WIC 2T not detected

Hi All,

Well I am in a pretty wierd situation. I have quite many routers in my lab and a new addition of 2621XM is the point of problem. It cann't detect WIC 2T cards. I tried to install cards in 2 of its slots but no vail. In those same slots ISDN card got detected and The WIC 2T cards are being detected by other routers i.e. 2610, 2611 etc.

This problematic router 2621XM is currently with 12.4(7), 128 MB Ram, 32 MB Flash. Please give some nice tips regarding this.

On startup this is the message about WIC slot.


Slot is empty or does not support clock participate

WIC slot is empty or does not support clock participate"

Thanks in advance.


Re: WIC 2T not detected

Free the router from other slots and try to install it on a another slot, if the problem still exist so i guess it's IOS issue.

Let me know if that gone work.

Please rate helpful posts.

No changing slot doesn't work. Even I inserted WIC 2T in a separate NM-1FE2W, That NM is detected but all of its ports including WIC2T and FE are not detected. "Show diag" states Port adapter as disabled
