If the Power LED on your TP-Link TL-SF1008LP Unmanaged Desktop PoE-PoE+ Switch isn't illuminated, it points to a potential power issue. To troubleshoot this, begin with these steps:
- Power Cord Check: First, ensure the AC power cord is firmly plugged into both the switch and a working power outlet.
- Voltage Verification: Confirm that the power supply's voltage matches the input voltage requirements specified for your switch model. You can usually find these specifications on the switch itself or in its documentation.
- Power Source Assessment: Verify that the power outlet you're using is functioning correctly. Try plugging another device into the same outlet to confirm it's providing power.
If the Power LED remains off after these checks, there might be an issue with the switch or its power supply. In this case, contact TP-Link support for further diagnosis and assistance.
