Note:
•
You can obtain the latest software files from AudioCodes Web site at
http://www.audiocodes.com/downloads.
•
When you start the wizard, the rest of the Web interface is unavailable. After the
files are successfully installed with a device reset, access to the full Web interface
is restored.
•
If you upgraded your firmware (.cmp file) and the "SW version mismatch" message
appears in the Syslog or Web interface, your License Key does not support the
new .cmp file version. If this occurs, contact AudioCodes support for assistance.
•
To upgrade the device from any earlier version to 7.0, do the following:
1) Delete core dumps from the redundant device through CLI (Telnet). Core dump
deletion can take up to 10 minutes.
2) Perform a manual switchover from active to redundant.
3) When the system is operational again, delete core dumps from the current
redundant device through CLI (Telnet). Core dump deletion can take up to 10
minutes.
4) Start the Hitless Software Upgrade procedure.
•
Instead of manually upgrading the device, you can use the device's Automatic
Update feature for automatic provisioning (see ''Automatic Provisioning'' on page
661).
The following procedure describes how to load files using the Web interface's Software
Upgrade Wizard. Alternatively, you can load files using the CLI:

cmp file:
copy firmware from <URL>

ini or Auxiliary file:
copy <ini file or auxiliary file> from <URL>

CLI script file:
copy cli-script from <URL>

HA devices:
•
Hitless Software Upgrade:
# copy firmware from <URL and file name>
•
Non-Hitless Software Upgrade:
# copy firmware from <URL and file name> non-hitless
If you load the firmware file through CLI, when you initiate the copy command a message is
displayed in the console showing the load progress. If other management users are
connected to the device through CLI, the message also appears in their CLI sessions,
preventing them from performing further actions on the device and disrupting the upload
process. For more information, refer to the CLI Reference Guide.

To upgrade the device using the Software Upgrade wizard:
1. Make sure that you have installed a License Key that is compatible with the software
version to be installed (see ''License Key'' on page 641).
2. It is recommended to enable the Graceful Lock feature (see ''Locking and Unlocking
the Device'' on page 622). The wizard resets the device at the end of the upgrade
process, thereby causing current calls to be untimely terminated. To minimize traffic
disruption, the Graceful Lock feature prevents the establishment of new calls.
3. It is recommended to backup the device's configuration to your computer. If an
upgrade failure occurs, you can restore your configuration by uploading the backup file
to the device. For more information, see ''Configuration File'' on page 659.
