Gadzoox used to do that... the management modules for their hubs had  
factory set random passwords.  It's provided on a sticker with the card,  
so you can put it where you want -- just don't lose it, because that's  
only place it exists (without breaking out a JTAG debugger.)

Yes, their later gear has standard default passwords.
