Power Indicator
Pattern
Condition
CAUTION: When correcting a power supply mismatch, replace only the power supply with the ashing
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 conguration to a Low Output
conguration 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 dierent
input voltages, they can output dierent 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.
Flashing green When hot-adding a power supply, this indicates that the power supply is mismatched with the other power supply
(in terms of eciency, feature set, health status, and supported voltage). Replace the power supply that has the
ashing indicator with a power supply that matches the capacity of the other installed power supply.
