What IOS are you running now? DOes it see the hardware?

12.3-13 and it does not see the card
12.3(14)T is the earliest release that supported that VWIC.  Also, if you have a smartnet contract, you can access the IOS Upgrade Planner, which will let you know which software is supported with your system configuration.
