Problem with wireless Accesspoint 1252AG-E-K9

I have a wlan network with 4404 controller,1252 access points and WCS. My acess points are powered through POE. Now when i checked the alarms in my WCS i saw an alarm saying " AP X associated with controller X is drawing low power". My switches are catalyst 3750G switches and they support maximum of 15.4 W inline power. Is there any way to solve this issue other than connecting a power injector?. And please advise me what are the problems that i will face if the access points are running on low power?.

What is the firmware of your WLC?  Firmware 6.X allows the 1250, with both radios operational, to be powered up with 15.4W.  The "cost" is lower MCS rates.

My WLC version is 6.0 . The access points are up and running. But the typical error comes again n again in the WCS. If the power is low will there be any effect in signal strength??... Pls reply....

Yes.  Some of your higher MCS rates are disabled.  Basically, you can get both radios functional but the "footprint" of the radio signals is lower.
