To perform the configuration through RS-232 console port, the switch’s serial 

port must be directly connected to a DCE device, for example, a PC, through      
RS-232 cable with DB-9 connector. Next, run a terminal emulator with the default 
setting of the switch’s serial port. With this, you can communicate with the switch.  

In the switch, RS-232 interface only supports baud rate 57.6k bps with 8 data 

bits, 1 stop bit, no parity check and no flow control. 

 

 
 

 

 
 
 
 
 
 
 
 
 
 

 
 

 

 

 

 

To configure the switch, please follow the procedures below: 

1. 

Find the RS-232 DB-9 cable with female DB-9 connector bundled. 
Normally, it just uses pins 2, 3 and 7. See also Appendix B for more 
details on Null Modem Cable Specifications. 

2. 

Attaches the DB-9 female cable connector to the male serial RS-232 
DB-9 connector on the switch. 

3. 

Attaches the other end of the serial RS-232 DB-9 cable to PC’s serial 
port, running a terminal emulator supporting VT100/ANSI terminal with 
The switch’s serial port default settings.  For example, 
Windows98/2000/XP HyperTerminal utility. 

Note: The switch’s serial port default settings are listed as follows:  

Baud rate 

 

 

 

              57600

4. 

When you complete the connection, then press <Enter> key. The login 
prompt will be shown on the screen. The default username and 
password are shown as below:
