Cisco 2800-Need to upgrade IOS, not getting prompt to erase current IOS image

[brianjoyce]

I am attempting to upgrade a 2811 to configure it as a hardware backup for any of our remote offices. I'm wanting to set it up with a basic configuration so that all we would have to change is IP addresses.

I need to upgrade the IOS to accomplish this. In order to load the new IOS image, I need to erase the current one. There is not enough memory to bring it in along with the current one. As you can see below, I am not getting a prompt to erase current IOS image:

DisRecRTR#copy tftp flash
Address or name of remote host []? 192.168.1.2
Source filename []? c2800nm-advipservicesk9-mz.124-24.T5.bin

Loading c2800nm-advipservicesk9-mz.124-24.T5.bin from 192.168.1.2 (via FastEthernet0/1): !
%Error copying tftp://192.168.1.2/c2800nm-advipservicesk9-mz.124-24.T5.bin (Not enough space on device)

Any ideas?

Hi

You can manually delete the existing image by using the command:

delete flash:filename.bin

Hope this helps

I guess I was afraid to do that in case it rendered the router unusable...

Thanks, I'll try that in a few minutes.

Brian,

Deleting an image will not harm anything unless the switch is powered down.  In that case you would have to bring the switch up in ROMMON to upload an image.  While this is an option, it is not recommended.  Deleting the image and uploading a new one BEFORE powering down or reloading the switch (don't forget to set your boot variable!!!) is recommended.

If you have a spare compact flash card, you can copy the new image onto that then get the router to boot on the new image.  In the event that the new one doesn't work, you can then put the original back in and boot from that.
