This is what I tried to resolve this problem so far:
- Connected back to the Controller. The reverse telnet does not work from the controller either on some AP's. Other AP's work fine.
- Tried different speeds.
- POE and without POE through the Y cable.
Suggestions for further troubleshooting? Is there a danger that POE may go through to the serial pins and burn the circuitry?

Are you getting power to the AP by a switch, or power injector?
The issue is (most)PoE switches put power and data inline freeing 4,5,7,8 for serial over Ethernet connectivity.
Certain switches (matrix b) and usually all PoE injectors put power over the unused pair 4,5,7,8
A "Y" breakout adapter wont work here, you need the SPOE-4 from Aruba , and also need to be on the other side of the injector (AP side). The SPOE-4 removes power from 4,5,7,8 and puts it inline with data over pairs 1,2,3,6.
