Drive indicator codes
The LEDs on the drive carrier indicates the state of each drive. Each drive carrier has two LEDs: an activity LED (green) and a status LED
(bicolor, green/amber). The activity LED blinks whenever the drive is accessed.

System diagnostics and indicator codes
Condition
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.
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.
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.
