Convention Power indicator
pattern
Condition
NOTE: For AC power supplies, use only PSUs with the Extended
Power Performance (EPP) label on the back. Mixing PSUs from
previous generations of servers can result in a PSU mismatch
condition or failure to power on.
D 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.
E Not lit Power is not connected.
