BaCkUP FUNCTION

9.1 Data Cloning
9.1.1 General description
Data cloning is a function that backs up user data, setting data and SRAM data into a USB
device and also restores these data into the equipment.
This function backs up or restores the data of the same equipment (same serial number), and is
performed in the following cases.
- When the SYS board and the SRAM board are mistakenly replaced at the same time
- When the SRAM board is replaced
Notes:
The SYS board and SRAM board should never be replaced together.
9.1.2 Precautions
• When the ADI-HDD is initialized or replaced, back up the SRAM data afterwards.
• It is assumed that data cloning is to be performed when equipment is installed or options are
installed. If the address book has been registered, do not perform restore. Registered / set
data are lost.
• The USB device for the data cloning must meet the following conditions. A data cloning
operation with any devices other than the following will not be guaranteed.
- A combination USB device with a flash memory (to be connected directly to the USB port)
and its capacity is 1GB or more.
- A device compliant with the following specifications established by USB-IF (USB
Implementers Forum)
Class number:
Sub-Class number:
Protocol number:
The USB device should be formatted in the FAT or FAT32. (Correct operation cannot be
guaranteed if it is formatted in NTFS/exFAT.)
- Most of the common USB device are compliant with the above specifications and are
therefore applicable to this data cloning. However, most of these devices were originally
developed to be used in an environment for PCs (e.g. Windows or Macintosh) and thus
operations exclusively with this equipment have not been fully guaranteed. Therefore, the
user must thoroughly check in advance whether there will be any problem in operating with
this equipment when adopting one of these devices.
• The USB device compliant with both USB 1.1 and USB 2.0 can be used for this data cloning.
• Data cloning with any storage devices other than a flash memory (e.g. USB-connectable
memory card reader, CD/DVD drive, hard disk) will never be guaranteed. Therefore never use
them for this operation.
• Be sure to unplug the LAN cable and Fax line before data are backed up / restored. Also, do
not use the RADF and open the cover, drawer, etc. during the data cloning.
• Data can be backed up / restored only for the same model and version. If the version is
different, update the firmware and back up / restore data in the same version.
• Restore data to equipment which has the same options as when the data are backed up.
• Delete the backed up data in the USB device after the data cloning.
