Hi Vivek,
The SGE/SFE datasheets are in our older style of datasheet. The product number is the order number. In the new datasheets, there is an Ordering Table that includes the part numbers, the column is the Product Order ID.
The SGE models part number is the same as order number. The following webpage list all the models and the model numbers and order ID are the same:

In addition the SGE2000-G5 comes with default IPv6 support.
Also your local distributor should be able to help you with your product numbers.
