3. Terminal Setup

To  configure  the  system,  connect  a  serial  cable  to  a 

COM 

port

 on a PC or notebook computer and to the RJ45 type 

of the console port of the Managed Switch.

A terminal program is required to make the software 
connection to the Managed Switch.

1. Run terminal program on the OS.

2. When the following screen appears, make sure that the 

COM port should be configured as:

  

 Baud: 115200

  

 Data bits: 8

 

 Parity: None

 

 Stop bits: 1

 

 Flow control: None

5. At  the 

“Switch  (config)#”

 prompt, enter the following 

command and press 

<Enter>

 as shown in Figure 5-2.

Switch (config)

# ip address 192.168.1.100 255.255.255.0

Switch (config)

# ip default-gateway 192.168.1.254

The previous command would apply the following settings 
for the Switch.

IP Address: 192.168.1.100
Subnet Mask: 255.255.255.0
Gateway: 192.168.1.254

Figure 5-2:

  IP Address Screen

6. Repeat Step 1 to check if the IP address is changed.

If  the  IP  is  successfully  configured,  the  Managed  Switch 

will apply the new IP address setting immediately. You can 
access the Web interface of the Managed Switch through 
the new IP address.

Note

If you are not familiar with console command 
or the related parameter, enter 

“?”

 anytime in 

console to get the help description.

4. Logon to the Console

Once the terminal is connected to the device, power on 
the Managed Switch and the terminal will display “running 
testing procedures”. Then, the following message asks to 
log-in user name and password. The factory default user 
name and password are shown as follows, and the login 
screen in Figure 4-1 appears.

Username: 

admin

Password:

The user can now enter commands to manage the 
Managed Switch. For a detailed description of the 
commands, please refer to the following chapters.

Note

1. For security reason, please change and 

memorize the new password after this first 
setup.

2. Only accept command in lowercase letter 

under console interface.

2. Requirements

 Workstations running Windows XP/2003/Vista/7/8/2008, 

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 COM Port (DB9) or 

USB-to-RS232 converter.

 The above Workstations have been installed with 

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

 Serial cable -- one end is attached to the RS232 serial 

port, while the other end to the console port of the 
Managed Switch.

 Ethernet Port Connection

  Network  cables  --  Use  standard  network  (UTP)  cables 

with RJ45 connectors.

 The above PC is installed with Web browser and JAVA 

runtime environment plug-in.

Note

It is recommended to use Internet Explore 
8.0 or above to access the Managed Switch. 
If the Web interface of the Managed Switch is 
not accessible, please turn off the anti-virus 
software or firewall and then try it again.

5. Configuring IP Address via the

 Console

The Managed Switch is shipped with default IP address as 
follows:

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 Switch, please use the procedures as follows:

  Show the current IP address

1. At the 

“Switch#”

 prompt, enter 

“configure”

.

2. At the 

“Switch(config)#”

 prompt, enter 

“show ip”

.

3. The screen displays the current IP address, subnet mask 

and gateway as shown in Figure 5-1.

Figure 5-1:

4. At the 

“Switch#”

 prompt, enter 

“configure”

.

6. Starting Web Management

The following shows how to start up the 

Web 

Management

 of the Managed Switch. Note the Managed 

Switch is configured through an Ethernet connection. Please 

make sure the manager PC must be set on the same

 IP 

subnet address

.

For example, the default IP address of the Managed Switch 
is 

192.168.0.100

, then the manager PC should be set at 

192.168.0.x

 (where x is a number between 1 and 254, 

except 100), and the default subnet mask is 255.255.255.0.
