PoE Status on Airnet

[erichusidley]

Our wireless environment has a mix of Airnet 3500, 3600, 3700, and 3800.

Some of Airnet models connect to the same switch but show different PoE Status:

PoE/Full Power

PoE/Medium Power (15.4 W)

Power injector / Full Power - I verify that Airnet connects to the PoE switch directly.

DC / Full Power

Do you kindly provide me a link or explain what each mean?

Thanks,

If they are connect to the same switch, please post full output of "sh power inline | i AIR" command output from switch.

For Cisco 3800 series APs, I know couple of bugs which shows incorrect POE Status for APs (CSCvd75447 & CSCva91922). Can you share WLC software version.

So if you have all the models listed below connected to a switch that can only provide 802.af (15.4W) it will give different outputs per the generation AP you got.

The Cisco 3500 and 3600 (without the external modules) will operate at all radio features supported 4x4:3 on 2.4/5 GHz by the AP at 15.4W and therefore you should see Full PoE Power

The Cisco 3700 will run at 3x3:3 on 2.4/5 GHz when getting 15.4W which should show you Medium Power, if it receives its required PoE budget of 16.8W (excluding external modules) it's radios can operate at 4x4:3 on 2.4/5 GHz.

For the Cisco 3800 the 15.4W power will only be enough for the AP to boot up and join the WLC, it won't have enough power to power up both 2.4 and 5GHz radios. You will need a 802.3at PoE+, Cisco Universal Power over Ethernet (Cisco UPOE) switch or 802.3at power injector (AIR-PWRINJ6=) or 50W power supply (AIR-PWR-50=)
