AIR-LAP1131AG-C-K9 Radio 802.11b could not be enable

[ghoppersepp]

I've a 2106 WLC and the software is upgrade to 7.0.220.0. There are 3 APs with external power adapter work normally on it.

Here is the problem:

There is another AP with external power adapter has join the the WLC successfully. But it can not enable the radio 802.11b. Following is the error message on CLI, What could be the reason and solution for it? Thanks a lot!

(Cisco Controller) config>802.11b enable AP001d.a1ef.b5f4

Cisco AP has not enough in-line power to enable radio

[Surendra BG]

Go that AP from the WLC

WLC GUI >> WIreless >> AP >> AP Edit >> Advanced >> We see Power inline or power injector..

Please fiddle around this and see if that helps!!

It is still not work.

Following is my step:

     1. I selected "Power Injector State"

     2. There is 2 selection for "Power Injector Selection". "installed"and"override". I've tried them both.

Please help~

Thank you!

I'll try to get console log later because I could just access the AP remotly at this moment.

By the way, I've tried to replace this AP with another one which could work normally in another room. It doesn't work as the first one. Is it possibel for the switch's prolbem?

Thanks a looooooooot!

[Leo Laohoo]

Depends.  One of the few times I've seen the radios going down is when you combine power injector to, say, a 2940/2950 switch.  Not certain until you console and reboot the WAP.

Your output doesn't have anything unusual.
