I bought a Cisco Aironet AIR-AP1231G-A-K9 off of ebay and am having issues with it.
The first and most alarming issue is the cycling of the status lights. I read the manual and it does not show that as a possible state.
Here is a video of the status lights -> https://www.youtube.com/watch?v=ubuBkHCuwWg
It does pull an IP address via DHCP on my Sonicwall, but is unreachable via web browser. I pinned out my own console cable, and nothing comes up over the console when done in accordance with the manual.
I tested the power supply and it is making 47.8vdc, and makes 47.8vdc when under load (connected to the Aironet).
It doesn't appear to be broadcasting an SSID, but of course if it is, it would be easy to miss since I don't know what it is (used unit).
Bad unit?
Thanks for your time.

The continuous blinking lights, although undocumented, were caused by the Aironet not being able to reach the WLC (wireless lan controller). Long story short, it was in LWAPP mode, also known as lightweight mode where it connects to a controller. The key is to get it back into "autonomous mode" (to use as a standalone WAP) via a change in firmware with tftp (see below).
The next issue is that the Cisco pinout for RJ45 to DB9 is incorrect - pin 6 and 3 need to be swapped on the RJ45 to get the communication working.
Lastly, I used the following steps to change the firmware:

Follow these steps to revert from LWAPP mode to autonomous mode by loading a Cisco IOS release using a TFTP server:
