Drive indicator codes

The LEDs on the drive carrier indicates the state of each drive. Each drive carrier in your system has two LEDs: an activity LED (green)
and a status LED (bicolor, green/amber). The activity LED flashes whenever the drive is accessed.
Condition
A valid power source is connected to the PSU, and the PSU is
operational.
Indicates a problem with the PSU.
Power is not connected to the PSU.
When hot-plugging a PSU, the PSU indicator blinks green. This
indicates that there is a PSU mismatch about efficiency, feature
set, health status, or supported voltage.
VORSICHT: 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.
VORSICHT: When correcting a PSU mismatch, replace
only the PSU with the blinking 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 conversely, you must to power off the
system.
VORSICHT: If two PSUs are used, they must be of the
same type and have the same maximum output power.
VORSICHT: Combining AC and DC PSUs is not
supported and triggers a mismatch.
