Using a Web Browser, navigate and log in to the main web page of your VX system.
Click on the Backup/Restore link on the left side menu under the System heading.
Click the Backup Settings button and save the file to your computer.

Download the update file

There are separate update files for VX Enterprise and VX Prime+.
Please take care to download the correct version for your system. If you are unsure which system you have, there is a logo in the top left corner of the main configuration web page. Although the update files are different, the update process is the same.

Click on the Firmware link on the left side menu under the System heading.
Click the Activate button next to the Slot to make it active.
Click the Reboot Now button that appears at the top of the page.

No additional warnings are provided. The system will immediately reboot.
