  Nope, there's no special hardware in the J90's Sparc5 (OWS).  It has a
FSBE/S card in it which implements a private ethernet between the OWS
and the IOS(s) on the J90.  All you need is the software and a
dig-it-out-of-the-closet SS5 with a FSBE.

  That's why CS6400s aren't more popular than they are amongst the
supers-at-home community, I suspect.
