Cisco 3620 not recognizing my 1-NM-1E2W

Hi all,

I have two 3620's and each with a 1-NM-1E2W unit (with a SERIAL module installed) and a 1-NM-1E1R2W unit (with a 56/64K serial module installed).

Both routers have 12.3.X Enterprise plus IPSec IOS as what I can tell. The image file is c3620-ik9o3s7-mz.123-12.bin

On one, i have the 1-NM-1E2W on slot (1) and the 1-NM-1E1R2W on slot (0). It boots up fine and detects both units.

The other router, when I have the 1-NM-1E2W on slot (1) gives me the following:

Would you like to enter the initial configuration dialog? [yes/no]: no

If I take take both units and switch them arround. The 1-NM-1E2W on slot (0) and the 1-NM-1E1R2W on slot (1) , they both get detected fine and the router boots up fine with no errors!

As far as i can see, both routers have the same configuration and IOS image file installed.

I know it's easy to say "Just leave it the way it works!" but I would like to learn what I must be doing wrong or have overlooked.

I'm studying towards my CCNA and have setup a small lab at home.

I have tried different things. Such as removing both units and installing one at a time, doing WRITE ERASE, reloading, and every time the 1-NM-1E2W is in slot (1) I get the error.

Thank you for your help, as I'm pulling out the hairs out of my head trying to figure this out.
