This card is either 24 x 10 or 6 x 40, not both. I believe you can also a combination of 3 x 40 and 12 x 10. 240G max. The 6 x 40 are Pic 2 and Pic 3, or 2/0-2/2 and 3/0-3/2. Disable the 0/0-0/11 and 1/0-1/11 and then enable 2 and 3 and your 40G ports should then come alive. See bottom of this URL:
