Newer versions set password to "admin" by default. Since these routers are
sold through resellers (ISPs, etc..), they are not always identical when
the hit an end-user. Some resellers might change default passwords, some
may not.

In any case, this was discussed here last August, which ironically is the
period your build comes from. Changes have been made since then, including
implementation of a telnet password which must be entered before getting
the prompt and using the admin password (enable for IOS folks).
Unfortunately I don't know if the telnet password is set by default since
I went through an upgrade and not an out-of-box config.

The main problem I've had in dealing with FlowPoint security issues, of
which there are many, is the lack of information on their web site and the
nearly impossible task of getting a hold of their engineers. The software
releases and utilties can be found at ftp://ftp.systemv.com/pub/flopoint

I had to spend many hours tracking down a person for this info and I'm not
sure why they don't have a link on their home page. Don't expect too much
documentation on the ftp server, but at least you can grab a newer
revision of the software and settle some of these issues. Dropping telnet
access to the FP routers is probably a good idea regardless, though it's
not always an option.
