Manage firmware updatesusing Digi Remote Manager
If you have a network of many devices, you can use Digi Remote Manager Profilesto manage
firmware updates. Profiles ensure all your devices are running the correct firmware version and that
all newly installed devices are updated to that same version. For more information, see the Profiles
section of the Digi Remote Manager User Guide.
Certificate management for firmware images
The system firmware filesare signed to ensure that only Digi-approved firmware load onto the device.
The IX20 device validates the system firmware image as part of the update process and only
successfully updates if the system firmware image can be authenticated.
Downgrading
Downgrading to an earlier release of the firmware may result in the device configuration being erased.
Downgrading from firmware version 22.2.9.x
Beginning with firmware version 22.2.9.x, the IX20 device usescertificate-based communication for
enhanced security when connecting to Digi Remote Manager. If you downgrade your firmware from
version 22.2.9.x to version 21.11.x or previous, your device will no longer beable to communicate with
Remote Manager.
