How to reset password on 470 2

[storm14]

We have a 470 we can't get into (everything is set to local password in the config)---we think the password was mis-typed? How can the password be recovered or reset?

attach terminal (note the DB9 has pins 2-3 opposite to Extreme)
while powering on the switch, hold down Ctrl-C
wait for a few bootup lines, and you will be presented with a few one letter commands.
choose "i" and answer yes. this erases the config.
select "a" to continue bootup. Ctrl-Y to login. You now have factory defaults for all settings.

unplug the power and plug it back in with the space bar held down on the console. If you miss the boot menu, try again, it is a very fast process.
Once you get the "BootROM-> " prompt, enter "h" (for help) and you will see your options.
