The following table describes the three power supply LEDs

Table 31 Power Supply Status LEDs

Legend | LED | Icon | Color |
--- | --- | --- | --- | ---
1 | OK |  | Green | This LED lights when the power supply DC voltage from the PSU to the server is within tolerance.
2 | Fault |  | Amber | This LED is lit when the power supply is faulty. Note - The front and rear panel Service Required LEDs are also lit if the system detects a power supply fault.
3 | AC Present | ~AC | Green | This LED turns on when AC voltage is applied to the power supply. Note - For DC models, this is the DC input OK LED. It turns on when the input DC power is present.

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.
