30.3 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 devices 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) device loads the .cmp file.
2. The active device sends the .cmp file to the redundant device.
3. Both active and redundant devices install and burn the file to flash memory with a
reset. In other words, no HA switchover occurs.
Hitless Upgrade: The devices are upgraded without disrupting traffic (i.e., current
calls are maintained). The process is as follows:
1. The active (current) device loads the .cmp file.
2. The active device sends the .cmp file to the redundant device.
3. The redundant device installs and burns the file to its flash memory with a reset.
The redundant device now runs the new software version.
4. An HA switchover occurs from the active to redundant device. Therefore, current
calls are maintained and now processed by the previously redundant device,
which is now the active device.
5. The previously active device (now in redundant mode) installs and burns the file
to its flash memory with a reset. Therefore, both devices now run the new
software version.
6. An HA switchover occurs from the active device (i.e., the initial redundant device)
to the redundant device (i.e., the initial active device) to return the devices to their
original HA state. Only the initial redundant device undergoes a reset to return to
redundant state.
