Preparing for Firmware Upgrade

Before performing a firmware update to the system, be sure to download the correct VOS. For more information, refer to Ribbon Support Portal - Download Center .

When performing a firmware update, refer to this  Knowledge Base Article  for instructions on creating the correct directory structure on your local FTP server to allow the system to perform a local firmware update.

Caution

When you update your software, telephone services are unavailable for several minutes. It is therefore advised that upgrades be performed during a maintenance window when telephone traffic can be interrupted.

Before you Begin

  1. It is recommended that you reboot the EdgeMarc before performing an upgrade. The reboot will ensure that enough dynamic memory is available to handle the upgrade process. Refer to  Reboot the System for more information.

  2. Check the System Information page to make sure there are no active calls in the Number of Active Streams field. Choose Admin > System Information and refer to View System Information.

Where do I Download new VOS Firmware?

VOS firmware is available on the  Ribbon Communications Support Portal . For more information on how to download the software, refer to  Ribbon Support Portal - Download Center.

The system automatically restarts after the new image has been loaded. Once the upgrade process has completed, verify that the new firmware version number is displayed on the Admin > Upgrade Firmware page.
