What to do if the Link/ACT LED is off on my TP-Link TL-SL5428?

If the Link/ACT LED is off on your TP-Link Switch, first ensure that both the switch and the connected device are powered on. Next, verify that the cable is securely plugged into both the switch and the corresponding device. If the switch is in a rack, inspect the connections to the punch-down block and patch panel. Confirm that you're using the correct cable type and that its length doesn't exceed the specified limits. Finally, check the adapter and cable connections on the attached device for any defects and replace them if needed.
