NO TE
Each SATADOM has a write protection switch. This switch aects only write operations
delivered by the service system to the SATADOM. A SATADOM includes the cache layer and
NAND
ash. In normal cases, the write operation is successful only when the data is written
to the NAND ash. When installing a SATADOM, ensure that the write protection switch is
o.
● When the write protection switch is o, the write operation sent by the service system
to the SATADOM directly writes data to the NAND
ash 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 ash. When the cache layer of the SATADOM is full, the
previous data is overwritten. When the device is powered o or restarted, the data at
the cache layer of the SATADOM is lost.
Step 5 Insert the SATADOM vertically into the connector on the mainboard until it snaps
into place. See Figure 7-126.
