Hello, according to this page:
Our 2811 should be able to handle 2 additional HWIC-1FE cards. However after I purchased one and installed it, I am getting errors in our log saying:
%GT96K_FEWAN-1-UNKNOWN_WIC: NM slot 0, wic card has an unknown id 53A
I even upgraded to the very latest IOS and am still getting these errors.
Anyone know what I can do here?
Actually is not strange that the card was not recognized with older IOS.
From the data sheet:
Note: For the HWIC-1FE and HWIC-2FE the minimum level is Cisco IOS 12.4(11) XJ.
Remember that an IOS that has letters at the end, is newer than one without letter.
So for example 12.4(11)XJ is "newer" that 12.(4)12.
