1.2 Management Software & Interfaces
Management options available for this Managed Switch are listed below:
•Local Console Management
•Telnet Management
•SNMP Management
Console Program
The Managed switch has a built-in Command Line Interface (CLI) that allows you to
configure the system, monitor the status, and reset the system. You can use this CLI as
your 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 VT100 terminal or
a workstation running VT100 emulation software to the Managed switch RS-232 DB-9
console port directly. Telnet can also be used to login and access the CLI through network
connection remotely.
SNMP Management System
Standard SNMP-based network management system provides users a way 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 installation into your SNMP-based
network management system.
1.3 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.

1000Base-X SFP Port
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical
data communications 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, providing a host device designed primarily
for optical fiber communications to also communicate over unshielded twisted pair
networking cable.
SFP slot for 3.3V mini GBIC module supports hot swappable SFP fiber transceiver.
Before connecting other switches, workstation or Media Converter, make sure both
sides 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
match the SFP transfer model. To connect to 1000Base-SX transceiver, use the
multi-mode fiber cable that one side is male duplex LC connector type. To connect to
1000Base-LX transfer, use the single-mode fiber cable that one side is male duplex
LC connector type.
10/100Base-T RJ-45 Auto-MDI/MDIX Port
24 x 10/100Base-T RJ-45 Auto-MDI/MDIX ports are located at the front panel of the
Managed Switch. These RJ-45 ports enable 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 cable may be used.
10/100/1000Base-T RJ-45 Auto-MDI/MDIX Port
10/100/1000Base-T RJ-45 Auto-MDI/MDIX ports are located at the front or back of
the Managed Switch depending on the model that you purchased. These RJ-45 ports
allow users to connect their traditional copper-based Ethernet/Fast Ethernet/Gigabit
Ethernet devices to the network. All these ports support auto-negotiation and
MDI/MDIX auto-crossover, i.e. either crossover or straight through CAT-5E UTP or
STP cable may be used.
RS-232 DB-9 Port
The RS-232 DB-9 port is located at the rear panel of the Managed Switch. This DB-9
port is used for local, out-of-band management. Since this DB-9 port of the Managed
Switch is DTE, a null modem is also required to connect the Managed Switch and the
PC. By connecting this DB-9 port, it allows you to configure and check the status of
Managed Switch even when the network is down or disconnected.

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.
MIB for Network Management Systems
Private MIB (Management Information Bases) must be installed before you manage the
Switch through the SNMP-based network management system. The MIB file with the file
name extension “.mib” is shipped together with the Managed switch. If this file is not
provided with the Switch, please contact your sales representative.

2. COMMAND LINE INTEFACE (CLI)
This chapter introduces you how to use Managed Switch CLI, specifically in:
•Local Console
•Telnet
•Configuring the system
•Resetting the system
2.1 Using the Local Console
Local Console is always done through the RS-232 DB-9 or RJ45 DB-9 port and requires a
direct connection between the switch and a PC. This type of management is very useful
especially when the network is down and the switch cannot be reached by any other means.
You also need to use 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 desired setting 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 RS-232 DB-9 or 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.

2.2 Remote Console Management - Telnet
You can manage the Managed Switch via a 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 set up the assigned IP parameters of the Managed Switch,
•IP address
•Subnet Mask
•Default gateway IP address, if required
Step 2: Run Telnet.
Step 3: Log into the Switch CLI mode.
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
The Command Line Interface (CLI) of this Managed Switch is divided into three different
modes. After you enter the required username and password, you start from the User mode.
The commands available depend on which mode you are currently in. Enter a question mark
(?) at the system prompt to obtain a list of commands available for each command mode.
When you successfully access the Switch, you begin in Root directory. Enter your username
and password, and then you will be directed to User mode. In CLI management, the User
mode only provides users basic functions to operate the Managed Switch. If you would like
to use advanced features of the Managed Switch, such as, VLAN, QoS, Rate limit control,
you must enter the Enable or Configuration mode. The following table provides an overview
of this Managed Switch.
