The rear LEDs of my airport extreme base station (i.e. the LEDs near the connections) are simultaneously blinking (once per second) and the front LED is off. What does this mean?
Unfortunately, this almost always means that the internal power supply of the AirPort Extreme has failed, and the device will need to be replaced.
Take the AirPort to an Apple Store or Apple Servicer....if you have one near you....to let them take a look and go over your options with you.
