NOTICE! The outlets should retain their state, however, it cannot be 100% guaranteed. Outlets turned on via script will likely turn off. In mission critical environments, we recommend preparing for the worst and disconnect any equipment that must not be power cycled at this time.
1. From the Main Menu, select the "Firmware Upload" link.
If there is no Firmware Upload listed, use the Reset button to clear protection bits*.
2. In the "Firmware Upload" page, press the Choose File button and select the '.sysupgrade file', then press the Upload button.
3. The update will take about 3 minutes. The page will try to reload and likely fail. Wait for about 30 more seconds, then try again.
