Software Upgrade Wizard

The Web interface's Software Upgrade Wizard lets you easily upgrade the device's
software version (.cmp file). The wizard also provides you the option to load other files
such as an ini file and Auxiliary files (e.g., Call Progress Tone / CPT file). However, loading
a .cmp file is mandatory through the wizard and before you can load any other type of file,
the .cmp file must be loaded.
The wizard can also upgrade devices set up in High Availability (HA) mode. You can
choose between two optional HA upgrade methods:

System Reset Upgrade (non-Hitless): Both the active and redundant blades are
upgraded simultaneously. Therefore, this method is traffic-affecting and terminates
current calls during the upgrade process. The process is as follows:
1. The active (current) blade loads the .cmp file.
2. The active blade sends the .cmp file to the redundant blade.
3. Both active and redundant blades install and burn the file to flash memory with a
reset. In other words, no HA switchover occurs.

Hitless Upgrade: The blades are upgraded without disrupting traffic (i.e., current calls
are maintained). The Hitless Upgrade method operates as follows:
1. The active (current) blade loads the .cmp file.
2. The active blade sends the .cmp file to the redundant blade.
3. The redundant blade installs and burns the file to its flash memory with a reset.
The redundant blade now runs the new software version.
4. An HA switchover occurs from the active to redundant blade. Therefore, current
calls are maintained and now processed by the previously redundant blade,
which is now the active blade.
5. The previously active blade (now in redundant mode) installs and burns the file to
its flash memory with a reset. Therefore, both blades now run the new software
version.
