NIC indicator codes Condition
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.
