Under Select File, click the Browse button and select the SBC SWe Lite file you previously saved.
Click Upgrade.
Click OK to upload the new software. Do not close or navigate away from the browser window, or you may receive partial results.

(If you navigate to this view from another browser, it will also display the progress.) Once the upgrade is complete, the system automatically reboots.
Upon completion, you will be 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, go to System > Software Management > Application Partitions.
Click the Upload Software link located on the top right hand side of the pane
Under Select File, click the Browse button and select the SBC SWe Lite file you previously saved.
On the partition page, verify the Last Upload Status associated with the inactive partition is listed as Success.
Throughout the upload process, the web interface displays update messages to indicate the progression of the upgrade of the inactive partition, as shown below. (If you navigate to this view from another browser, it will also display the progress.)
Under normal conditions, a typical upgrade takes about 5 minutes. During the upgrade process, the remaining time estimates in the different steps becomes more accurate as the process progresses.
At this stage, the inactive partition is upgraded to the the new software without rebooting the SBC SWe Lite and without interrupting active call services. To set as the active partition, refer to Setting the Active Partition.
