The new generation Cortex 360 units from Davicom are virtually “unbrickable” because the Cortex firmware can be re-installed from a USB image file.
The Cortex 360 also offers stress-free firmware upgrades. The dual-firmware memory slots allow users to roll back to the previous firmware version in case the upgrade creates problems with the current I/O configuration. Performing a firmware rollback recuperates the previous I/O configuration associated with the previous firmware version.
To perform a firmware rollback (Load Previous):
Connect to the Cortex 360 unit with a browser (Chrome recommended).
Go to System > Administration.
Click the Load Previous button.
The unit will reload the previous firmware version and its associated I/O configuration.
The unit will then reboot and start up with the previous configuration.
NOTE: The Load Previous procedure can also be done using front-panel buttons (refer to steps 1 to 5 from this article).
