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.

NOTE:
If the drive is in the Advanced Host Controller Interface (AHCI) mode, the status LED indicator does not power on.
NOTE:
Drive status indicator behavior is managed by Storage Spaces Direct. Not all drive status indicators may be used.

System diagnostics and indicator codes
Condition
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.
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.
Condition
Indicates that the drive is being identified or preparing for removal.
Indicates that the drive is ready for removal.
NOTE:
The drive status indicator remains off until all drives are
initialized after the system is powered on. Drives are not ready
for removal during this time.
