1.2 Management Options
Switch management options available are listed below:
Local Console Management
Telnet Management
SNMP Management
WEB Management
SSH Management
Local Console Management
Local Console Management is done through the RS-232 DB-9 Console port located on the
rear panel of the Managed Switch. Direct RS-232 cable connection between the PC and the
Managed switch is required for this type of management.
Telnet Management
Telnet runs over TCP/IP and allows you to establish a management session through the
network. Once the Managed switch is on the network with proper IP configurations, you can
use Telnet to login and monitor its status remotely.

10
SSH Management
SSH Management supports encrypted data transfer to prevent the data from being “stolen”
due to remote management. You can use PuTTY, a free and open source terminal
emulator application which can act as a client for the SSH, to gain access to the Managed
Switch.
SNMP Management
SNMP is also done over the network. Apart from standard MIB (Management Information
Bases), an additional private MIB is also provided for SNMP-based network management
system to compile and control.
Web Management
Web Management is done over the network and can be accessed via a standard web
browser, such as Microsoft Internet Explorer. Once the Managed switch is available on the
network, you can login and monitor the status of it through a web browser remotely or locally.
Local Console-type Web management, especially for the first time use of the Managed
Switch to set up the needed IP, can be done through one of the 10/100Base-TX 8-pin RJ-45
ports located at the front panel of the Managed Switch. Direct RJ-45 LAN cable connection
between a PC and the Managed Switch is required for Web Management.
1.3 Management Software
Following is a list of management software options provided by this Managed Switch:
Managed Switch CLI interface
SNMP-based Management Software
Web Browser Application
Console Program
The Managed Switch has a built-in Command Line Interface called the CLI which you can
use to:
Configure the system
Monitor the status
Reset the system
You can use CLI as the only management system. However, another network management
option, SNMP-based management system, is also available.
You can access the text-mode Console Program locally by connecting a VT-100 terminal -
or a workstation running VT100 emulation software - to the Managed Switch RS-232 DB-9
Console port directly. Or, you can use Telnet to login and access the CLI through network
connection remotely.

11
SNMP Management System
Standard SNMP-based network management system is used to manage the Managed
Switch through the network remotely. When you use a SNMP-based network management
system, the Managed Switch becomes one of the managed devices (network elements) in
that system. The Managed Switch management module contains an SNMP agent that will
respond to the requests from the SNMP-based network management system. These
requests, which you can control, can vary from getting system information to setting the
device attribute values.
The Managed Switch‟s private MIB is provided for you to be installed in your SNMP-based
network management system.
Web Browser Application
You can manage the Managed Switch through a web browser, such as Internet Explorer or
Netscape, etc.. (The default IP address of the Managed Switch port can be reached at
“http://192.168.0.1”.) For your convenience, you can use either this Web-based
Management Browser Application program or other network management options, for
example SNMP-based management system as your management system.
1.4 Management Preparations
After you have decided how to manage your Managed Switch, you are required to connect
cables properly, determine the Managed switch IP address and, in some cases, install MIB
shipped with your Managed Switch.
Connecting the Managed switch
It is very important that the proper cables with the correct pin arrangement are used when
connecting the Managed switch to other switches, hubs, workstations, etc..
100/1000Base-X SFP Port
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical
data communication applications. It interfaces a network device mother board (for a
switch, router or similar device) to a fiber optic or unshielded twisted pair networking
cable. It is a popular industry format supported by several fiber optic component
vendors.
SFP transceivers are available with a variety of different transmitter and receiver types,
allowing users to select the appropriate transceiver for each link to provide the required
optical reach over the available optical fiber type. SFP transceivers are also available
with a "copper" cable interface, allowing a host device designed primarily for optical
fiber communications to also communicate over unshielded twisted pair networking
cable.

12
SFP slot for 3.3V mini GBIC module supports hot swappable SFP fiber transceiver.
Before connecting the other switches, workstation or Media Converter, make sure both
side of the SFP transfer are with the same media type, for example, 1000Base-SX to
1000Base-SX, 1000Bas-LX to 1000Base-LX, and check the fiber-optic cable type
matches the SFP transfer model. To connect to 1000Base-SX transceiver, use the
multi-mode fiber cable with male duplex LC connector type for one side. To connect to
1000Base-LX transfer, use the single-mode fiber cable with male duplex LC connector
type for one side.
10/100/1000Base-T RJ-45 Auto-MDI/MDIX Port
4 x 10/100/1000Base-T RJ-45 Auto-MDI/MDIX ports are located at the front of the
Managed Switch. These RJ-45 ports allow users to connect their traditional copper-
based Ethernet/Fast Ethernet devices to the network. All these ports support auto-
negotiation and MDI/MDIX auto-crossover, i.e. either crossover or straight through
CAT-5 UTP or STP cables may be used.
RJ-45 DB-9 Port
The RJ-45 DB-9 port is located on the front panel of the Managed Switch. This RJ-45
DB-9 port is used for local, out-of-band management. This DB-9 port is DTE; therefore,
a null modem is required to connect the Managed Switch and the PC. With a
connection through RJ-45 DB-9 port, users can configure and check the Managed
Switch even when the network is down.
IP Addresses
IP addresses have the format n.n.n.n, (The default factory setting is 192.168.0.1).
IP addresses are made up of two parts:
The first part (for example 192.168.n.n) refers to the network address that identifies the
network where the device resides. Network addresses are assigned by three allocation
organizations. Depending on your location, each allocation organization assigns a
globally unique network number to each network which is intended to connect to the
Internet.
The second part (for example n.n.0.1) identifies the device within the network.
Assigning unique device numbers is your responsibility. If you are unsure of the IP
addresses allocated to you, consult with the allocation organization where your IP
addresses were obtained.
Remember that an address can be assigned to only one device on a network. If you
connect to the outside network, you must change all the arbitrary IP addresses to comply
with those you have been allocated by the allocation organization. If you do not do this, your
outside communications will not be performed.

