Aironet 1600 Transmitter power: error

Under the 2.4ghz status I see:

Transmitter Power

error

Which i believe is the culprit for weak wireless and also choppy connection to AP.

attached is config

Also I'm using cisco power injector which says its non-cisco which it is!!

Help guys no one in cisco has answer they just send me to different people and now I'm HERE!!

John!

For the command, yes you need the MAC address. Enable CDP and issue a show CDP neighbor and see if the MAC address shows. If the AP is working fine, I personally would leave it alone. I'm not 100% sure if this will eliminate your issue. It's just an old school way of doing things that worked in the past.

Under each radio, you can set the power level. Try setting that first and see. Also what you can try for the power is to disable CDP on the ap. This should fix that issue. See the link below

Re: Aironet 1600 Transmitter power: error

I did everything upgraded firmware etc..

The issue is it is working fine but the Error message is because it cant see the Injector and says its a NON-CISCO which of course it is and labeled on the injector it is a cisco

but everything is working

i guess we can close this due to a minor glitch cisco end

Did you disable cdp on the access point?

Re: Aironet 1600 Transmitter power: error

Along with CDP you should also set the power inline. Is the power injector the one listed here?

Powering Options
? 802.3af Ethernet Switch
? Cisco AP1600 Power Injectors (AIR-PWRINJ4=, AIR-PWRINJ5=)
? Cisco AP1600 Local Power Supply (AIR-PWR-B=)


Caution When using the power inline negotiation injector override command, a power injector must always be installed to prevent a possible overload condition with an underpowered power source.

It is:

AIR-PWRINJ5=

Currently have CDP disabled, and what is the command for setting the power inline?

Re: Aironet 1600 Transmitter power: error

So i ran command:

ap(config)#power inline negotiation injector installed

Error: Command failed. No MAC address detected. Is CDP enabled?

I don't know the MAC of the injector as i'm not physically There, do I have to have the MAC address of the injector?
