentation et de la mise à la masse de sécurité doit être inspecté par un
inspecteur qualifié en électricité. Un risque électrique existe si le câble de mise à la masse de
sécurité est omis ou débranché.
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):
• 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.
• When transporting a sensitive component, first place it in an antistatic container or packaging.
• Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads, workbench pads
and an antistatic grounding strap.
