Upload the Firmware File

This can be done either using a USB memory stick, or FTP if the Sentinel is accessible remotely via the management interface.

USB

If using USB copy the downloaded Sentinel Firmware file onto a memory stick and insert the memory stick into the Sentinel’s USB Host Port. Select System > File Management and copy the file to an appropriate location on the Sentinel’s internal memory.

FTP

If using FTP upload the file to the Sentinel’s internal memory.

Confirm the versions shown in the popup, and select Yes

Do not shutdown or reboot during this update.
