Status
Condition
Link indicator is green, and activity indicator is off.
The NIC is connected to a valid network at its maximum port speed,
and data is not being sent or received.
Link indicator is amber, and activity indicator is off.
The NIC is connected to a valid network at less than its maximum
port speed, and data is not being sent or received.
Link indicator is blinking green, and activity is off.
NIC identify is enabled through the NIC configuration utility.
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.

Power indicator codes
Condition
Green
A valid power source is connected to the PSU and the PSU is operational.
Blinking amber
Indicates a problem with the PSU.
Not illuminated
Power is not connected to the PSU.
Blinking green
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.
Blinking green and turns
off
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 power on the
system.
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 power 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.
CAUTION:
If two PSUs are used, they must be of the same type and have the same
maximum output power.
