Table 6. DC Power indicator
Convention Power indicator
pattern
Condition
A Green The handle/LED 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 hot-adding a power supply unit, power supply unit LED
flashes green. 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.
C Flashing amber Indicates a problem with the power supply unit.
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.
D Not lit Power is not connected.
