I downloaded the new image into Cisco 2620, but now every time after loading a flash image and after checking RAM and board, the following error appears:

========================================

*** Watch Dog Timeout ***

PC = 0x808968ec, SP = 0x81112920

C2600 platform with 32768 Kbytes of main memory

=======================================

After this error, the router reboots. I dont know what to do as the prompt does not appear.

The full boot up sequence is:

Hi Friend,

If the router starts crashing after a configuration change or a change in the Cisco IOS software version, then it is probably software-related.

Please check this linmk for further troubleshooting
