Faulty NM-4A/S?

Hi All,

I'm having a problem with a NM-4A/S and a 2620 router.

The NM-4A/S is identified in the 2620 as a NM-4T (which is unsupported). If I try it in a 2651XM it coms up as an unknown port adaptor.

The IOS on the 2620 is 12.3(19a) and the 2651XM is 12.4(18). According to the following link, the NM-4A/s should be supported.


As a test, I put the same NM-4A/S into a 3620, running 12.1 and it comes up as a Mueslix-4T

Now, this NM was sitting in a drawer for a long time (and may have come via eBay) Is it possible that an NM-4A/S could actually be a NM-4T? or could it be faulty? The back plate of the card does clearly say NM-4A/S

Thanks for any input.

Hi Paila,

I think you may have misunderstood me.

I know that the NM-4T is not supported in the 2600 series, but the card I installed was marked as being a NM-4A/S which is supported in the 2600 series.
