I have a 3825 router with IP Base IOS on it. I received an upgrade CD that has SP Services on it but can't seem to get the .bin file from the CD onto the router to upgrade the IOS. Anyone know how to do this?

You need to copy the .bin file onto a pc, install a tftp server onto the same pc and then on the router

router# copy tftp flash

The router will then ask you for the IP address of the tftp-server ie. your PC and the name of the file you want to copy.

Depending on the size of the .bin file you may need to erase your existing IOS from flash.

Also make sure your router has enough memory to accept the new IOS.

Edit - use this link to find a free tftp server

issue "dir /all" in enable mode to see if you have enough memory for the new image on the concerned file system.
