Before you begin a cellular modem firmware upgrade

Review the following considerations:

  • DAL OS firmware version

    The cellular modem firmware methods for upgrading one or many routers vary based on the DAL OS firmware version running on those routers.

    For DAL OS 24.9 or older

    For DAL OS 24.12 or newer

    One Digi router at a time:

    • DAL OS Web UI

    • DAL OS CLI

    • DAL OS scheduled maintenance

    One or more Digi routers at the same time:

    One or more Digi routers at the same time:

  • Device-specific user guides

    Make sure to have your device-specific user guide handy as some of the procedures or information you may need are referenced there. Find the hyperlink for your router in the dropdown.

  • Verify network connectivity

    Confirm the Digi device has a stable internet connection to download the firmware update.

  • SIM card

    Ensure that there is a SIM card in the router or the Digi CORE plug-in LTE modem, or disable SIM failover. See "Configure a Wireless Area Network (WWAN)" topic in your device user guide.

  • Modem model

    If you are not planning to use Digi Remote Manager to perform this modem firmware upgrade remotely, you will need to know the model of the modem that is in or attached to your Digi device in order to download the proper modem firmware and perform the upgrade locally.

  • Review firmware and software changes

    To see the latest news and to understand the changes, improvements, and potential impacts of those changes, see the What's new in Digi Remote Manager and DAL OS.

  • Backup the DAL OS router configuration

    Save your current device configuration in case you need to restore settings after the update.

  • Schedule downtime

    Plan the update at a time that minimizes disruption, as the device may reboot during the process.

  • Power and battery backup

    Ensure the device has a reliable power source to prevent interruptions during the update

  • User access and permissions

    Verify you have the necessary administrative access to perform the update via the DAL OS web UI or Digi Remote Manager.
