Convention Power indicator
pattern
Condition
A Green
A valid power source is connected to the PSU and that the PSU is operational.
B Flashing green When hot-adding a PSU, the PSU indicator flashes green. This indicates that
there is a PSU mismatch with respect to efficiency, feature set, health status, and
supported voltage. Ensure that both the PSUs are of the same capacity.
C Flashing amber Indicates a problem with the PSU.
CAUTION: When correcting a PSU mismatch, replace only the PSU
with the flashing indicator. Swapping the PSU 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 turn off the system.
CAUTION: AC PSU support both 220 V and 110 V input voltages with
the exception of Titanium PSU, which support only 220 V. When
two identical PSU receive different input voltages, they can output
different wattages, and trigger a mismatch.
CAUTION: If two PSU are used, they must be of the same type and
have the same maximum output power.
CAUTION: Combining AC and DC PSU is not supported and triggers a
mismatch.
D Not lit Power is not connected.
iDRAC Direct LED indicator codes
The iDRAC Direct LED indicator lights up to indicate that the port is connected and is being used as a part of the iDRAC
subsystem.
NOTE: The iDRAC Direct LED indicator does not turn on when the USB port is used in the USB mode.
