AP 1142N low power

[karthikeyan gopinathan]

hi

i connected a new Cisco 1142n access points to a cisco 3560E 24 port POE switch. the AP is getting only lower power which is 14.5 but the switch is capable of deleivering 15.4 watts. i checked the console messages in the AP and it is giving the error message 

CDP_PD-2-POWER_LOW: All radios disabled

there is an other same model AP connected to the switch and it is getting full power

please let me know asap because i am in middle of a project

Thanks

In the AP config, you can go in and tell it that it's getting pre-standard power.  Optionally, you can disable CDP on that port as well.

HTH,

are you asking me to login to AP and set a prestandard power

please explain me how to do it

[Stephen Rodriguez]

for an IOS AP,

conf t

config power inline negotiation prestandard source

If this is a WLC installation, it's in the AP config

HTH,

but in the switch if i type in the command show power inline i see this AP drawing only 14.5 watts..there is another AP connected to this switch which is drawing enough power 15.4 watts

[Stephen Rodriguez]

that can happen. Depends in how much power the switch tells the AP is available during the CDP/FLP negotiation

hi

can you let me know how to make the controller upgrade the image of a new Cisco AP connected.

On the Cisco switch, please post the output to the command "sh power inline".
