Updating software
Nortel Networks provides information about software updates. Download the
software updates from the Nortel Networks web site.
After the software updates are obtained from Nortel Networks, they must be
transferred to the TFTP Server accessed by the WLAN IP Telephony
Manager 2245.
Updating software on the WLAN IP Telephony Manager 2245
To update the software on the WLAN IP Telephony Manager 2245, reset it.
When the WLAN IP Telephony Manager 2245 starts up, it compares its
software version to the software version on the TFTP Server. The WLAN IP
Telephony Manager 2245 downloads the software from the TFTP Server if
the versions are different.
Locking 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.
Note: All calls in progress are terminated when the WLAN IP
Telephony Manager 2245 is reset.
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 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.
