802.11A radio disable and down

[Chieu Dinh]

I changed the role from Installation mode to Non-Root bridge then the Software is disable and Hardware is down in 802.11A radio. How do I enable it again without reset to factory?

Thanks

[Leo Laohoo]

Attach a console cable to the WAP and reboot.  I want to see the complete bootup process to determine as to why the radio is disabled.

Have you tried the command:

int dot111

no shutdown?

[Chieu Dinh]

Thank you for response. I did try the no shutdown command but it is still disable.

Here is my config

I can't input the power local and power client from the command line. I assumed it is running MAX.

Thank you very much

Those power commands "client/local" are related to "transmit" power, not the power necessary to "bring online" the radios of your AP.  It "seems" like you may not be drawing enough power, however you said the radio was "up" until you set the station-role to "non-root"?

Also, your outputs are regarding your 2.4 (d0) radio, but your post shows (802.11a radio down), so which is it?  Would you be able to post the entire run-config output?

Also, how are you powering this access point?  A POE switch, Injector, etc?

If POE, post the following, and specify which port your AP is in

#show power inline
#show cdp neighbor detail

If Injector/Adapter, please specify the exact model/part number.

Also, leolaohoo's request for the boot output would be nice too

[Chieu Dinh]

So out of curiosity.  Are you using this AP for a bridge or just for client access?

>>>> I am using this bridge as a non-root bridge. The root bridge is online near by less than a 1mile.

a Non-root goes 'reset/down' if it doesn't detect a parent. 

>>>>> So it means the 802.11A interface will be down until it can see a parent which is the root bridge?

Those power commands  "client/local" are related to "transmit" power, not the power necessary  to "bring online" the radios of your AP.  It "seems" like you may not be  drawing enough power, however you said the radio was "up" until you set  the station-role to "non-root"?

>>>>>Yes. The interface is up in the install mode until I set to non root bridge then it goes down.

>>>>> I am using power injector AIR-PWRINJ-BLR1

If POE, post the following, and specify which port your AP is in

#show power inline

If Injector/Adapter, please specify the exact model/part number.

So out of curiosity.  Are you using this AP for a bridge or just for client access?

If it's just for client access then:

station-role root

a Non-root goes 'reset/down' if it doesn't detect a parent. 

Can you share the dot11 ssid config?

Steve

[Stephen Rodriguez]

can you also post teh config of the root bridge?  What type of antenna are you using, and what ports do you have it connected to?  What type of AP are these?

Steve

[Chieu Dinh]

Hi Steve

I am setting up the new Bridge 1400. I did some testing with the default configuration. The 802.11A interface is down on the hardware and disable on the sofware when I selected the non-root bridge. When the first time I change the IP the bridge interface is still up and enable until I selected the non-root bridge and apply, it went down.

Thank you very much

[Leo Laohoo]

Attach a console cable to the WAP and reboot.  I want to see the complete bootup process to determine as to why the radio is disabled.

[Chieu Dinh]

I want to get the boot process to show you but this power injector and this bridge can not attach to the console. It is only run with the straight through cable.

Thanks
