Enter a header name for the configuration data backup file and
press Enter. Enter up to 128 characters of text, including spaces,
carriage returns, and line feeds.
If you enter more than 128 characters, the system exits text entry
mode and responds with R>. If you do not want to enter text, press
Enter.
The system responds with R> , to indicate that it is ready to continue.
You must complete the next step within 2 minutes or the system times
out. If a timeout occurs, return to Step 5 and retype the XBK command.
To receive the configuration database file, use the Xmodem protocol.
The file arrives in binary format.
For information about receiving files, see the manual supplied with
your communications software package.
Wait for the file transfer operation to end. File transfer time depends
on database size and baud rate. When the file transfer completes
sucessfully, the system responds OK.
If the file transfer fails, the system responds with one of the following:
Some transferring data is invalid. Data transfer is not
BKP0003
attempted.
Corrective action: Repeat the backup procedure from
the beginning (EDD).
The data transfer was interrupted by a system timeout
BKP0008
or by a line problem, such as excessive noise.
Corrective action: Repeat the procedure from Step
5 (XBK).
To verify the CCBR backup, type XVR. Wait for the system to respond
with the R> prompt.
The XVR command sends the backed-up file to the system and
compares it with the original configuration data. This ensures the
integrity of the backed-up file.
With the communications software on the computer, use Xmodem to
send the backed-up file to the system for a comparison.
The system displays the character C every 3 seconds until the file is
sent. The file transfer must finish before the character C appears 20
times (approximately 1 minute) to avoid a system timeout.
Following is an example of what can appear on the screen:
