Red LEDAmber LEDGreen LED
Indicates that power is off.OffOffOff
Indicates that power is on and the drive is busy
with an internal operation. Wait until the
OffGreen/amber flashing alternately (200ms)
operation completes. The drive state should
change to a solid green LED state.
Indicates that either an ATA command is being
processed or power is on, firmware is
OffOffOn
initialized, and there is no host activity. The
drive is operational in either state.
Indicates that PCIe/NAND host activity is in
process. The drive is busy, but operational.
OffOffFlashing (30ms)
Indicates an error code. Error codes are three
digits long and are displayed by blinking the

first digit, then the second, then the third with
pauses in between and a long pause before
repeating. The drive is not operational.
Firmware fatal error codes:
• 112: Failure during DRAM initialization
• 113: Not enough DRAM to run in the
configured mode
• 313: DRAM UECC error
• 441: Error during chip initialization
• 411: Incorrect drive parameters in the
firmware image
Indicates that the drive is backing up internal
data to NAND. The drive is busy, but
operational.
OffFlashing (30ms)Off
Indicates that the drive is in the safe or
“parked” mode. Internal data has been written
to NAND and the drive is safe to power down.
OffOnOff