13
A subnet mask is a filtering system for IP addresses. It allows you to further subdivide your
network. You must use the proper subnet mask for the proper operation of a network with
subnets defined.
MIB for Network Management Systems
Private MIB (Management Information Bases) is provided for managing the Managed Switch
through the SNMP-based network management system. You must install the private MIB
into your SNMP-based network management system first.
The MIB file is shipped together with the Managed Switch. The file name extension is “.mib”
that allows SNMP-based compiler can read and compile.

14
2. Command Line Interface (CLI)
This chapter introduces you how to use Command Line Interface (CLI), specifically in:
Local Console
Telnet
Configuring the system
Resetting the system
The interface and options in Local Console and Telnet are the same. The major difference
is the type of connection and the port that is used to manage the Managed Switch.
2.1 Using the Local Console
Local Console is always done through the RS-232 DB-9 port and requires a direct
connection between the switch and a PC. This type of management is useful especially
when the network is down and the switch cannot be reached by any other means.
You also need the Local Console Management to setup the Switch network configuration for
the first time. You can setup the IP address and change the default configuration to the
desired settings to enable Telnet or SNMP services.
Follow these steps to begin a management session using Local Console Management:
Step 1: Attach the serial cable to the RJ-45 DB-9 port.
Step 2: Attach the other end to the serial port of a PC or workstation.
Step 3: Run a terminal emulation program using the following settings:
Emulation VT-100/ANSI compatible
BPS 9600
Data bits 8
Parity None
Stop bits 1
Flow Control None
Enable Terminal keys
Step 4: Press Enter to access the CLI (Command Line Interface) mode.

15
2.2 Remote Console Management - Telnet
You can manage the Managed Switch via Telnet session. However, you must first assign a
unique IP address to the Switch before doing so. Use the Local Console to login the
Managed Switch and assign the IP address for the first time.
Follow these steps to manage the Managed Switch through Telnet session:
Step 1. Use Local Console to assign an IP address to the Managed Switch
IP address
Subnet Mask
Default gateway IP address, if required
Step 2. Run Telnet
Step 3. Log into the Switch CLI
Limitations: When using Telnet, keep the following in mind:
Only two active Telnet sessions can access the Managed Switch at the same time.
2.3 Navigating CLI
When you successfully access the Managed Switch, you will be asked for a login username.
Enter your authorized username and password, and then you will be directed to User mode.
In CLI management, the User mode only provides users with basic functions to operate the
Managed Switch. If you would like to configure advanced features of the Managed Switch,
such as, VLAN, QoS, Rate limit control, you must enter the Configuration Mode. The
following table provides an overview of modes available in this Managed Switch.

NOTE: By default, the model name will be used for the prompt display. You can change
the prompt display to the one that is ideal for your network environment using the
hostname command. However, for convenience, the prompt display “Switch” will be used
throughout this user’s manual.

2.3.4 Login Username & Password
Default Login
When you enter Console session, a login prompt for username and password will appear to
request a valid and authorized username and password combination. For first-time users,
enter the default login username “admin”and “press Enter key”in password field (no
password is required for default setting). When system prompt shows “Switch>”, it means
that the user has successfully entered the User Mode.
For security reasons, it is strongly recommended that you add a new login username and
password using User command in Configuration Mode. When you create your own login
username and password, you can delete the default username (admin) to prevent
unauthorized accesses.
Enable Mode Password
Enable mode is password-protected. When you try to enter Enable Mode, a password
prompt will appear to request the user to provide the legitimate passwords. Enable Mode
password is the same as the one entered after login password prompt. By default, no
password is required. Therefore, press Enter key in password prompt.

Forgot Your Login Username & Password
If you forget your login username and password, you can use the “reset button” on the front
panel to set all configurations back to factory defaults. Once you have performed system
reset to defaults, you can login with default username and password. Please note that if you
use this method to gain access to the Managed Switch, all configurations saved in Flash will
be lost. It is strongly recommended that a copy of configurations is backed up in your local
hard-drive or file server from time to time so that previously-configured settings can be
reloaded to the Managed Switch for use when you gain access again to the device.
2.4 User Mode
In User Mode, only a limited set of commands are provided. Please note that in User Mode,
you have no authority to configure advanced settings. You need to enter Enable Mode and
Configuration Mode to set up advanced functions of the Switch. For a list of commands
available in User Mode, enter the question mark (?) or “help”command after the system
