802.3af to power AP2800/3800

[Wei Kwong Ong]

Hi, what is the consequences to power on AP2800/3800 by 802.3af 15.4W? There is a note from the link below saying that:

"Note: If the AP2800 and AP 3800 are powered from an 802.3af power source the LED will cycle though the colors and the radios will be disabled" 

What does it mean? What radio will be disabled?

Hi Scott,

hope you are doing well.

I have one question regarding Licenses.

I have a WLC55008 (active/standby hot) with 75 AP licenses.

if the number of APs exceed 75, the controller will allow the exceeded number of APs to join?? and if so, the extra number of APs will function properly??

thanks,

Haitham Jneid

Just to add... If you don't have 802.3at, then don't purchase these AP's. You would have to purchase power injectors like AIR-PWRINJ6= or other 802.3at power injectors by other companies. Basically like Sandeep mentioned, you will be able to boot the AP's up and never get the radios in a working state.

For a universal AP in the process of getting primed via Cisco NDP, its status LED blinks Blue, White, or Amber depending on which AP series it is. For more information on the LED states, see AP Status LED States.

The process of automatic priming is as follows:

1. Upon boot up, a lightweight universal AP joins the wireless LAN controller (WLC) just like any non-universal lightweight AP.

2. The universal AP, while continuing to stay connected to the controller, will be scanning the 2.4 GHz and 5 GHz band for NDP messages from neighboring universal APs.
NDP messages are sent, by default, every 60 seconds. Therefore, a newly booted AP may need more than a minute after successfully joining a controller, before detecting and using the NDP messages from an already primed Universal AP in the neighborhood.

3. If automatic priming is available, then the universal AP receives country information, reboots and rejoins the controller as a primed AP. To ensure that your AP is properly primed, see Checking whether the AP is Successfully Primed.
If automatic priming is unavailable or does not work, the lightweight AP waits for you to manually prime it. To proceed with manual priming, go to Step 2 in the Overall Workflow for Priming a Universal AP.
