  • The devices are online and reachable.

  • Devices have a stable internet connection.

  • The target firmware version is available.

  • You have Administrator privileges.

  • Devices have sufficient power throughout the upgrade.

3. Navigate to Bulk Firmware Upgrade

Important Notes

  • Firmware upgrades typically take 10–15 minutes per device.

  • Devices are upgraded in the following order:

    1. Access Points

    2. Switches

    3. Routers

  • Offline devices will automatically begin upgrading once they reconnect.

  • Do not power off or disconnect devices during the upgrade process.

  • Ensure devices remain connected to the internet until the upgrade completes.

13. Viewing Upgrade History

Navigate to:

Firmware → Most Recent Upgrades

  • The Most Recent Upgrades page provides a history of the latest firmware upgrades performed across the network. It allows administrators to verify whether the upgrade was completed successfully.

  • The table displays the following information:

  • Device Name – Name of the upgraded device.

  • MAC Address – Unique hardware address of the device.

  • Device Type – Type of network device (Router, Switch, Access Point, etc.).

  • Firmware Version – Displays both the previous firmware version and the upgraded firmware version.

  • Last Upgraded – Indicates when the firmware upgrade was completed.

  • Firmware Status – Displays the result of the upgrade, such as Success or Failed.

Expected Result

After saving the configuration:

  • The firmware upgrade is scheduled successfully or starts immediately (depending on the selected option).

  • Devices begin upgrading according to the selected schedule.

  • Upgrade progress and status can be monitored from the Most Recent Upgrades section.

  • Once completed, devices will report the newly installed firmware version.


Best Practices

  • Verify all devices are online before scheduling an upgrade.

  • Ensure devices have a stable internet connection.

  • Upgrade during a maintenance window to reduce service disruption.

  • Confirm the target firmware is compatible with all selected devices.

  • Review the release notes before selecting a firmware version.

  • Monitor upgrade status after scheduling.

  • Validate device connectivity and functionality once the upgrade completes.

Summary

The Firmware Bulk Upgrade feature provides a centralized way to upgrade firmware across multiple devices and networks. Administrators can filter devices, review existing firmware versions, choose a target firmware version, and either perform the upgrade immediately or schedule it for a later time. The feature also offers tracking through the Schedule and Most Recent Upgrades tabs, making firmware management more efficient and easier to monitor.
