Chapter 16 Updating the Software
132 Avaya P332GT-ML User’s Guide
Note: Please download both the new Avaya firmware and the new Embedded Web
Manager versions. Whichever version of the firmware you decide to run, always be
sure to match the correct firmware and Embedded Web Manager versions.
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-existant 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)
Note: 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_image <dummy_file_name>
<TFTP_server_IP_addr> <module_number>
Example:
copy tftp SW_image c:\versions\p330\p333t EW_image x 149.49.138.170 1
Note: Since file "x" doesn't exist the Embedded web image will not be downloaded.
