Chapter Eleven: Software maintenance
The Avaya 3641/3645/6120/6140 IP Wireless Handsets use proprietary software
programs specified and maintained by Avaya. The software versions that are running on
the handsets can be displayed during power on by holding down the END button.
Software Version is also an option on the Config menu.
Avaya Customer Service or an authorized dealer will provide information about software
updates and how to obtain the software (for example, downloading from a website).
After software updates are obtained, they must be transferred to the appropriate
HTTP/TFTP server located on the LAN to update the code used by the wireless handset.
The handset allows over-the-air transfer of software updates from the designated server
to the handsets. The download function in the wireless handset checks its software
version every time you power on the handset, when the designated server is active. If
there is a different version available, the handset immediately begins to download the
update.
Upgrading handsets
After you obtain the software updates, you must transfer the updates to the appropriate
location in the LAN to update the code used by the handsets. In case of supplying a list
of HTTP server addresses via SSON or config files, ensure that you transfer the update
to all servers to avoid inadvertently downgrading code in case of a server outage.
Avaya 3641/3645/6120/6140 IP Wireless Handsets allow over-the-air transfer of
software updates from the designated TFTP or HTTP server to the handsets. The
downloader function in the handset checks its software version every time the handset is
turned on. If there is any discrepancy the handset immediately begins to download the
update.
Normal download messages
When the handset is powered on, it displays a series of messages indicating that it is
searching for new software, checking the versions, and downloading. The normal
message progression is:
Message Description
Checking Code
The handset is contacting the HTTP/TFTP server to determine if it has a newer
version of software that should be downloaded.
Erasing Memory
The handset has determined that a download should occur and is erasing the
current software from memory. This message also displays a progress bar. When
the progress bar fills the display line the erase operation is complete.
