Requirements

The managed switch provides a remote login interface for
management purposes. The following equipment is necessary
for further management:

 Workstations running Windows

®

XP / 2003 / Vista / 7 / 8 /
2008 / 10, MAC OS X or later, Linux, UNIX, or other
platforms are compatible with TCP/IP protocols.

 Workstations are installed with Ethernet NIC (Network

Interface Card)

 Serial port connection (Terminal)

 The above workstations come with a COM Port (DB9)

or USB-to-RS232 converter.

 The above workstations have been installed with a

terminal emulator, such as Hyper Terminal included in
Windows XP/2003.

 Serial cable – One end is attached to the RS232

serial port, and the other end is attached to the
console port of the managed switch.

 Ethernet port connection

 Network cables – Use standard network (UTP) cables

with RJ45 connectors.

 The above workstations have a web browser and

JAVA runtime environment plug-in installed.

Note: We recommend using Internet Explorer 11.0 or later to
access the managed switch. If the web interface of the

managed switch is not accessible, turn off the anti-virus
software or firewall and then try it again.

Terminal setup

To configure the system, connect a serial cable to a COM port
on a PC or notebook computer and to a serial (console) port on
the managed switch.

Figure 2: Console connectivity

A terminal program is required to make the software connected
to the managed switch. Windows' Hyper Terminal program

may be a good choice. The Hyper Terminal can be accessed
from the Start menu.

1. Click Start > Programs > Accessories > Hyper
Terminal.

2. When the following screen appears, ensure that the COM
port is configured as shown below. Click OK when finished
with configuration.

3. Log in to the console. After the terminal has been
connected to the device, power on the managed switch.
The terminal displays “running testing procedures”.

When the following dialog box in Figure 3 below appears,
type the factory default user name "admin" and password

“admin”.

User name: admin

Password: admin

Note:

1. For security purposes, change and memorize the new
password after this first setup.

2. Only commands in lowercase letters are accepted in the
console interface.

Configuring the IP address

The managed switch is shipped with the default IP address
shown below:

IP Address: 192.168.0.100
Subnet Mask: 255.255.255.0

To check the current IP address or modify a new IP address
for the managed switch, use the following procedures:

Display of the current IP Address

1. At the “#” prompt, type “show ip interface brief”.

2. The screen displays the current IP address.

Configuration of the IP address

3. At the “#” prompt, type the following command and press
Enter as shown in Figure 5.

Switch# configure terminal
Switch(config)# interface vlan 1
Switch(config-if-vlan)# ip address 192.168.1.100

255.255.255.0

The previous command would apply the following settings
for the managed switch.

IP Address: 192.168.1.100

Subnet Mask: 255.255.255.0

4. Repeat step 1 to check if the IP address has changed.

Store the current switch configuration

5. At the “#” prompt, type the following command and press
Enter.

# copy running-config startup-config

Figure 6: Saving current configuration command screen

If the IP is successfully configured, the managed switch applies
the new IP address setting immediately. Access the web
interface of the managed switch through the new IP address.

Note: If unfamiliar with the console command or the related
parameter, type “help” in the console to obtain the Help
description.

Starting web management

The section describes how to start up the web management
function for the managed switch. Note that the managed switch
