AC input failure
Symptom
The system status LED is off.
Solution
To resolve the problem:
Verify that the AC power cord is securely connected to the switch, and the AC-input power receptacle on the switch and the connected AC power outlet are in good condition.
Verify that the AC power source is operating correctly.
Verify that the operating temperature of the switch is in the acceptable range, and the power supply has good ventilation. Over-temperature can cause the power supply to stop working and enter the protection state.
