Cisco network module not showing up in configuration

The router (Cisco 3725) has two integrated FE ports but I added a NM-1FE-TX so I would have a third. The module shows up in a inventory list but not under the version or config. I confirmed the card works by putting it in a 2600 router and the card performed fine. The diag shows the port as disabled? Is there a way to determine if this platform does not support the card which seems odd since it works fine with the 2600s.
