Figure 14. AC power supply unit status indicator
1.AC power supply unit status indicator/handle
Convention | Power indicator | Condition |
| pattern |
|
|
|
|
A | Green | The handle indicator lights green indicating that a valid power |
|
| source is connected to the power supply unit and that the power |
|
| supply unit is operational. |
B | Flashing green | When updating the firmware of the power supply unit, the power |
|
| supply unit handle flashes green. |
C | Flashing green | When |
| and turns off | handle flashes green five times at 4 Hz rate and turns off. This |
|
| indicates that the power supply unit is mismatched with the other |
|
| power supply unit (in terms of efficiency, feature set, health status, |
|
| and supported voltage). Replace the power supply unit that has the |
|
| flashing indicator with a power supply unit that matches the capacity |
|
| of the other installed power supply unit. |
|
| NOTE: For AC power supplies, use only PSUs with the Extended |
|
| Power Performance (EPP) label on the back. Mixing PSUs from |
|
| previous generations of servers can result in a PSU mismatch |
|
| condition or failure to power on. |
D | Flashing amber | Indicates a problem with the power supply unit. |
