Instructions
Prepare the new disk drive assembly for installation in the analyzer. The
Installation Note included in the service kit provides details for this procedure.
1. Disconnect the power cord and remove the top, bottom, and left side-covers
(refer to “Covers” in this chapter).
2. Turn the analyzer over, so that the bottom faces up.
3. Disconnect the ribbon cable (item 1) that connects to the disk drive from its
connector on the CPU board.
4. Remove the four screws (item 2) that secure the disk-drive bracket to the
side of the analyzer, and remove the complete disk drive assembly.
Note
Save the screws removed in this step for use later when
installing the new disk drive bracket.
5. Disconnect the ribbon cable from its connection on the disk drive.
