You need a minimum IOS of 12.4(15)T to use this card -

Note that you 12.4 mainline will not do as support for this card was added in the T train.

BTW, because of the nature of the "T" train, you might want to avoid using a version higher than 12.4(15)T although you'll probably want to use the latest patch version, which I think is now T9 for 12.4(15)T.

Hi Mayank,

Easy solution to your lack of flash capacity. Go to your nearest electronics shop and purchase a CF no greater than 2Gb. Insert it and format the new CF before loading the IOS.

I've done this numerous times successfully.

NOTE: If you are interested, you can also boot from USB. (

Hope this helps.
