Cortex 360 Firmware Upgrade and Rollback Procedures

The new generation Cortex 320/360 units from Davicom are virtually “unbrickable” because the Cortex firmware can be re-installed from a USB image file.

The Cortex units also offer 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.
