One cisco 2621xm can support one NM-1T3/E3 module?

I installed a NM-1T3/E3 module in one cisco 2621xm and the "sh ver"
command seems to show that the router is recognizing it:

options useful and follow the results of the command "sh int":

**********************************************
I unsuccessfully tried to replace the router (I cannot replace the
module as I have only one) and I tried to digit the following command
unsuccessfully,so, my question is: by supposing that I'm using the
right IOS as I believe, there are chances that cisco2621xm is not the
right chassis for a T3/E3 module?

 

Did you enter in the command "card type t3 <slot number here>"? By
default IOS won't reconize the card until you put this in.
