!−−− Verify the bytes available
In the above example, the router has four files in the Flash. If you want to load another image that
requires more than 6623664 bytes, you would not have enough available memory. You would need to
erase one of the files to create room for an additional image. The example below shows the file
c5400−is−mz.121−5.T8 image being removed from the Flash.
