3.4 Console Port (Managed Switches Only)
If your switch has a console port, you can use a terminal
emulator for local management. Connect the male 9-pin end
of a console cable to the console port of the switch. Connect
the female end to a serial port (COM1, COM2 or other COM
port) of your computer. Configure the computer with terminal
emulation software to the following parameters:
• VT100 terminal emulation
• 9600 bps
• No parity, 8 data bits, 1 stop bit
• No flow control
