Included by default.
Originally the IDSM-2 was going to be sold with and without the acceleration card (WS-SVC-IDSUPG).
However, during later stages of testing it was decided that the IDSM-2 would ONLY be sold WITH the acceleration card (WS-SVC-IDSUPG) pre-installed.
We do not even support the IDSM-2 with out the acceleration card.
This is also the reason the only part number for the IDSM-2 in the pricing sheet is a "BUN"dle price number that includes both the base card (WS-SVC-IDSM-2) and the acceleration card (WS-SVC-IDSUPG) together as a single price: WS-SVC-IDS2-BUN-K9 or WS-SVC-IDS2BUNK9= (when ordered as a spare).
