How to get series number of BIG-IP

Hi,

 

 

Since BIG-IP has two types (BIG-IP6400 and BIG-IP1500), is it possible if I want to get this series number (6400 or 1500) by using the function of iControl?

 

I tried with get_product_information function, but the results do not include the series number.

 

Please let me know how I should do.

 

 

Thanks,
