9.3.3 Restoring the System Configuration
Once the new SS7G20SHDD has been installed, the previous system configuration should be restored. The
ISO9660 format CD-ROM containing backup of the system configuration, System License, protocol licenses
and operating software, which was described in
Section 9.3.1, “Backing up the System Configuration” on
page 56 , should be inserted into the CD-ROM drive. The system will install the backup files from the CD-ROM
at startup and may automatically restart if a different version of the SS7G2x Software Distribution is being
installed.
After the restoration process has completed, the CD-ROM should be removed to prevent the backup
configuration from overwriting subsequent configurations.
