login in the unix-pc

[hernan.martinez]

I know this has been asked before, but I am new to this group; so, here it goes:

I recently inherited a 7300, It has unix loaded and some other stuff.  The
problem is that I do not have any of the passwords to login into the system.
Is there anyway to get in and change the passwords?  I already tried login
in as install, but no luck.  Any help will be greatly appreciated.

				Thanks in advance.
