I recently set up a TP-Link 28-Port Gigabit Easy Smart Switch with 24-Port PoE+ (TL-SG1428PE) for my small office network. Everything seemed fine at first, but I have noticed that a few PoE devices specifically some IP cameras and an access point - either fail to power on or randomly disconnect.

All cables are Cat6 and under 50 meters, and the total PoE load should not be exeeding the switch's rated power budget. I have tried rebooting and even updated the firmware, but the issue still comes up occasionally.

Has anyone faced similar problem with this model?? Could it be a power allocation issue or something related to port configuration?? Any troubleshooting tips would
