Figure 8. AC PSU status indicator 1. AC PSU status indicator/handle Table 7. AC PSU status indicators Convention Power indicator pattern A Green B Flashing green C Flashing green and turns off Condition A valid power source is connected to the PSU and the PSU is operational. When the firmware of the PSU is being updated, the PSU handle flashes green. When hot-adding a PSU, the PSU handle flashes green five times at 4 Hz rate and turns off. This indicates a PSU mismatch with respect to efficiency, feature set, health status, and supported voltage. NOTE: Ensure that both the PSUs are of the same capacity. CAUTION: For AC PSUs, use only PSUs with the Extended Power Performance (EPP) label on the back. NOTE: Mixing PSUs from previous generations of Dell PowerEdge servers can result in a PSU mismatch condition or failure to turn the system on. D Flashing amber Indicates a problem with the PSU. CAUTION: When correcting a PSU mismatch, replace only the PSU with the flashing 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 turn off the system. CAUTION: AC PSUs support both 220 V and 110 V input voltages with the exception of Titanium PSUs, which support only 220 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. E Not lit Power is not connected. Dell PowerEdge R830 overview 19

pattern
Condition
A
Green
A valid power source is connected to the PSU and the PSU is operational.
B
Flashing green
When the firmware of the PSU is being updated, the PSU handle flashes green.
C
Flashing green and
turns off
When hot-adding a PSU, the PSU handle flashes green five times at 4 Hz rate and
turns off. This indicates a PSU mismatch with respect to efficiency, feature set,
health status, and supported voltage.
NOTE:
Ensure that both the PSUs are of the same capacity.
CAUTION:
For AC PSUs, use only PSUs with the Extended Power
Performance (EPP) label on the back.
NOTE:
Mixing PSUs from previous generations of Dell PowerEdge servers can
result in a PSU mismatch condition or failure to turn the system on.
D
Flashing amber
Indicates a problem with the PSU.
CAUTION:
When correcting a PSU mismatch, replace only the PSU with
the flashing 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 turn off the system.
CAUTION:
AC PSUs support both 220 V and 110 V input voltages with
the exception of Titanium PSUs, which support only 220 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.
