Safety Instructions

Use the following safety guidelines to e nsure your own personal safety and to help pr otect your system from potential damage.
Throughout this safety section, the ca ution icon (

) is used to indicate cautions and precautions that need to be reviewed and

followed.

Safety Cautions

To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment observe the following precautions:

• Observe and follow service markings.

• Do not service any product except as explained in the system documentation.

• Opening or r emoving co vers that ar e marked with the tri angular symb ol with a l ightning bolt may exp ose the us er 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:

• Damage to the power cable, extension cable, or plug.

• An object has fallen into the prod uct.

• The product has been exposed to water.

• The product has been dropped or damaged.

• The product does not operate correctly when the operating instructions are correctly followed.

• Keep your system away from radiators and heat sources. Also, do not block cooling vents.

• Do not spill food or liquids on system components, and never operate the product in a wet environment. If the system gets

wet, see the appropriate section in the troubleshooting guide or contact your trained service provider.

• Do not push a ny objects int o the openin gs of the syste m. Doing so ca n cause fire or electric shock by shor ting out inte rior

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 unsure of the type

of power source required, consult your service provider or local power company.

• To help avoid damaging the system, be sure t he voltage s election switch (if p rovided) on the po wer supply is set to match the

power available at the Switch’ s lo c a tion:

• 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.

vi

xStack® DGS-3400 Series L a yer 2 Gig abit Ethernet Managed Switch

• 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 exte ns ion 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.

• To help protect the 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/natio nal 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.

• 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 jo ined multiple
racks befor e working on the rack.

CAUTION: Installing s yste ms in a rack without t he f ront and s ide sta bilizers insta lled c ould
cause the rack to t ip o ver , pote nti al l y resul tin g in bo di l y inj ury under certain c irc u m s tances .
Therefore, always install the stabilizers before installing components in the rack. After
installing s ystem/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.

• Always load the rack from the bo ttom 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 co mponent into or out of a rack; the slid e rails

can pinch your finge r s.

• After a component is inserted into the rack, car efully extend the rail into a locking position, and then slid e 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.

vii

xStack® DGS-3400 Series L a yer 2 Gig abit Ethernet Managed Switch

cable is omitted or

• 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 ope rate the equipm ent 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.

CAUTION: The s ystem chassis m ust be positively grounded to the rack cabinet f rame.
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
disconnected.

Lithium Batter y Precauti on

CAUTION: Incorrectl y repla cing th e lithium batter y of the Sw itch m ay cause the b atter y to

explode. Replace this batter y only with the sam e or equi valent type r ecomm ended by the
manufacturer. Discard used batteries according to the manufacturer instructions.

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 unpack ing a static-sensitive component from its shipping carton, do not remove the component from the antistatic

packing material until read y to install the component in the system. Just before un wrapping the antistatic packa ging, be
sure to discharge static electricity from your bod y.

2. When transporting a sensitive component, first place it in an antistatic container or packaging.

3. Handle all sensitive compone nts in a static-safe area. If possible, use antistatic floor pads, workbench pads and an

antistatic grounding str a p.

The Optional Module

The rear panel of the DGS-3426, DGS-3426P, DGS-3427 and DGS-3450 include open slots that may be equipped with the DEM­410X 1-port 10GE XFP stacking uplink module, or a DEM-410CX 1-port 10GBASE-CX4 stacking uplink module, both sold
separately. These mod ul es may be use d to stack switches in a switch stack using a Duplex Ring or Duplex Chain topology.

Adding the DEM-410X optional module will allow the administrator to transmit data at a rate of ten gigabits a second. The
module port(s) are compliant with standard IEEE 802.3ae, support full-duplex tra nsmissions only and must be used with XFP
MSA compliant transceivers.

The DEM-410CX uses copper wire medium, not optic fiber and therefore has a transmit length limit up to 1 meter. Co mpliant
with the IEEE802.3ak standard, this module uses a 4-laned copper connector for data transfer in full-duplex mode within a
stacking configuration.

To install t hese modules in the DGS-3400 Series, follow the si mple ste ps listed below.

CAUTION: Before adding the optional module, make sure to disconnect all power sources
connected to the Switch. Failure to do so may result in an electrical shock, which may cause
damage, not only to the individual but to the Switch as wel l.

At the back of the Switch to the left is the slot for the op tional module. This slot must be covered with the faceplate if the slot is
not being used. If a module will be installe d in an available slot, the faceplate is easily removed by loosening the screws and
pulling off the plate.

The front panels of the available modules are shown here:

Management Options

This system ma y be managed out-of-band through the console port on the front panel or in-band usin g Telne t. T he user may also
choose the web-based management, accessible through a web browser.

