Paul, Did you measure the voltage with the Airport connected to the POE? Under load, the resistance of the CAT5 cable is probably introducing a voltage drop of around 2 Volts. This assumes one amp of current on a POE that uses a pair of unused conductors for each polarity. The resistance of a CAT5 conductor is about 30 ohms per thousand feet.
You might consider buying 75 feet of 14 gage lamp cord or ourdoor extension cord wire. Splicing it into the AP's power feed will reduce the voltage drop to around 0.5 volt. The Airport may tolerate the half volt drop.

I have about 75ft of cat5 running to it. When plugged in to POE the 3 LEDs blink red a couple times and you can hear a very high pitched tone. Then nothing. The voltage there measures 14.4V with correct polarity. If the wall wort is plugged directly into the airport it works normal. Does this sound like too long of a cat5 run? -- general wireless list, a bawug thing <http://www.bawug.org/> [un]subscribe: http://lists.bawug.org/mailman/listinfo/wireless -- general wireless list, a bawug thing <http://www.bawug.org/> [un]subscribe: http://lists.bawug.org/mailman/listinfo/wireless
