Upgrade Using Boot Loader

To upgrade the Quantum Spark Appliance using U-boot (boot loader):

Note - In 1570 / 1590, Bootloader is supported only through the DMZ port and is not available through the LAN ports.

1. Connect to the appliance with a console connection (use the serial console connection on the back panel of the appliance), boot the appliance and press CTRL+C. The Gaia Embedded Boot Menu is shown.

2. Press 5 to select Install/Update Image/Boot-Loader from Network.

3. You are asked if you want to load the image manually from a TFTP server, or if you want to use automatic mode with a bootp server.

4. If you select manual mode, you are asked to fill in the IP of the Quantum Spark Appliance, the IP of the TFTP server, and the image name.

5. If you select automatic mode, the procedure starts automatically to search for the bootp server.

6. While in menu mode, press CTRL+C again to return to the Boot Loader menu.

   During the upgrade, the Power LED blinks blue to show progress. This takes up to a minute.

   When the upgrade is successfully completed, the Power LED is solid blue, and the appliance waits for you to press a key. Error in the upgrade process is indicated if the Power LED is red.
