Power Indicator Codes
Each AC power supply has an illuminated translucent handle that serves as an indicator to show whether power is present or whether a power fault has occurred.
Figure 5. AC Power Supply Status Indicator
1. AC power supply status indicator/handle
Power Indicator | Condition |
Pattern |
|
Not lit | Power is not connected. |
Green | The handle/LED indicator lights green indicating that a valid power source is connected to the |
| power supply and that the power supply is operational. |
Flashing amber | Indicates a problem with the power supply. |
| CAUTION: When correcting a power supply mismatch, replace only the power supply with |
| the flashing indicator. Swapping the opposite power supply to make a matched pair can |
| result in an error condition and unexpected system shutdown. To change from a High |
| Output configuration to a Low Output configuration or vice versa, you must power down |
| the system. |
| CAUTION: AC power supplies support both 220 V and 110 V input voltages. When two |
| identical power supplies receive different input voltages, they can output different |
| wattages, and trigger a mismatch. |
| CAUTION: If two power supplies are used, they must be of the same type and have the |
| same maximum output power. |
Flashing green | When |
| other power supply (in terms of efficiency, feature set, health status, and supported voltage). |
| Replace the power supply that has the flashing indicator with a power supply that matches the |
| capacity of the other installed power supply. |
