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 any objects into the openings of the 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 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.
v

xStack® DGS-3420 Series Layer 2+ Managed Stackable Gigabit Switch Hardware Installation Reference Guide · 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/national wiring rules. · When connecting or disconnecting power to hot-pluggable power supplies, if offered with your system, observe
the following guidelines: o Install the power supply before connecting the power cable to the power supply. o Unplug the power cable before removing the power supply. o 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.
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.

Management Options Connecting the Console Port Connecting to the Switch for the first time Connecting to the Management Port Password Protection Assigning 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.

Press Enter in both the Username and Password fields. Then access will be given to enter commands after the command prompt DGS-3420-28SC:admin#

There is no initial username or password. 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.

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 | state [enable | disable] | gateway }
To view the status or IP settings, use the command: show out_band_ipif
To change settings for the out-of-band Management port in the web interface, use the following path: Management > Out of Band Management Settings

xStack® DGS-3420 Series Layer 2+ Managed Stackable Gigabit Switch Hardware Installation Reference Guide
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 and press the Enter key. 2. The Switch will then prompt the user to provide a password. Type the administrator and press the Enter key. 3. Once entered, the Switch will again ask the user to insert the same password again to verify it. Type the same password and press the Enter key. 4. A new administrative account is created once the “Success” prompt appears.
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”.

DGS-3420-28SC:admin# create account admin newmanager Command: create account admin 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.

The IP interface named System on the Switch can be assigned an IP address and subnet mask, and then be used to connect a management station to the Switch’s Telnet or Web-based management agent.

The system message Success indicates that the command was executed successfully. The Switch can now be configured and managed via Telnet and the CLI or via the Web-based management.

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.

34

xStack® DGS-3420 Series Layer 2+ Managed Stackable Gigabit Switch Hardware Installation Reference Guide
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.
