NVMe SSD LED definitions
The NVMe SSD is a PCIe bus device. A device attached to a PCIe bus cannot be removed without allowing the device and
bus to complete and cease the signal/traic flow.
CAUTION: Do not remove an NVMe SSD from the drive bay while the Do not remove LED is flashing. The Do not
remove LED flashes to indicate that the device is still in use. Removing the NVMe SSD before the device has
completed and ceased
signal/traic flow can cause loss of data.
