One of my customers gave me an old AIR-AP350 series access point.

When you power it on it gives 3 solid amber lights, then flashes 3 solid red lights, then 3 solid green lights and then all activity stops as far as the indicator lights go. I don't get any response at all through the ethernet port and I get nothing through the serial port.

Is there anything I can do with this or is it junk?
