The LEDs on the AirPort Base Station (Dual Ethernet) provide status information through a series of blinking patterns. Taken in combination with the state of the base station, these patterns provide unique indications. See Figure 1.
The AirPort Base Station (Dual Ethernet) differs from the previous base station in the color of the status LEDs. The earlier base station uses multi-color LEDs (amber, red, and green). The AirPort Base Station (Dual Ethernet) uses a single LED color, white, to provide feedback.
