Maintenance and troubleshooting
Power supply failure
Symptom
The power supply has failed.
NOTE: You can use the LEDs on the power supply to identify a power supply failure. For more information about the LEDs on a
power supply, see HPE A58x0AF 650W AC (JC680A) & 650W DC (JC681A) Power Supplies User Guide or HPE FlexFabric
Switch 650W 48V Hot Plug NEBS Compliant DC Power Supply (JH336A) User Guide.
If the LEDs on the power supply are not steady green (active) or blinking green (standby), the power supply is faulty.
To replace a hot swappable power supply, see
Installing/removing a power supply on page 27.
Action
1. Verify that the power cord is connected securely.
2. Verify that the power source meets the requirement.
3. Verify that the temperature of the switch is in the normal range and the power supply has good ventilation.
4. If the problem persists, contact Hewlett Packard Enterprise Support.
