  • Verify the image you uploaded.

    Is it correct version for your hardware (XM/non-XM)?

    Is the feature set supported with your hardware - it might require more RAM?

     

    Try again with a different IOS - the smallest you can find if you are uploading using console

  • Yes, it might have memory issue. It can't load the IOS even if you have the valid one and it has been installed successfully.

    You can choose a lower sized IOS & give a try.

    HTH

  • ok, the exact hardware is 2610XM and it supports xmodem,

    I have similar router installed with c2600-adventerprisek9-mz.124-19 (29  MB)

    I tried this and tried c2600-i-mz.123-26 (7 mb)

    both of them is the same issue,

  • the problem as I beleive is with decompressing the IOS ??

    One of my Cisco 3600 routers was having same issue & I had tried to load an IOS via xmodem for a couple of time but couldn't accomplish. I suspected it to be the hardware issue and never tried to work on that again. 

    In you case, I would also recommend to try with different IOSes & try to diagnose the issue. If not done, consider it to be the hardware issue since it is very older platform which doesn't even support for loading IOS with TFTP.

    Good luck! 

  • You can use TFTPDNLD to upload IOS to 2600XM, but it seems to be a hardware error.

    have a few of them myself, I use them as equipment shelfs in my rack 

  • good news,

    I detected one of the RAM was making the error issue,

    I removed it and kept only one. then I tried to install the IOS and it worked.

    now the router has only 64 mb RAM !

    is that OK ?

  • If you have successfully loaded the IOS & you are able to boot the router properly, then it doesn't matter whatever the configuration is.

    Good luck!
