These instructions include the procedure for upgrading the SBC SWe Lite to the latest software release for the following platforms:
Comply with the following Prerequisites:
Clear all outstanding alarms. To clear alarm(s), refer to Acting on Displayed Alarms.
Contact Ribbon Support for any problems you encounter during the software upgrade that you cannot resolve.
The Azure-based instance of SBC SWe Lite is initially acquired and deployed via Azure Marketplace. For a subsequent upgrade to the SBC SWe Lite, go to the Ribbon Support Portal - Download Center to download the latest compressed software image bundle (.zip ) that contains the upgrade file and upload it onto the SBC SWe Lite. Software upgrades are available for Ribbon customers current on maintenance. (This upgrade offering is established upon initial license purchase from Ribbon.)
Follow these steps for upgrading to the latest Azure instance of SBC SWe Lite:
USE OF KVM, VMWARE, AND PRE-8.0 HYPER-V IMAGES IN AZURE WILL CAUSE A SOFTWARE UPLOAD FAILURE!
Do not upgrade an Azure-based SBC SWe Lite instance with any image with the "kvm" or "esxi" characters in the filename. Images that include these characters in the filename do not operate in an Azure-based SBC SWe Lite instance and will result in SBC failure. Only use Hyper-V images that are labeled with the 8.0.1 release or later.
NOTE: Hyper-V releases earlier than 8.0.1 (such as 7.0.x) cause faulty SBC operation, and are not supported by Ribbon in an Azure context.
Follow these steps for upgrading an SBC SWe Lite deployed via KVM, VMware ESXi, or Microsoft Hyper-V.
The One-Step Upgrade method automatically upgrades the currently inactive partition, makes it active, and boots the SBC from the newly upgraded partition in a single step. Upon completion, the system is automatically redirected to the Login screen. Verify that you are booting from the new partition either by checking the active partition, or by Viewing the Software Version.
In the left navigation pane, click System > Software Upgrade.
Enter an optional Passphrase (refer to Using the Custom Passphrase).
Under Select File, click the Browse button and select the SBC SWe Lite image file you extracted from the downloaded software bundle.
Click OK to upload the new software. Do not close or navigate away from the browser window, or you may receive partial results. Throughout the upload process, the web interface displays update messages to indicate the progression of the upgrade, (sample screen displayed below). Once the upgrade is complete, the system automatically reboots.
Upon completion, the system automatically redirects to the Login screen.
Ensure the SBC SWe Lite has upgraded by verifying the running software version.
The Upgrading the Inactive Partition method upgrades and activates the new version without rebooting the SBC SWe Lite or interrupting active call services during maintenance hours.
In the left navigation pane, go to System > Software Management > Application Partitions.
Click Upload Software, located on the left side of the pane.
Under Select File, click Browse and select the SBC SWe Lite image file you extracted from the downloaded software bundle.
Clear the web browser cache before logging into the SBC SWe Lite.
