The RJ-45 port LEDs on the RP indicate:

•Which Flash memory card slot is active.

–Each LED lights when its corresponding PCMCIA slot is accessed (SLOT 0 and SLOT 1).

•Which Ethernet connection is in use.

–4 RJ-45 Ethernet port activity LEDs indicate link activity (LINK), port enabled (EN), data transmission (TX), and data reception (RX).

•What is occurring on the Ethernet interface.

–2 Ethernet port-selection LEDs (labeled PRIMARY) identify which of the Ethernet connections are selected. Because both ports are supported on the PRP, the LED on port ETH0 is always on. The LED on port ETH1 lights when it is selected.
