This switch's specific model is SG2210P V3 right?
Are all the clients connected to the switch actually working properly?
And this model is able to set LED on or off, if the ethernet port LEDs are set to off, this problem may occur, you can go to the controller interface to check, as shown in the following figure.

It does seem a bit strange if you are using the original power supply to power this switch.
If you think it's affecting the usage, suggest contacting support directly would handle it better.

Dear @nicklargent,

Same issue here. Everything was working fine until I moved some stuff around. When I connected it back up I only get the power LED. All connected devices are working fine and the OC200 has power but all of the Link/PoE LEDS and System LED are off. The LED setting in Config is 'On'.

Thank you for your kind feedback. Please allow me to check more detailed information here.

Do you also have the same issue with the TL-SG2210P switch? May I know the hardware and firmware version? 

What Omada devices do you have? Does the issue only exist with the specific switch?

What did you do before the issue started to occur? Is there anything special?

Dear @Penn50, do you still keep the switch in your network and does the issue still exist? 

May I know the hardware and firmware version of the switch?