1. Web-based Management Interface

After successfully installing the Switch, the user can configure the Switch, monitor the LED pa nel, and display stati stics
graphically using a web browser, such as Netscape Navigator (version 6.2 and higher) or Microsoft® Internet Explorer
(version 5. 0 and higher).

2. SNMP-Based Management

The Switch can be managed 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.

3. Command Line Console Interface through the Serial Port

The user can also connect a computer or terminal to the serial console port to access the Switch. The command-line­driven 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, the following equipment is needed:

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 conso le port:

Connect the female connector of the RS-232 cable directly to the console port on the Switch, and tighten the captive retaining
screws.

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 a s 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.
Select Terminal ke ys fo r 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 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 receptacle on the back of the 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 xStack
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 c lose the emu la tor program.

If problems occur in making this connection on a PC, make sure the emulation is set to VT-100. The emulation settings can be
configured by clicking o n the File menu in the Hyper Terminal wind ow by clicki ng on Properties in the d rop-down me nu, and
then clicki ng 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.

There is no initial username or pass word. Leave the Username and Password fields blank.

NOTE: The first user automatically gets Administrator level privileges. At least one Admin-level
user account must be created for the Switch.

Password Protection

The xStack® DGS-3400 Series 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 initi al lo gin, de fine ne w pa ss words for bot h defa ul t user na mes to pr eve nt una ut hori zed acce ss to the S witc h, and rec ord
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 <user name> and press the Enter key.

2. The Switch will then prompt the user to provide a password. Type the <password> used for the administrator

account being created and press the Enter key.

3. Once entered, the Switch will again ask the user to enter the same password again to verify it. Type the same

password and press the Enter key.

4. A “Success” response by the Switch will verify the creation of the new administrator.

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".

SNMP Settings

Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically for managing and
monitoring network device s. SNMP enab les network mana gement statio ns to read and modi fy the settings o f gateways, ro uters,
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 xStack
to monitor a nd control the Switch. The three ve rsions of SNMP var y in the level o f securit y provided be tween the ma nagement
station and the network device.

In SNMP v.1 and v.2, user authentication is accomplished using 'community string s', whi ch func tion like pass words. 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 v.1 and v.2 management acc ess are:

public – Allows authorized management stations to retrieve MI B objects.

DGS-3400 Series support SNMP versions 1, 2c, and 3. The administrator may specify which version of SNMP to us e

private – Allows authorized management stations to retrieve and modify MIB objects.

SNMP v.3 uses a more sophisticated authentication process that is sepa rated into two parts. T he first part is to mainta in 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 allo ws 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 S NMP v.1 while assigni ng a higher l evel of secu rity to another group, granting read/write privileges using SNMP v.3.

Using SNMP v.3 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 v.3 in that SNMP messages may be
encrypted. To read more about how to configure SNMP v.3 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 po rt status change . The Switch genera tes traps and se nds
them to the tr ap r ec ip ie nt ( o r net work ma na ge r) . Typical trap s i ncl ud e tr ap me ssa ge s fo r Aut he nti cation Fail ure , T o po lo gy C hange
and Broadcast\Multicast Storm.

MIBs

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 SNMP­based network management software. In addition to the standard MIB-II, the Switch also supports its own prop rietary 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.

IP Address Assignment

An IP Address must be assigned to each switch, 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. The user may change the default
Switch IP address to meet the specification of your networking address s cheme.

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 also appears in Sw itch Info rma tion menu of the web-based management interface. The IP address for
the Switch must be set before it can be managed with the Web-based or SNMP manager, Telnet or SSH. 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 command:

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 mas k. Alternati vely, the user can enter c onfig ipif System ipa ddress 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. The IP interface named System on the Switch can be assigned an IP address and subnet mask, which can then be used to
connect a management station to the Switch's Telnet or Web-based management agent.

Figure 4 - 5 Assigning the Switch an IP Address

In the above example, the Switch was assigned an IP address of 10.53.13.26 with a subnet mask of 255.0.0.0. The system message
Success indicates that the com mand was executed successfully. The Switch can now be configured and managed via Telnet and
the CLI or via the Web-based manageme nt .

NOTE: The DGS-3400 Series have the c apability to b e configured for an IP address of 0.0.0.0, or,
in essence, have no IP address. This function maybe used to disable Layer 3 functions of the
Switch. When the IP addre ss is set to 0.0.0.0 (inval id IP addres s), the Switc h can onl y be managed
through the conso le port or SIM. Other m anagement applicat ions such as Telnet, W eb-based and

All software functions of the xStack® DGS-3400 Series can be managed, configured and monitored via the embedded web-based
(HTML) interface. Manage the Switch from remote stations anywhere on the network through a standard browser. The browser
acts as a universal access tool and can communicate directly with the Switch using the HTTP protocol.

