Hi to All,

Can any one tell me why AIR-AP2802i-A-K9 cannot achieve POE full power went connected to Cisco switch WS-C2960S-48FPS-L with software version 15.0(2a)SE9.

WS-C2960S-48FPS-L power inline was already set to static 30 watt.

But when we try to connect AIR-AP2802i-A-K9 to switch WS-C2960S-24PS-L with software version 12.2(55)SE3 and it was able to achieve POE full power.

The WS-C2960S-24PS-L supports

The WS-C2960S-24PS-L supports up to 12 ports on 802.3at. Make sure CDP is enabled and look at the console of the AP while rebooting the AP.

Then why AIR-AP2802i-A-K9 were able to achieve PoE/Full Power when it was connected to WS-C2960S-24PS-L with software version 12.2(55)SE3 and both radio was up.

But when it was connected to WS-C2960S-48FPS-L with software version 15.0(2a)SE9. Power Status was PoE/Medium Power(15.4) and both radio was down.

I don't know. Do you have a lot of PoE devices connected to that switch? Maybe an issue with the code on the switch?

What is the IOS version of the AP? There have been several reported PoE issues with AP codes.

Had this same problem, was racking my brains out. I set the power inline to static and the AP still was only pulling 15.4. I checked SHOW CDP on the switch and sure enough, CDP versions 2 was disabled. Once CDP version 2 was enabled, both AP's came up to full power and showed active.

Thank you!
