This is for you folks that have an old 2900XL switch. So old that you need to troubleshoot, but you've forgotten the password to get in.
This was tested on 12.05 code.

1) Hold the "Mode" button while connecting the power cord (careful, electric current running through your body is very panful from what I've heard).
2) I let go of the button after 15 or 20 seconds, but there is an official number of seconds (see CCO at http://www.cisco.com).
3) You'll be be dropped at the "switch:" prompt.
4) Type "flash_init" and press enter.
5) Type "load_helper" and press enter.
6) Type "rename flash:config.text flash:config.old" (or .new, or whatever you like that's different from the original name :) ) and press enter.
7) Type "boot" and press enter.
8) When the switch boots up type "no" and press enter to bypass setup.
9) Press "Enter"
10) Type "rename flash:config.old flash:config.text" and press enter.
11) Type "copy flash:config.text system:running-config" and press enter.
12) Press "Enter".
13) Now you will be back to your old configuration.

Don't forget to change you passwords to something you know, or you'll be doing this all over again!
