Power supply unit indicator codes

AC power supply units (PSUs) have an illuminated translucent handle that serves as an indicator. The indicator shows whether power is
present or if a power fault has occurred.
NOTE: The 2400 W and 2000 W PSUs use a C19 or C20 connector. The 1600 W PSUs use a C13 or C14 connector.

Condition
A valid power source is connected to the PSU and the PSU is operational.
Indicates a problem with the PSU.
Power is not connected to the PSU.
When the firmware of the PSU is being updated, the PSU handle blinks green.
CAUTION: Do not disconnect the power cord or unplug the PSU when updating firmware. If
firmware update is interrupted, the PSUs do not function.
indicates a PSU mismatch with respect to efficiency, feature set, health status, or supported voltage.
CAUTION: The PSUs must have the same type of label; for example, Extended Power
Performance (EPP) label. Mixing PSUs from previous generations of PowerEdge servers is not
supported, even if the PSUs have the same power rating. This results in a PSU mismatch
condition or failure to turn the system on.
CAUTION: When correcting a PSU mismatch, replace only the PSU with the blinking 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 PSUs support both 240 V and 120 V input voltages with the exception of Titanium
PSUs, which support only 240 V. When two identical PSUs receive different input voltages, they
can output different wattages, and trigger a mismatch.
Condition
Rebuild stopped.
