Per your suggestion I opened a ticket with LSI this AM, and, when I get something definitive will post back. If there is a sound FAQ on I2c, SGPIO, SES/SES-2, cabling along with common problems and use cases I have not found it - I can dream though. A lot of reading internet posts right or wrong and reading between the lines in manuals. Or I may just be getting older. Frustrating. Thank you again.
