[Scott Harvanek]

David,

Thanks for pointing that out, I did read that and understand the available options/limitations between the 10G/40G interfaces. :)

I think the EQ version is the same in regards to the limitation we discovered.  At the time we purchased the cards, it wasn’t well documented as to how the 10 and 40Gbs ports could be used.  Juniper has since updated the documentation to specify the allowed port usage.
