A later firmware is available on the Cloud Helper Server. Click this icon to
display a What's New pop-up screen. You need a Firmware Upgrade
license to upgrade the firmware. If you do not have a license, Upgrade
Now is grayed out. If you have a license, click Upgrade Now to directly
upgrade firmware to the standby partition and have the ZyWALL/USG
reboot automatically so that the new standby firmware becomes the
running firmware. The previous running firmware becomes the standby
firmware.
Cloud firmware is being downloaded from the Cloud Helper Server. If you
select another partition or the local firmware upgrade icon, you will see
the following warning message.
When firmware is downloading, you can pause, resume, stop or retry the

Use this if you have already downloaded the latest firmware from the

browse to the location of the unzipped files.
