Restore
The Restore option allows qualified service personnel to load system
programming from either a diskette or from the hard disk into the processor
module memory.
This procedure is used either to program a new system if a disk was created
through surrogate mode programming, or to restore information (using a
backup disk) lost through system failure. It is also part of the upgrade
procedure.
Considerations
Review the following items before you begin the restore procedure.
The system will be forced idle during a restore procedure.
You must have a backup file containing system programming before
you use this procedure. See "Backup."
Features that were not programmed when the backup file was created
are reset to factory defaults.
The data restored reflects the number of extensions and lines
available on the system at the time the backup was created. The
remaining extensions and lines are set to the default values that are
initialized during a Restart (cold start).
Restore is terminated under the following conditions:
If fewer boards are listed on the disk than on the control unit
If any real board is out of sequence with the boards listed on the disk
If phantom boards are not listed last
If the operating mode of the system being restored is Hybrid/PBX, but
the control unit processor module has been modified to operate only
in Key mode
A successful restore is followed automatically by a Restart (cold start)
