Table 6. NIC indicators Status Condition Link and activity indicators are off The NIC is not connected to the network. Link indicator is green and activity indicator is blinking green 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 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 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 and DC PSUs have an LED that serves as an indicator. The indicator shows whether power is present or a power fault has occurred. Figure 4. AC PSU status indicator 1 AC PSU status indicator or handle Table 7. AC PSU status indicator 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. 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 turn the system on. 14 Diagnostic indicators

Table 6. NIC indicators
Status
Condition
Link and activity indicators are
off
The NIC is not connected to the network.
Link indicator is green and activity indicator is blinking green
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
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
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.

Power supply unit indicator codes
AC power supply units (PSUs) have an illuminated translucent handle that serves as an indicator and DC PSUs have an LED that serves as
an indicator. The indicator shows whether power is present or a power fault has occurred.

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.
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 turn the system on.
