Unable to power some APs with PoE+

[Ludofloria]

Hey there

I currently use second hand Cisco 2960S switches (full ref: C2960S-24PS-L).

According to the Data Sheet, they are 802.3at-compliant, meaning I can use them to power up 30W devices.

I purchased multiple Netgear APs, which are PoE+ enabled and should be perfectly powered-up by the switches.

However, when I plug them into my switches, I got a « Insufficient Power » error. The AP seems to believe it's connected to a 802.3af port.

How can I force a port to be 802.3at and make my APs work as intended?

I've connected those AP to a Sophos XGS126 firewall with two PoE+ port, and the APs boots up with no errors, meaning the problem comes from the switches giving them the Power.

Thanks in advance for your help

Hello !

I tried your command, but with no more luck...

I'm thinking more and more than since the switch doesn't handle 4 wire power, my APs won't work with it

Could it be your cable plant? Do you get the same error if you hook the AP direct to the switch without going through your jack field/cable plant?

The cables are brand new, and the APs are directly connected to the switch
