Restoring backed up data from a USB memory device to a PBX.
Follow the procedure below to restore the backed up data to a PBX.
Note: The restoration process requires that the PBX is initialised, which returns the PBX to its factory
default state.
Under the following conditions, restoration may not be possible, even though the PBX has been initialised.
• The USB memory device hardware is faulty.
• The data on the USB memory device has become corrupted.
• The USB memory device is removed from the USB port of the PBX during the restoration process.
To minimise the potential of a failed backup, connect the USB memory device to a PC to confirm the USB
memory device is operational and that the backup data is intact before starting this restore process.
1. The PBX must be in a powered-off state.
2. Insert the USB memory device with the backup data into the USB port of the PBX.
3. Set the PBX's System Mode Switch to the "SYSTEM INITIALIZE" position.
4. Turn on the PBX's power switch. The STATUS indicator will flash green.
Slide the System Mode Switch back to the "NORMAL" position.
The restore process will begin and the STATUS indicator will flash rapidly.
5. When the restoration process is completed, the PBX will restart automatically.
