#### Power Supply and AC Power Connector LEDs

Each power supply is provided with a set of three LEDs, which are located at the front of the server.

No. | LED | Icon | Description
--- | --- | --- | ---
1 | Fault (amber) |  | Lights when the power supply is faulty. Note - The front and rear panel Service Required LEDs are also lit if the server detects a power supply fault.
2 | OK (green) |  | Lights when the power supply DC voltage from the PSU to the server is within tolerance.
3 | AC Present (green) | ~AC | Lights when AC voltage is applied to the power supply.

Note - If a power supply fails and you do not have a replacement available, leave the failed power supply installed to ensure proper airflow in the server.

Each AC power connector has a single LED.
