Connecting to the Console Port  
The device provides an RS-232 serial port that enables connecting to a computer or terminal for monitoring and configuring 
the switch. The RS-232 serial port is a female DB-9 connector; implemented as a Data Terminal Equipment (DTE) 
connection. To use the console port, the following equipment is needed:  
•  A terminal or a computer with both a serial port and the ability to emulate a terminal. 
•  A null modem or crossover RS-232 cable with a female DB-9 connector for the console port on the switch. 
To connect a terminal to the console port: 
1.  Connect the female connector of the RS-232 cable directly to the console port. 
2.  Tighten the captive retaining screws. 
3.  Connect the other end of the cable to a terminal or to the serial connector of a computer running terminal 
emulation software.  
Set the terminal emulation software as follows: 
1.  Select either serial port:  
-  COM port 1 
-  COM port 2 
2.  Set the Baud Rate to 9600. 
3.  Set the data format to 8 Data Bits, 1 Stop Bit, and No Parity. 
4.  Set flow control to None.
