PoE Medium Power

B A — Mon, 05 Jul 2021 18:00:18 GMT

Hello.

I have this issue. I connected many AIR-AP1852I-E-K9 and AIR-AP1852E-E-K9 (they need 20.9W) to different switches that provide 15.4W so I saw "PoE/Medium Power (15.4 W)" on WLC. To provide what my APs need I used a power injector but even after that the WLC says "PoE/Medium Power (15.4 W)".
I tried three power injectors... Cisco, TP-Link and Maxi-Link. Still no joy.

Any idea what is going on?

Where did you find that they need 20.9W?

As per the AP datasheet, they support both standard 802.3at (25.5 W) or 802.3af (15.4 W). According to your description, you are using 802.3af power injector.

I have those AP connected in switches just fine.

Hi @B A ,

Query:

How much power is being delivered by your power injector?

As far as I know, the power injector does not receive power from the switch.

@Flavio Miranda

Where? In Cisco documentation. They need more than 15.4W to be fully functional.

@luis_cordova

I use 30W power injector.
