Cisco AIR-CAP2702I-UXK9 AP Status LED Issue - Green-Red-Off Cycle

[Zemherir]

Hello everyone,
I have a Cisco AIR-CAP2702I-UXK9 access point running firmware version 15.3(3)JK7, connected to a 5520 Controller with firmware 8.10.171.0. The access point successfully connects to the controller, obtains an IP address from the correct subnet, and clients can connect to the AP without any issues. Everything seems to be working as expected.

However, I noticed the status LED on the access point cycles through green-red-off repeatedly.
After some research, I found the following Cisco documentation:

https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-0/AP_Regulatory_Domain_DG/b_universal_AP_regulatory_domain_DG.html

This document suggests that this may relate to regulatory domain settings, but it’s quite outdated, and I’ve read that the configuration utility has been removed from the Android platform.

Does anyone know how to address this LED status issue?

@Zemherir 

 The reason could be due configuration. Try to disable It.

config ap led-state flash disable Cisco_AP

[Zemherir]

Thank you for your response. Unfortunately, this solution doesn’t fully address the root cause of the issue. Since these devices are deployed on-site, disabling the status LED might lead personnel to mistakenly believe the device is not functioning. For this reason, it may be more effective to resolve the underlying issue rather than applying a temporary fix.

[Flavio Miranda]

No. You did not get It. What I meant is, you can, via configuration make the AP Blink the LEDs. For many reason this can be done, for example to identify one AP among many. I did this a lot

 My suggestion is to make sure you accidentally did not enable this feature

 This command Will not chance the LED normal behavior, It Will only undo the configuration in case It was done by mistake.

[Zemherir]

I implemented what you said, but it appears to be already configured.

[Flavio Miranda]

Ok, this means the LED is not blinking due configuration. Let´s try to find out what else could cause this.

[Flavio Miranda]

@Zemherir 

As per the information below, on this case, the AP is awaiting to be priming and that´s why the LED is blinking. As you well told, the APP is no longer available so you probably need to accept this behavior.

 I believe this WLC is not under support anymore so probably Cisco TAC is not an option.

"

Boot up the universal AP.

For a universal AP awaiting priming, its status LED cycles through Red-Green-Off. For more information on the LED states, see AP Status LED States."

I followed and applied all the steps. I even tried using the Cisco AirProvision app by downloading the APK file, as it has been officially discontinued.Unfortunately, I wasn’t able to achieve the desired result.

[Flavio Miranda]

it is indeed very odd. I had to  do this once and it took me a day. But, if you have the APP then you can do this.

  Make sure you can get internet access while doing this.

 - Probably the AP does not get sufficient power.It can work but not with full capacity,

Hello,

As you suggested, I checked the power status and can see that it’s drawing 16.8W. It's connected to Port 32.

   - Power is good. You could either reboot the AP and post the full boot process here to get insights ; usually that is not possible for a remote AP anywhere in a building ; therefore do the same and just after boot connect to it with SSH and
issue the command show logging
(when doing this just after the AP has booted , most of the boot information is still available) ;==> look for errors , if any

[Zemherir]

I have the Access Point with me and a console connection is available. If I can fix this issue, I’ll bring over the other access points one by one and check them as well. The console output on the CLI screen is as attached.

[marce1000]

 - I don't see any problem with the boot sequence ; is AP available in the list of joined  APs on the controller ?

 M.

[Zemherir]

Yes, I can see it in the list of joined APs.
