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.

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.
VORSICHT: 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.
VORSICHT: If two PSUs are installed, both 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 power on the system.
VORSICHT: 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 power off the system.
VORSICHT: 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.
VORSICHT: If two PSUs are used, they must be of the same type and have the same
maximum output power.
Condition
NIC identify is enabled through the NIC configuration utility.
