· 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 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: o 115 volts (V)/60
hertz (Hz) in most of North and South America and some Far Eastern countries
such as South Korea and Taiwan o 100 V/50 Hz in eastern Japan and 100 V/60 Hz
in western Japan o 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 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.

Ge ne ra l Pre c a ut ions for Ra c k -M ount a ble Produc t s
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 uncertain that suitable
grounding is available.
vi
xStack® DGS-3420 Series Layer 2+ Managed Stackable Gigabit Switch Hardware
Installation Reference Guide 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.

Description
This LED will light green after powering the Switch on to indicate the ready
state of the device. The indicator is dark when the Switch is no longer
receiving power (i.e. powered off).
This LED will blink green during the Power-On Self Test (POST). When the POST
is finished, the LED goes dark. The indicator will light steady green when a
user is logged in through the console port.
This LED will light green if the Redundant Powers Supply is in use. If the
indicator is off, the RPS is not in use. When the switch detects that the RPS
is connected, the light will be blinking.
This LED will light green if a Secure Digital (SD) card is plugged in. When
the Switch is reading or writing, the indicator will blink green. No light LED
means there is no link. A solid red LED indicates SD card failure.
For standalone Switches, this will display number “1”. For stacked Switches,
this indicates the position in the stacking box ID. The box ID is assigned
either by the user (static mode) or by the system (automatic mode). When “1”
to “12” is displayed, this indicates the stacking position of the switch. An
“H” indicates the device was assigned as the stacking Master. “h” means the
device was selected to be the Backup Master. A “G” is displayed when the
Safeguard Engine feature enters the exhausted mode.
The Switch has LED indicators for Link and Activity. The LED will light steady
green when there is a secure connection (or link) to a 1000Mbps Ethernet
device at any of the ports, or steady orange when there is a secure connection
(or link) to a 10/100Mbps Ethernet device at any of the ports. The LED will
blink green when a 1000Mbps port is active, or blink orange when a 10/100Mbps
port is active. The LED remains dark when there is no link or activity.
Only the DGS-3420-28PC and the DGS-3420-52P switches are equipt with a PoE
LED. When this light is on with a solid green light, it means that the
corresponding ports are feeding power to the PoE devices plugged in. When this
light is on with a solid orange light, it means that the port is in an error
condition state. When this light is off, it means that the ports are not
supplying power to the devices plugged into the ports.

IP Addresses SNMP Settings
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 successfully installing the Switch, the
user can configure the Switch, monitor the LED panel, and display statistics
graphically using a Web browser, such as Microsoft® Internet Explorer (version
5.5 and later), Netscape (version 8 and later), Mozilla Firefox (version 2.0
and later), Safari (version 4.0 and later), and Google Chrome (version 6.0 and
later).
SNMP-Based Management The Switch is also managed with an SNMP-compatible
console program. It supports SNMP version 1.0, 2.0 and 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 Interface Management through the Serial Port or remote Telnet The
user can also connect a computer or terminal to the serial console port to
access the DGS-3420 range. The command line interface provides complete access
to all DGS-3420 Series of switches management features.
Connecting the Console Port
The console port on the front panel of the Switch is used to connect a
computer that monitors and configures the switch. The console port is an RJ-45
port and requires a special cable that is included with the switch, to
establish the physical connection.
To use the console port, the following equipment is needed: · A terminal or a
computer with both an RS-232 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 any of the
DGS-3420 Series. 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 DGS-3420-28SC for example) 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:
· 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.
29
xStack® DGS-3420 Series Layer 2+ Managed Stackable Gigabit Switch Hardware
Installation Reference Guide
· 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 the 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 socket on the back of the DGS3420 Series 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 DGS-3420 Series CLI Reference
Guide 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 you experience problems while making a connection, make sure the emulation
is set to VT-100. The emulation settings can be configured by:
1. Click File Menu in HyperTerminal
2. Click Properties from the drop-down menu 3. Click 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 following image appears. 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 password. Logging on at the beginning requires no username or password. Just press the Enter key twice to access the command line interface.