The Web-based management module and the Console program (and Telnet) are different ways to access the same internal
switching so ftware and configur e it. Thus, al l settings e ncountere d in web-based management are the same as those found in the
console program.

designed to carry a complete range of user traffic, including voice, data and video signals.
auto-negotiation: A feature on a port which allows it to advertise its capabilities for speed, duplex and flow control. When

connected to an end station that also supports auto-negotiation, the link can self-detect its optimum oper a ting setup.
backbone port: A port which does not learn device addresses, and which receives all frames with an unknown address. Backbone

ports are normally used to connect the Switch to the backbone of your network. Note that backbone ports were formerly known as
designated downlink ports.

backbone: The part of a network used as the primary path for transporting traffic between network segments.
bandwidth: Information capacity, measured in bits per second, that a channel can transmit. The bandwidth of Ethernet is 10Mb p s,

the bandwidth of Fast Ethernet is 100Mbps.

baud rate: The switching sp eed o f a line. Also known as line speed between network segments.
BOOTP: The BOOTP protocol allows automatic mapping of an IP address to a given MAC address each time a device is started.

In additio n, the proto col can assi gn the subnet mask and d efault gate way to a device.
bridge: A device that inter connects local or re mote networks no matter what higher leve l protocols are involved. Bridges form a

single logical network, centraliz ing network administration.

broadcast: A message sent to all destination devices on the network.
broadcast storm: Multiple simultaneous broadcasts that typically absorb available network bandwidth and can cause network

failure.

computers to the serial form used o n d a ta transmission links. This por t is most o ften used for dedicated local management.
CSMA/CD: Channel a ccess method used b y Etherne t and IEEE 80 2.3 stand ards in which de vices tr ansmit o nly af ter find ing the

data channel clear for some period of time. When two devices transmit simultaneously, a collision occurs and the colliding
devices delay their retransmissions for a random amount of time.

Flow Control: (IEEE 802.3X) A means of holding packets back at the transmit port of the connected end station. Prevents packet

loss at a congested switch port.

forwarding: The process of sending a packet toward its destination by an internetworking device.
full duplex: A system that allows packets to be transmitted and received at the same time and, in effect, doubles the potential

throughput of a link.

half duplex: A system that allows packets to be transmitted a nd received, but not at the same time. Con trast with full duplex.
IP address: Inter net P ro toco l ad dre ss. A unique ide ntifier fo r a device attached to a network using TCP/IP. T he address is written

as four octets separated with full-stops (periods), and is made up of a network section, an optional subnet section and a host
section.

LAN - Local Area Network: A network of connected computing resources (such as PCs, printers, servers) covering a relatively

small geographic area (usually not larger than a floor or building). Characterized by high data rates and low error rates.

latency: The delay between the time a device receives a packet and the time the packet is forwarded out of the destination port.
line speed: See baud rate.
main port: The port in a resilient link that carries data traffic in normal operating conditi ons.
MDI - Medium Dependent Interface: An Ethernet port connection where the transmitter of one device is connected to the

receiver of another device.
MDI-X - Medium Dependent Interface Cross-over: An E thernet port co nnectio n wher e the internal transmit and receive lines

are crossed.
MIB - Management Information Base: Stores a device's management characteristics and parameters. MIBs are used by the

Simple Network Management Protocol (SNMP) to contain attributes of their managed systems. The Switch contains its own
internal MIB.

multicast: Single packets copied to a specific subset of network addresses. These addresses are specified in the destination­address field of the packet.

protocol: A set of rules for communication between devices on a network. The rules dictate format, timing, seque ncin g and er ror
control.

server farm: A cluster of servers in a centralized location serving a large user population.
SLIP - Serial Line Internet Protocol: A protocol which allows IP to run over a serial line connection.
SNMP - Simple Network Management Protocol: A protocol originally designed to be used in managing TCP/IP internets.

SNMP is presently implemented on a wide range of computers and networking equipment and may be used to manage many
aspects of network and end station operation.

Spanning Tree Proto col (STP): A bridge-based system for providing fault tolerance on networks. STP works by allowing the
user to implement parallel paths for network traffic, and ensure that redundant paths are disabled when the main paths are
operational and enabled if the main paths fail.

STACK: A group of network devices that are integrated to form a single logical device.
standby port: The port in a resilient link that will take over data tr a nsmission if the main port in the link fails.
switch: A device which filters, forwards and floods packets based on the packet's destination address. The switch learns the

addresses associated with each switch port and builds tables based on this information to be used for the switching decision.
TCP/IP: A layered set of com munications protocols providing Telnet terminal emulation, FTP file transfer, and other services for

communication among a wide range of computer equipment.
telnet: A TCP/I P application proto col that provides virtual ter minal service, letting a user log in to another co mputer system and

access a host as if the user were connected directly to the host.
