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.

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.
Condition
Indicates that the drive is being identified or preparing for removal.

for removal during this time.
Indicates that there is an expected drive failure.
