This router is contain HWIC-2T and NM-8A/S.I search about crashinfo,it's CRC errors and must replaced RAM to troubleshooting.

But I finally replaced NM-8A/S to troubleshooting.

How to determine where the failure from the log？

Hi Kevin,

I think your router is experiencing a crash-boot-loop.

Try this:

1.  Remove all the network modules and HWIC cards;

2.  Eject the Compact Flash card;

3.  Using a media reader, delete some of the crashinfo files

4.  Insert the Compact Flash card back to the router;

5.  Power up the router.

But I troubleshoot this is to replace NM-8/AS finally.

I want to know how to directly judgments from these log damaged are NM-8/S  malfunction
