What do the lights mean?

Tim Rohaly

The TINI board has four red LEDs mounted on one side, labeled CPU, LK, RX, and TX on the silkscreen. The CPU light indicates that the CPU is up and running. The other three lights monitor the Ethernet status. LK is lit when there is link-level connectivity over the Ethernet. This will not happen unless you have the TINI plugged in to an active 10BaseT hub. The LK light will go on after the CPU light during the boot cycle, and it should stay on as long as your board is connected. RX indicates that the TINI board is receiving data over the Ethernet. TX indicates that the TINI board is transmitting data over the Ethernet.
