Software update

After Secure Boot is enabled, and before upgrading to a new software release, the user must validate that the new software image is properly signed. The main reason for this additional verification on systems with Secure Boot enabled is because the system only boots Nokia-signed software images and does not boot unsigned or improperly signed images.

Use the following command to validate the signature of the TiMOS *.tim images contained in the software-image url location referenced in the command. This verification includes cpm.tim, iom.tim, support.tim, both.tim, kernel.tim, as well as the boot.ldr if present in CF3 directory.
