I have a 2600 series router, about 2 1/2 years old. After a few months on the shelf, I plugged it back in and entered config information.
On every "reload" or power-down, it loses its configuration settings and resets back to factory defaults. I need to enter all the information again.
Following Cisco documents, I tested and erased the memory, it tested fine. I replaced the 8 MB NVRAM module with 2 others and reflashed these with 123.13 firmware.
No problems or errors on testing or reflashing NVRAM.
Still the same, does not keep settings after reload or power down.
Anyone have any ideas on how to solve this? Is there a battery under the main board that I am not seeing?
Thank you in advance
