1. Connect Console Cable
Cisco provides a couple of ports for console access, such as Console port, Mini USB port, AUX port. I has a previous post "Using Cisco Mini USB Console Cable to Configure Cisco Switches and Routers" for Mini USB usage. Usually old fashion way to use console port is still prevailing.Configure the baud rate and character format of the PC or terminal to match these console port default characteristics:
- 9600 baud
- 8 data bits
- No parity
- 1 stop bit
2. Hold down MODE Button while powering on the device
Note: for Cisco routers and certain type of Cisco switch (2955), it will require press Break Button / Ctrl+Break on terminal window to interrupt boot procedure.