NOTE: The first user automatically gets Administrator level privileges. At least one Admin-level user account must be created for the Switch.
Connecting to the Management Port
The front panel of the Switch features an out-of-band RJ-45 Management port
which can easily connect to a notebook. Connect to the out-of-bound management
console using a web browser or Telnet command prompt interface. This is the
default login interface, and is the tool you can use when connecting to the
Switch for the first time.
To use the Management port, connect one end of an Ethernet cable to a computer
and the other to the switch. The default IP address of the Management port is
192.168.0.1, and a subnet mask of 255.255.255.0. Make sure that the computer
being used for Switch management has a nonconflicting IP address in the
192.168.0.x subnet.
The IP settings or enabled status of the Management port can be changed
through the console port, or through the webbased Switch management interface.
To change the configuration of the Management port, use the command:
config out_band_ipif {ipaddress
To view the status or IP settings, use the command: show out_band_ipif

Passw ord Protection
The DGS-3420 Series Switches do not have a default user name and password. One
of the first tasks when settings up the Switch is to create user accounts.
Logging in using a predefined administrator-level user name will give the user
privileged access to the Switch’s management software.
After the initial login, define new passwords for both default user names to
prevent unauthorized access to the Switch, and record the passwords for future
reference.
To create an administrator-level account for the Switch, do the following: 1.
At the CLI login prompt, enter create account admin followed by the
NOTE: Passwords are case sensitive. User names and passwords can be up to 15
characters in length.
The sample below illustrates a successful creation of a new administrator- level account with the user name “newmanager”.

Enter a case-sensitive new password: Enter the new password again for confirmation: Success.
DGS-3420-28SC:admin#
Figure 43 Create account command
NOTICE: CLI configuration commands only modify the running configuration file and are not saved when the Switch is rebooted. To save all your configuration changes in nonvolatile storage, you must use the save command to copy the running configuration file to the startup configuration.
Assigning IP Addresses
Each Switch must be assigned its own IP Address, which is used for
communication with an SNMP network manager or other TCP/IP application (for
example BOOTP, TFTP). The Switch’s default IP address is 10.90.90.90. You can
change the default Switch IP address to meet the specification of your
networking address scheme.
The Switch is also assigned a unique MAC address by the factory. This MAC
address cannot be changed, and can be found by entering the command show
switch into the command line interface, as shown below.

The Switch’s MAC address can also be found from the Web management program on the System Information window in the Configuration folder.
The IP address for the Switch must be set before it can be managed with the Web-based manager. The Switch IP address can be automatically set using BOOTP or DHCP protocols, in which case the actual address assigned to the Switch must be known.
The IP address may be set using the Command Line Interface (CLI) over the
console serial port as follows: Starting at the command line prompt, enter the
commands
config ipif System ipaddress xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy
Where the x’s represent the IP address to be assigned to the IP interface named System and the y’s represent the corresponding subnet mask.
Alternatively, you can enter config ipif System ipaddress xxx.xxx.xxx.xxx/z. Where the x’s represent the IP address to be assigned to the IP interface named System and the z represents the corresponding number of subnets in CIDR notation.

SNMP Settings
Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application
Layer) 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 SNMP agent. SNMP
defines both the format of the MIB specifications and the protocol used to
access this information over the network.
The Switch supports SNMP versions 1, 2c, and 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 SNMP v1 and v2, 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 SNMP v1 and v2
management access are: · public – Allows authorized management stations to
retrieve MIB objects. · private – Allows authorized management stations to
retrieve and modify MIB objects.
SNMP v3 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 can 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 SNMP v1 while assigning a higher level of
security to another group, granting read/write privileges using SNMP v3.
Using SNMP v3 individual users or groups of SNMP managers can be allowed to
perform or be restricted from performing specific SNMP management functions.
The functions allowed or restricted are defined using the Object Identifier
(OID) associated with a specific MIB. An additional layer of security is
available for SNMP v3 in that SNMP messages may be encrypted. To read more
about how to configure SNMP v3 settings for the Switch read the section
entitled Management.

Traps
Traps are messages that alert network personnel 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 the trap recipient (or network manager).
Typical traps include trap messages for Authentication Failure, Topology
Change and BroadcastMulticast Storm.
Management Information Base (MIB)
The Switch in the 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-only or read-write.
