Working with getcit on this issue and still not resolved. Changed DM to version 5.2 (from ver. 4.8) and error message when trying to access 8.5 - System Parameters has changed to:

"SVMi card ftp server should be running to use this page. Please turn it on."

Not sure if that's another clue...
Also, as far as I can tell, to view the SVMi MAC, you have to view/access 8.5 System Parameters, unless I am missing something, however I do not believe IP conflict is the problem here.
