Step 7
From the displayed output of the
dir /all flash:
command, write down the names and directory locations
of the files that you can delete. If you cannot delete any files, you must upgrade your compact flash
memory card. See the hardware installation guide for your router.
Note
Do not delete the system image that the router already uses. If you are not sure which files can
be safely deleted, either consult your network administrator or upgrade your compact flash
memory card to a size that can accommodate both the existing files and the new system image.
See the hardware installation guide for your router.
