This is a new setup we are doing:
Although SHOW DIAG sees the NM-4B-S/T module installed in slot 2 of the router, we are unable to config the interfaces, because the interfaces are not seen by teh router.
IOS version is 12.3(21) and image name is c3640-js-mz.123-21.bin.
When we move the NM-4B-S/T to slot 3 it works fine. Assuming that slot 2 of this 3640 has a problem we tried another 3640 and again the same NM-4B-S/T in slot 2 of the second 3640 also shows the same symptom. I don't suspect the NM-4B-S/T module because it works fine in slot 3 of both routers.
What am I missing?
