I just purchased a Cisco SG200-26P to power three Ubiquiti UAP-LR-3 UniFi AP that are going in a new small network. I added the three AP’s to port 1, 2, and 3 and they are not powering up off the POE switch. I got into the switch and I don’t see anything that stands out for them to not power up. The AP’s work powered up with POE injectors.
SG200-26P is 802.3af compliant but from what I manage to read Ubiquiti UAP-LR is not 802.3af/at compliant, correct me if I am wrong as I did not really find the datasheet for your specific AP. This would mean that the AP would need the injector or specific switch rather than any. As it uses non standard PoE.
