NET-APP-SUP-250 Alpha license question

Can anyone confirm if the VAX or Alpha NET-APP-SUP-250 licensing VAX- or VMSCluster support is for the full cluster support, or the client one that does not let the system it is on provide a vote towards quorum?
The info I've found so far is generic and doesn't state it clearly (shows the same working for cluster support for -250, -300, and -400).
Looking at waking up a long dormant box (assuming it works) to act as a vote-only node in a 3 node LAVC that is likely to lose its old an cranky   shared storage.
Thanks
