with a terminal-emulation program (such as HyperTerminal) directly to the switch console port.
STEP 2: Configure the terminal-emulation program settings.
When using the management method, configure the terminal-emulation program to use the following parameters (you can
change these settings after login):
Default parameters:
• 115,200 bps
• 8 data bits
• No parity
• 1 stop bit
STEP 3: Press the “Enter” key.
The Command Line Interface (CLI) screen should appear.
STEP 4: Log on to Exec Mode (View Mode).
At the “switch_a login:” prompt, type in “root” and press <Enter> to log on to Exec Mode (or View Mode). The “switch_a>”
prompt will show on the screen.
