AC Power Supply Status Indicators
Each AC power supply has an illuminated translucent handle that indicates whether power is present or whether a power fault has occurred.
| OK LED | Status |
| Green | A valid power source is connected to the power supply and the power supply is operational. |
| Flashing green | When updating the firmware of the power supply unit is being updated, the power supply handle flashes green. |
| Flashing green and turns off | When hot-adding a power supply, the power supply handle flashes green five times at 4 Hz rate and turns off. This indicates that there is a power supply mismatch with respect to efficiency, feature set, health status, and supported voltage. Replace the power supply with a power supply that matches the capacity of the other power supply. |
| Flashing amber | Indicates a problem with the power supply. |
