Note about simultaneously connections 
You cannot connect to the Ethernet Switch simultaneously by serial console and Telnet. 
You can connect to the Ethernet Switch simultaneously by web browser and serial 
console or by web browser and Telnet. However, we strongly suggest that you do NOT 
use more than one connection method at the same time. Following this advice will allow 
you to maintain better control over the configuration of your Ethernet Switch. 
Useful tools for serial communiction 
Windows XP: We recommend using Hyper Terminal Program, which is installed under 
Windows XP operating system. 
Windows 7: Unfortunately the Hyper Terminal Program is no longer available in Windows 
7. Either use a commercial tool for serial communication or alternatively you can use a 
freeware tool like PuTTY or ucon.   
Example of serial connection via Hyper Terminal 
Before running Hyper Terminal Program, use an RJ45 to DB9-F (or RJ45 to DB25-F) cable to 
connect to the Ethernet Switch’s RS-232 Console port to your PC’s COM port. 
After starting Hyper Terminal Program perform the following steps to access the RS-232 Console 
utility. 
From the Windows desktop, click Start  Programs  Accessories  Communications  
Hyper Terminal. 
Start Hyper Terminal and enter a name of your choice for the new connection. Select the appropriate 
COM port for console connection in the “New Connection” window.
