How to fix a power LED that is off on an Edge-Core ES3528M-PoE?
If the power LED on your Edge-Core Network Router is off, the power supply might be disconnected. Check the connections between the switch, the power cord, and the wall outlet to ensure everything is properly connected. If the issue persists, contact your dealer for assistance.
What to do if the Link LED is off on an Edge-Core ES3528M-PoE?
If the Link LED is off on your Edge-Core Network Router, make sure that both the switch and the connected device are powered on. Also, ensure the cable is securely plugged into both the switch and the device. If the switch is in a rack, check connections to the punch-down block and patch panel. Verify the correct cable type is used, and that its length doesn't exceed specified limits. Check the adapter on the attached device and cable connections for any defects. If necessary, replace any defective adapters or cables.
Why is my Edge-Core ES3528M-PoE overheating?
If you're experiencing power and cooling problems with your Edge-Core Network Router, check for loose power connections, power losses, or surges at the power outlet. Make sure the fans on the unit are unobstructed and running correctly before shutting down. If the problem persists, the internal power supply may be defective.
How to troubleshoot installation issues with an Edge-Core ES3528M-PoE?
During the installation of your Edge-Core Network Router, verify that all system components have been properly installed. If any components seem to be malfunctioning, test them in an alternate environment where you are certain that all other components are functioning correctly.
