Cisco 3702i Access Point Flashing Red, Blue, Green Constantly

[nish]

I have deployed 30 Cisco 3702i access points on a Cisco 5508 Wireless LAN controller running IOS code 8.0.140.0.  Only 4 out of the 30 are flashing red, blue, and green constantly, but the other 26 are either solid green or solid blue like normal.  The weird thing is I see my client MAC address associated to one of the flashing access points, and is able to access the network fine.  Looks like a cosmetic issue, but would like to fix the flashing access points to be either solid green or solid blue like normal operation.  Does anybody know why this is happening?

I have attached a video of slow motion of the LED and a video normal speed.

Check the configuration of the AP.  Indefinite Flash is enabled.

Nish,

It looks like, it cycles through Cycles through RED, GREEN and OFF. That means, the AP is an universal AP which needs to get primed.

This youtube link shows the process of priming universal AP.

This document describe all the details about priming.

I hope this will help.

Chandana,

  The color cycle is RED, BLUE, GREEN, RED, BLUE, GREEN over and over.  There is no stop or pause between the colors.  It is constant switching of the LED colors.  As I mentioned above the AP with this affect works.

(my notes) Trying to find a lost AP?

Ssh to controller

Config ap led-state flash indefinite (to make it flash red green blue, indefinitely)
---------------

Config ap led-state flash disable (to turn off the flashing)

if the color cycle is slightly different the AP maybe having not enough inline power:

Cycling through blue, green, red, and off

General warning; insufficient inline power
