root@(default)(cfg-sync Standalone)(Active)(/Common)(tmos) load sys ucs XXXXXX.ucs no-license no-platform-check
Replace all configuration on the system? (y/n) y
Processing UCS file: /var/local/ucs/XXXXX.ucs
Installing full UCS () data, excluding license file.
Saving active configuration...
The hostname is set to default
Extracting manifest: /var/local/ucs/XXXXXX.ucs
