Power Supply Indicators
| LED Indicator | Description |
|---|---|
| Green (Solid) | A valid power source is connected to the PSU and the PSU is operational. |
| Amber (Blinking) | Indicates an issue with the PSU. |
| Not Lit | Power is not connected to the PSU. |
| Green (Blinking) | PSU firmware is being updated. WARNING: Do not disconnect power or unplug the PSU while firmware is updating. Interruption of this process could lead to PSUs ceasing to function. |
| Green (Blinking and powers off) | When hot-plugging a PSU, it will blink 5 times at a rate of 4Hz then power off. This indicates a mismatch due to efficiency, features, health status, or supported voltage. WARNING: If two PSUs are installed, both PSUs must have the same type of label. Mixing PSUs is not supported, even if they have the same power rating. WARNING: If two identical PSUs receive different input voltages, this can cause different output wattage and trigger a mismatch. CORRECTION: When correcting a PSU mismatch, remove all power from the system then replace the PSU with the blinking indicator. |
