NO TE
Each SATADOM has a write protection switch. This switch affects only write operations
delivered by the service system to the SATADOM. A SATADOM includes the cache layer and
NAND flash. In normal cases, the write operation is successful only when the data is written
to the NAND flash. When installing a SATADOM, ensure that the write protection switch is
off.
● When the write protection switch is off, the write operation sent by the service system
to the SATADOM directly writes data to the NAND flash of the SATADOM.
● When the write protection switch is on, the write operation sent by the service system to
the SATADOM directly writes data only to the cache layer of the SATADOM, but cannot
write data to the NAND flash. When the cache layer of the SATADOM is full, the
previous data is overwritten. When the device is powered off or restarted, the data at
the cache layer of the SATADOM is lost.
