New Cisco 3560 POE power deny

So I have a new Cisco switch (Uptime – 6 weeks) that seems to be denying POE power to a specific port. This just happened in the last few days, all other ports are identical in settings and are operational. The end device is a Shoretel deskphone model 530. I’ve read about deny-power bugs in earlier versions of iOS (12.x), but this switch is currently on version 16.6.6.

So far I’ve tried resetting the port, trying different devices, but still no power. No other changes to the port have been made in terms of PoE settings. I’m going to reboot the switch tonight to see if that helps, but in the meantime was wondering if anyone has come across this yet.

Switch model: WS-C3650-48PS iOS Version: 16.6.6
