Cisco Catalyst
Step-by-Step Procedure
1. Attach a terminal or PC with terminal emulation (for example, Hyper Terminal) to the console port of the switch. Use the following terminal settings:
o Bits per second (baud): 9600
o Data bits: 8
o Parity: None
o Stop bits: 1
o Flow Control: Xon/Xoff
Note: For additional information on cabling and connecting a terminal to the console port, refer to Connecting a Terminal to the Console Port on Catalyst Switches.
2. Unplug the power cable.
3. Hold down the mode button located on the left side of the front panel, while reconnecting the power cable to the switch.
For 2900/3500XL and 3550 Series switches: release the mode button after the LED above Port 1x goes out.
Note: LED position may vary slightly depending on the model.
Catalyst 3524XL
For 2950 Series switches: release the mode button after the STAT LED goes out.
Note: LED position may vary slightly depending on the model.
