Table 92. AC PSU status indicator codes (continued) Power indicator codes Condition 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. When two identical PSUs receive different input voltages, they may output different wattages, and trigger a mismatch. Table 93. DC PSU status indicator codes Power indicator codes Green Blinking amber Not powered on Blinking green Condition Indicates that a valid power source is connected to the PSU, and the PSU is operational. Indicates an issue with the PSU. Indicates that the power is not connected to the PSU. 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.

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 conversely, you must power off the system. CAUTION: Combining AC and DC PSUs is not supported.

Condition
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. When two identical PSUs receive different
input voltages, they may output different wattages, and
trigger a mismatch.

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
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 conversely, you must power off the
system.
CAUTION:
Combining AC and DC PSUs is not supported.
