Update Software On The Wlan Application Gateway 2246; Update Software On A Wireless Handset - Avaya Communication Server 1000 Installation And Commissioning Manual

Administration and maintenance
Caution:
Always ensure that only the latest version of software is on the TFTP Server and that earlier
software versions are deleted, moved, or renamed.
At startup, the WLAN IP Telephony Manager 2245 always uses TFTP, if configured in the
2245, to compare its software version with the version on the TFTP Server. If the versions
are different, the WLAN IP Telephony Manager 2245 downloads the software version from
the TFTP Server, even if it is an older version.
Lock the system
Always lock the WLAN IP Telephony Manager 2245 in the SVP-II Configuration screen before
updating the software. Locking the WLAN IP Telephony Manager 2245 prevents new calls from
starting.
Reset the WLAN IP Telephony Manager 2245 after the update is complete.
Important:
All calls in progress are terminated when the WLAN IP Telephony Manager 2245 is reset.

Update software on a wireless handset

With the WLAN system, you can perform over-the-air transfer of software updates from the
designated TFTP Server to the wireless handsets.
The downloader function in the wireless handset checks its software version every time the
wireless handset is turned on. If there is any difference in the software version, the wireless
handset immediately begins to download the update.
On a clear 802.11a/b/g channel, the download process takes one minute or less to complete.
If the TFTP Server cannot be reached at the time the wireless handset is powered on, resets, or
comes back into a WLAN service area, the wireless handset tries a few times to contact the
TFTP Server, and then gives up and uses the existing software.
If more wireless handsets are requesting TFTP service than the TFTP Server has ports
available, or if the TFTP Server is unreachable or unavailable, the wireless handsets try a few
times to reach the TFTP Server, and then continues to use the existing software. In other words,
it is not possible to guarantee that a wireless handset is using the latest software.
