Hi Kodiak,
The only thing that I would recommend is reviewing the NetApp Hardware Universe to verify the slot priority for the new HBA card. Based on the platform it would probably be slot 1 and if slot 1 is in use then slot 2.
After you install the card, you may want to boot into maintenance mode (boot menu, option 5) to verify you can see the card.
Let us know if you have any other questions or concerns.
Thanks
Team NetApp
