Table 37. NIC indicator codes (continued) NIC indicator codes Link indicator is blinking green, and activity is off. Condition 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. Figure 9. AC PSU status indicator 1. AC PSU status indicator/handle Table 38. AC PSU status indicator codes 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. 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. Table 39.

Table 37. NIC indicator codes (continued)
NIC indicator codes
Condition
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.

AC PSU status indicator/handle
Table 38. AC PSU status indicator codes
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.
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.
