Power supply unit indicator codes
AC power supply units (PSUs) have an illuminated translucent handle that serves as an indicator.
The DC PSUs have an LED 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.
CAUTION:
Do not disconnect the power cord or unplug the PSU when updating
firmware. If firmware update is interrupted, the PSUs do not function.
When hot-plugging a PSU, the PSU handle blinks green five times at a rate of 4 Hz and turns off.
This indicates a PSU mismatch with respect to efficiency, feature set, health status, or supported
voltage.
CAUTION:
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 turn the system
on.
Condition
The NIC is not connected to the network.
The NIC is connected to a valid network at its maximum port speed
and data is being sent or received.
The NIC is connected to a valid network at less than its maximum
port speed and data is being sent or received.
The NIC is connected to a valid network at its maximum port speed
and data is not being sent or received.
The NIC is connected to a valid network at less than its maximum
port speed and data is not being sent or received.
NIC identify is enabled through the NIC configuration utility.
