*** For the real correct answer, see grobsons's reply about the power supply ***
Hi,
I am a total noob and have a brand new AP 1852i with Express Mobility. After going through the wizard, I can join the created WLAN and access the management URL. The AP is powered by an 802.af injector device and the data sheet - as I understand it - says this is supplying sufficient power (15.4W) for the AP, for the device will shut down some functions (AUX, USB) when only getting 15.4 W.
Still, the LED is cycling through red-green-amber-off and I am soooo keen to see a steady green
Can someone help me?
Kind regards
Carsten

If everything is working, then maybe upgrade/downgrade. I thought I saw something about that being a bug but will have to try to dig that up.

You can SSH to the controller and issue the following command to disable the LED if you want.
config ap led-state disable

You need to check the model number of the AP. If the AP model is AIR-AP1852I-UXK9, then you need to prime the access point to define a regulatory domain. See the following link:

You will need to download an app for your iphone/android in order to prime the AP

Thanks for answering.
The model number is AIR-AP-1852I-E-K9, so I guess it's already primed, isn't it?
It came with a CAPWAP image and I flashed it to Express Mobility 8.2.100 via TFTP.
Is your answer still valid for this model and my doing?

The AP you have is not a Universal AP (UX) so you don't need to prime. Have you followed the guide to configure Mobility Express?

Yes, I did. Apart from the cycling LED everything is working fine.
I read the Getting Started part of the user guide again and would pretend, that I followed exactly. The AP icon under Access Point Administration in ME shows an attached P, meaning primary AP. It's my only AP and there is no controller in my network.

Thank you for your effort.
I think I'll leave it this way, for it's only blinking light. Function ist there, form will follow ;-)
Kind regards

+1 for this - better than blinking. Only steady green will ace this out.
Kind regards

Take a look at this... again, as long as the AP's are not AIR-AP1852I-UXK9 you are fine.

although marked as solved, from the HW installation guide
cycling through red, green, amber, and off -> General warning; insufficient inline power
so you will need another power injector to supply sufficient power and keep the LEDs steady

It will cycle through the colours because it is connected to 802.3af power. If it is supplied 802.3at the cycling will stop.

And yes,
the real correct answer goes to grobson!
Thanks for pointing me to this. As soon as I supplied 802.3at power, the LED glowed steady green.
