Power on

One convenient way to power up your Carambola is by connecting it to a USB power source (e.g. your computer) by using a USB to mini USB cable. Alternatively, you may connect it to a 5V 0.5A power supply. Both Ethernet ports should light up upon powering and will require at least 30 seconds to boot.

Now that we powered Carambola on, let’s connect it via lan port. Configure your computer's network interface with IP address and netmask. Make sure that other devices on your network are not using this subnet! If everything is done correctly you should be able to reach Carambola via the default IP address of
