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.
.
■
Features that were not programmed when the backup file was created are
reset to factory settings.
■
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 factory settings that are initialized during a Restart
(cold start).
■
Restore is terminated under the following conditions:
— If fewer boards are listed on the backup disk than on the control unit.
— If any real board is out of sequence with the boards listed on the
backup 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).
!
WARNING:
An unsuccessful or terminated restore results in a System Erase
(frigid start). All calls are dropped. The system configuration is
erased. All system programming is lost and the system returns to the
factory settings. If the restore is being done remotely, the connection
is dropped immediately. If this happens, attempt to reconnect to the
control unit and immediately perform another restore. If this is not
successful, programming must be restored on site.
