| CAUTION: When correcting a power supply unit mismatch, |
|
| replace only the power supply unit with the flashing indicator. |
|
| Swapping the opposite power supply unit 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 with the exception of Titanium power supplies, |
|
| which support only 220 V. 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. |
|
| CAUTION: Combining AC and DC power supplies is not |
|
| supported and triggers a mismatch. |
