I want to try the local install procedure. I'm able to ftp the new ISO image to the RouteFinder but not to the root '/' directory. I receive a permission denied message. How do I login as 'su' to move the ISO file to the root '/' directory?

You first login as admin or loginuser user, then at the prompt, you type in su to login as su (root) user.

You will need to login as su (root) in order to move files around.
