This was taken from Ciscos website and modified for in procedure examples-


 I recently used this to recover the password on my test switch, a Catalyst 6509.

This will work on the following switches:
      Catalyst 2900
      Catalyst 2900 Series G
      Catalyst 2926
      Catalyst 4000
      Catalyst 4840G
      Catalyst 4908G-L3
      Catalyst 5000
      Catalyst 5500
      Catalyst 6000

Step-by-Step Procedure with examples:

1.Attach a terminal or PC with terminal emulation to the console port of the switch. Use the following terminal settings:

          9600 baud rate
          no parity
          8 data bits
          1 stop bit

2.Turn off the switch and then turn it on.

! Important You must complete steps 3 through 7 within 30 seconds after you turn the switch off and on and the first time you see the password prompt.!

3.Press Enter at the password prompt to enter a null password.
