Intel X520-DA2 or X520-SR2?

I was donated some hardware, including an Intel 10G card with 2x SFP+ slots. However, I can't figure out if this is the '-SR2' (compatible with fiber modules) or '-DA2' (intended for DAC only) model within the X520 series. As far as I can tell, these cards look identical to the naked eye. Is it possible to tell which it is from within FreeBSD, or is it basically trial and error with modules?

A little info on it:
Code:

My hunch is both these cards looks identical to the OS as they have no way of knowing which is which, but I'd love to be proven wrong.
 
Thanks, I didn't realize you could get the model from the serial number. Unfortunately it's the DAC model.

And yes, I was pretty sure the driver was the same. You can see it's recognized and working (in theory, anyway).
 
There are not physical differences in the cards from my understanding.
The SR2 models included SFP+ modules. The type=SR(short range)
 
According to Intel, you cannot put SFP+ optical transceivers in the DA card, period. I'm not sure how they enforce this, but I really don't want to deal with vendor-specific cabling between hosts and switches, especially when both ends would be different vendors.
