• 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.

o 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.

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, 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
uncertain that suitable grounding is available.

vii

DGS-3000 Series Layer 2 Managed Gigabit Switch Hardware Installation 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.

Switch Description

The DGS-3000 Series is part of the Layer 2 family of D-Link’s managed switch product line. The switches provide
wired Gigabit speed access for metro and campus networks. The two embedded 10G SFP+ ports on the DGS-3000­26TC guarantee performance during aggregation of numerous Gigabit connections. The DGS-3000 Series is
designed as a 1U rackmount case suitable for desktops and telecom cabinets. The DGS-3000-10TC is more compact,
using a 9-inch case that comfortably fits in telecom distribution boxes. The smaller dimensions provide better air flow
in limited spaces and also make cable management easier. The embedded alarm port of DGS-3000-26TC allows for
input of external sensors to detect potential threats such as open doors or cabinet overheating which then trigger
warning events. This is extremely useful for a device that may be widely deployed in any metropolitan environment.

The Series features the following list of switches:

• DGS-3000-10TC: 8-Port 10/100/1000 BASE-T + 2-Port Combo 10/100/1000BASE-T/SFP, L2 Management

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 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.

Command Line Interface through the Serial Port or remote Telnet

The user can also connect a computer or terminal to the serial console port to access the Switch. The command line
interface provides complete access to all Switch management features.

Connecting the Console Port

The front panel of the Switch provides a port that enables a connection to a computer monitoring and configuring 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 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:

• 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.

24

DGS-3000 Series Layer 2 Managed Gigabit Switch Hardware Installation Guide

NOTE:

• Under Properties, select VT100 for Emulation mode.

• Select Terminal keys for Function, Arrow and Ctrl keys. Make sure to use Terminal keys (not Windows keys)

are selected.

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 cord 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 DGS-3000 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 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 on the File menu in the HyperTerminal window by 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 on the next page will appear on the console. 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 prevention of unauthorized users from accessing the Switch
or changing its settings. This section tells how to log onto the Switch via out-of-band console connection or out-of­band Management port connection.

Upon initial connection to the Switch, the login screen appears (see example below).

DGS-3000-26TC Gigabit Ethernet Switch

Command Line Interface

Firmware: Build 1.00.004

Copyright(C) 2012 D-Link Corporation. All rights reserved.

UserName:

Figure 4-2 Initial screen, first time connecting to the Switch

Press Enter in both the Username and Password fields. Then access will be given to enter commands after the
command prompt DGS-3000-26TC: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.

Password Protection

The Switch does 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 lo g in, 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 <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.

26

DGS-3000 Series Layer 2 Managed Gigabit Switch Hardware Installation Guide

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 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.

The Switch's MAC address also appears in the Device Information and System Information windows of the Web­based management interface. The IP address for the Switch must be set before using 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.

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 SNM P age nt. S NMP def ines 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 version of SNMP to use to
monitor and control the Switch. The three versions of SNMP 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 SNM P 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.

27

DGS-3000 Series Layer 2 Managed Gigabit Switch Hardware Installation 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 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 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.

Introduction

The software functions of the Switch 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 bro w ser ,
such as Internet Explorer (version 5.5 and later), Netscape (version 8.0 and later), Mozilla Firefox (version 2.0 and
later), Safari (version 4.0 and later), or Google Chrome (version 6.0 and later). The browser acts as a universal access
tool and can communicate directly with the Switch using the HTTP protocol.

Logging onto the Web Manager

To begin managing the Switch, simply run the browser installed on your computer and point it to the IP address you
have defined for the device. The URL in the address bar should read something like: http://123.123.123.123, where
the numbers 123 represent the IP address of the Switch.

NOTE: The factory default IP address is 10.90.90.90.

This opens the management module's user authentication window, as seen below.
