We have a NM-T3/E3-RF card that fits inside a 3800, but does not fit into a 3945.
The documentation says it works with 3900 ISR Routers.
Is there a cradle or adapter that is required?
Does the "RF" section of the part number differentiate this from a NM-T3/E3 card?
The NM-t3/E3-RF Is listed as an expansion module. I did find it on the internet but not on cisco. It was listed as compatable with the 3945E.
It did not show up in the Interfaces and modules listing:
-RF means Refurbished. These are discounted on the list price, but not everyone can order them.
Regarding the OP question, to install NM modules in ISR G2, you need SM-NM-ADPTR.
Thanks for the iformation. Right after posting, my friend found the info hidden in the Cisco document, and I removed the question. It looks like I can not rate your responses, but I appreciate the effort. Regards, jc
