Remove the DDU and the carrier. Pull the DDU and the carrier straight out
of the media card.
WARNING
Ejector arm damage
Ensure that the ejector arm is flat and in the up position on
the faceplate. Insert the DDU in the media card faceplate.
Complete this procedure to avoid damage to the ejector arm.
Insert the new DDU through the aperture in the media card faceplate. Ensure
that the connector at the end of the unit will plug into the receptacle on the
card.
Reconnect the DDU electrically with the media card. Turn the spring-loaded
lock mechanism to the right to make the connection between the new DDU
and the media card.
After the drive connects, the green LED will be ON and the red LED will
remain OFF.
