Diskette Drive Removal

CAUTION: Before you remove the computer cover, see "Precautionary Measures"

To remove the 3.5-inch diskette drive assembly, perform the following steps:

1.Rotate the system power supply up and out of the system (see Figure 20).

2.Disconnect the DC power cable from the back of the diskette drive.

3.Disconnect the interface ribbon cable from the back of the diskette drive.

The other end of this ribbon cable is connected to the DISKETTE connector on the system board (see Figure 22 for the location of the DISKETTE connector).

Note the routing of the DC power and interface ribbon cables through the chassis as you disconnect them. It is important to route the cables properly when you replace them to prevent them from being pinched or crimped.

4.Press down on the retaining-tab release button (see Figure 12) and pull the drive assembly forward to remove it from the chassis.
