Why this Cisco controller doesn't work with these Cisco APs?

This is using a brand new Cisco CISCO AIR-CT2504-K9 WLC to support few Cisco AiR-AP2702i-UXK9 APs. In CT2504 WLC web console, found that all these APs failed to operate and failed to grab IP allocated from CT2504 internal DHCP. I saw the AP2702i front LED blinking green and Red, but still, at the end failed to work. The question is does these type of AP can work along with CT2504?

I heard the these AP have to be kind of "air-provisioned" or "priming", are these true? How to make them work with CT2504?

Thanks in advance.

Or rather do a Autonomous to LWAP conversion? if so, how?
Craig BeckCommented:
First, a question...

What version of code do you have installed on the WLC?

The APs are Universal APs.  That means they can be used in any regulatory domain.  To get them working (assuming the version of WLC code supports the APs) you need to specify the country code.  This guide will help...

Hi both,

The front LED is blinking green, red, off, repeatedly. Attempt to do priming not possible as no SSID available to associate.
MichaelBalackAuthor Commented:
Neither can I use the console port and web console, as both do not work. I pressed the MODE button, but can't reset the config.
Craig BeckCommented:
Please tell me what version of code is on the WLC.

Also, are APs on a VLAN attached directly to WLC or are you routing the AP subnet to the WLC?
MichaelBalackAuthor Commented:
WLC is using

APs are on the same VLAN of WLC, in fact, this is a flat switch infrastructure, with only vlan 1.
Craig BeckCommented:
OK, you need to follow the manual provisioning instructions to get one AP configured then the rest of the APs will automatically provision.
MichaelBalackAuthor Commented:
Hi Craigbeck,

Ssid not available from that ap.
Craig BeckCommented:
No I know.  You need to configure it on the WLC then the AP will advertise it for use with manual provisioning.

You MUST follow the manual provisioning instructions, or it won't work.

Recognizing an Unprimed Universal AP

For an unprimed Lightweight AP:
On running the show ap summary command on the WLC, you see that the Country shows ‘UX’.
On running the show ap config general ap-name command on the WLC, you see that the Universal AP Prime Status is ‘Unprimed’.
In the WLC GUI, go to Wireless > Access Points > All APs, and click the AP name to see the details. In the Advanced tab, the Country Code is ‘UX’ and Universal Prime Status is ‘Unprimed’.
For an unprimed autonomous mode AP:
On running the show controllers d0 command, you see that the Carrier Set is ‘UX’. This information can be seen via the AP GUI also.
Preparing a WLC and Lightweight AP for Manual Priming

For manual priming to work, your smartphone must connect to the SSID broadcasted by the universal AP that needs to be primed. If your WLC already has access points with static regulatory domains joined, you need to isolate the universal AP in a separate AP group.
