CHAPTER 36 Upgrading the Device's Software

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.
You can obtain the latest software version files from AudioCodes website
(registered users only) at https://www.audiocodes.com/library/firmware.
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 team for assistance.
Currently, hitless software downgrade from Version 7.2.150 to an earlier version is
not supported (and the non-hitless method must be used).
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
- 659 -
Mediant 4000 SBC | User's Manual
Provisioning).
