FDDI ring works in what system states

We have a backend FDDI ring between 5 Alpha systems (Tru64 and OpenVMS)
using DEFPA-DC cards. I was told the ring would still function with
one of the system down as long as it was not completely powered off. We
have upgraded the O/S on a couple of these systems on this ring at
different times lately and each time during the upgrade traffic on the
ring was affected (could not ping between several systems.

Is it true that the ring should still function w/ one system down? Or
is it only funtional at run level 3 (network started)? Does it matter
whether it's at the SRM console or single-user mode?

Thanks.
