"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

HWIC-2FE is supported from IOS version 12.4(20)T IP Base and, if I am not wrong, only one card is supported on Cisco 1841 Router.
