So do a lot of HP/Compaq servers with integrated lights out management.
Don't think you even need to power cycle (whether you're brave enough to
go poking around the deep innards of an energized server is another
matter).  I know the DIP switch on older DL385's is a micro DIP switch
and it's inconveniently located in the middle of the server behind some

The good part is that you can clear out unknown passwords as long as you
have access to the chassis innards.  The bad part is that I've seen these
left in password bypass mode (though the BIOS thoughtfully warns you of
the status if you do that).

With 24 million small businesses in the US alone, that's way too many apples.
