Replacing Assemblies

To remove and replace the disk drive

To remove and replace the disk drive

1Using previous procedures, remove the following assemblies:

•Handle

•Rear Feet

•Cover

2Disconnect the disk drive cable from the rear of the disk drive.

3Remove the two screws that attach the disk drive bracket to the power supply.

4 Slide the disk drive toward the rear of the instrument, then lift it up and out. 5 Remove the disk drive bracket.

To remove the disk drive bracket, remove the four screws that attach the disk drive bracket to the disk drive.

6Reverse this procedure to install the disk drive.

Check that the following assemblies are properly installed before installing the disk drive:

•Monitor

•Front Panel

•Switch Actuator

•Main Circuit Board

•Power Supply
