CBS220-24P-4G PoE Issue

Hello Everyone,

i'm running into a very peculiar issue with a brand new CBS220 switch. When i connected the 2 PoE Accesspoints that we want to run to it, they powered up and worked with no issues. I then proceeded to configure the VLANs and ports to what is needed for our setup. Meaning i configured the Switchports to: Mode Trunk, VLAN allowed 1,2, Native VLAN 1.

This resulted in the switch no longer providing power to the Accesspoints.

I did not change any PoE settings while doing the configuration, i only changed the afforementioned VLAN settings. Strangely enough it also doesnt do anything to undo the configurations on those switchpowers. The switch just refuses to power the devices.

The Ports in Question are Gi23 & Gi 24. The Power line status looks as follows:

I did try various changes in PoE Configuration and the like, to no avail. I also tried a factory reset which resulted in PoE working again, until i did the Trunk configuration on the ports.

I installed the most current firmware for the device, which also didn't help.

Wishing you all a great day,and thanks in advance for any advice!
