Upgrading the firmware
When available, gateway firmware upgrades will be automatically pushed
to your device via Auto Configuration Server (ACS). That said, in case of
ACS outage, this feature provides a way to upgrade the firmware
manually.
To upgrade the firmware, you must first obtain an official build package
that comes in the form of a file with the .tar extension; for example:
HB5GGW_R200300B70T0101E0618.tar.gz
1. Save the build package to a computer that's connected to the
gateway via Ethernet or Wi-Fi (hereafter referred to as the
management computer).
2. Log into the web GUI using admin credentials.
3. From the main menu, select System.
4. From the System menu, click Upgrade.
You are prompted to drag-and-drop or browse for the file.
5. Locate the .tar build package and open it.
6. Once the file is loaded, click Upgrade.
NOTE
Do not close the web browser or disable gateway power during the
upgrade process.
