before you power on the switch, start the terminal emulation session so that you can see the output display from the power-on self-test (post).

    the terminal-emulation software—frequently a pc application such as hyperterminal or procomm plus—makes communication between the switch and your pc or terminal possible.

    step 1 start the terminal-emulation program if you are using a pc or terminal.

    step 2 start a terminal-emulation session.

    step 3 configure the baud rate and character format of the pc or terminal to match these console port default characteristics:

    1、9600 baud

    2、8 data bits

    3、1 stop bit

    4、no parity

    5、none (flow control)
