Download New Version without Overwriting Existing Version

Sometimes it is desirable to upgrade to a new software version while retaining the option of
booting from the previous version. The following process copies the previous version from
memory Bank B to Bank A, and download the new version to Bank B. This process
accomplishes the following:
• prevents the embedded web image-file from being downloaded into Bank A - by
providing a non-existent file name for the Embedded Web image file.
• preserves the old version in Bank A
• allows the user to boot from either Bank A or Bank B (i.e., using either the old or new
software version)
In normal operation, the Embedded Web file should be copied to Bank A, and the new
software version should be downloaded to Bank B. This process copies the old software
version to Bank A and the new software version to Bank B, and allows the user to boot from
either version via the set boot bank command.
To perform this process:
copy tftp SW_image <new_ver_file> EW_archive <dummy_file_name>
<TFTP_server_IP_addr> 1
Example:
copy tftp SW_image c:\versions\W310\w310 EW_archive x
149.49.138.170 1
Since file "x" doesn't exist the Embedded web image will not be downloaded.
