NIC indicator codes Condition
Link indicator is green, and activity indicator is blinking
green.
Indicates that the NIC is connected to a valid network at its maximum
port speed, and data is being sent or received.
Link indicator is amber, and activity indicator is blinking
green.
Indicates that the NIC is connected to a valid network at less than its
maximum port speed, and data is being sent or received.
Link indicator is green, and activity indicator is off. Indicates that 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. Indicates that the NIC is connected to a valid network at less than its
maximum port speed, and data is mot being sent or received.
Link indicator is blinking green, and activity is off. Indicates that the 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 if power is
present or if a power fault has occurred.

Power indicator codes Condition
Green Indicates that a valid power source is connected to the PSU and the PSU is operational.
Blinking amber Indicates an issue with the PSU.
Not powered on Indicates that the power is not connected to the PSU.
Blinking green Indicates that the firmware of the PSU is being updated.
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
powers off
When hot-plugging a PSU, it blinks green five times at a rate of 4 Hz and powers off. This indicates
a PSU mismatch due 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: If two PSUs are used, they must be of the same type and have the same
maximum output power.
CAUTION: When correcting a PSU mismatch, replace the PSU with the blinking
indicator. Swapping the PSU to make a matched pair can result in an error condition
and an unexpected system shutdown. To change from a high output configuration to a
low output configuration or vice versa, you must power off the system.
