Short for Signed . This proves that the cryptographic checksums within the image match Cisco's internal signing authorities to prevent unauthorized file manipulation.

After the file copy completes, the system reboots into the Post-Install setup, often skipping hardware-level verification steps, as described in this installation overview .
