2811 and 12.4.24T IOS Troubles

Hello folks,

 

I have been beating my head against a wall trying to load the following IOSs on a 2811 with 256mb of Compact flash and 768k of memory.

 

These won't load:

c2800nm-adventerprisek9-mz.124-24.T8.bin

c2800nm-adventerprisek9-mz.124-24.T7.bin

c2800nm-adventerprisek9-mz.124-24.T6.bin

This one will: (caveat below)

c2800nm-adventerprisek9-mz.124-24.T2.bin

The caveat is when I load c2800nm-adventerprisek9-mz.124-24.T2.bin onto my 128MB Compact Flash it loads just fine. If I put that exact same file on the 256MB Compact Flash, it fails. The other  T6 - T8 IOSs will not load on either CF. Here is the output from the router:

All the documentation says the the router can have a max of 256MB of Compact Flash and 768k of ram. I saw a blog by a fellow that said he was running 12.4.24T8 Advanced Security so I figure this should work as well.

Any ideas?

 

Thanks!

  • your new CF card is not detected by the router it might be an issue with how the CF has been formatted try to follow this procedure in formatting the CF card so the router could use it.

    http://packetlife.net/blog/2009/nov/2/generic-compact-flash-cards-and-cisco/

    or it you are able to boot with the older CF Card try removing the old card and insert the new one and format it using the router command format

     

  • I used the technigque on packet life, but the it only partially worked. I had some strange out comes:

    When I formated the CF on the router and then inserted the CF into my PC, the CF still had an IOS on it. Weird.

    I deleted the IOS using the PC then reformated it on the router. I then TFTP'd c2800nm-adventerprisek9-mz.124-24.T2.bin and it worked with a 256MB CF.

    Then, after formating the second 256MB CF, I TFTP'd c2800nm-adventerprisek9-mz.124-24.T8.bin and it failed.

    So, I took the first 256MB CF, reformated it, and loaded c2800nm-adventerprisek9-mz.124-24.T8.bin and it worked!

    Now I need to figure out why it is failing on the second CF and load the third CF as well.

    Thanks for the help, it pointed me in the right direction. Still can't explain why formatting a CF would leave a file on it and why after formatting the other CFs they are not working either. I will keep fiddling with it.

     

     

  • Usually a defective CF has that symptom.
