Maintenance and troubleshooting
Fixed power supply failure
The switch uses fixed power supplies and supports only AC power input. You can identify the power
supply operating status by observing the system status LED on the switch.
Symptom
The system status LED on the switch is off.
Solution
To resolve the issue:
1.
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.
2.
Verify that the AC power source is operating correctly.
3.
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 protection state.
4.
If the issue persists, contact H3C Support.
