I am extremely new to routers (other then home routers) and I have been trying to research some hardware compatibility for our Cisco 2621XM routers.<br />
<br />
I know the 2621XM has 2 Fast Ethernet interfaces integrated already but I have a need for a third. &nbsp;I have been trying to research compatible options but seem to running into conflicting information. &nbsp;I have been looking at the following module, can someone let me know if this is compatible with the 2621XM and if so what the minimum IOS version required? &nbsp;I am looking at the NM-1FE-TX.<br />
<br />
If this module is not compatible can someone recommend a Fast Ethernet module that is compatible with the 2621XM? &nbsp;I have both my WIC slots as well as the NM slot available in my configuration.<br />
<br />
Thank you,<br />

Cisco 2621XM Hardware Compatibility Question

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
