To troubleshoot a Link LED that is off on your SMC Networks Switch: * First, make sure that both the switch and the device connected to it are turned on. * Ensure the cable is securely plugged into both the switch and the device. * If the switch is in a rack, check the connections to the punch-down block and patch panel. * Confirm that you're using the correct type of cable and that it's not longer than the specified limit. * Inspect the adapter on the connected device and the cable connections for any signs of damage. If you find a defective adapter or cable, replace it.
