|
| 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 |

| 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. |

| Power Performance (EPP) label on the back. Mixing PSUs from |
|
| previous generations of servers can result in a PSU mismatch |
|
