Diskette Drive Removal

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

1.Disconnect the DC power/interface cables from the back of the diskette drive.

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

2.Press the retaining-tab release button (see Figure 9) and pull the diskette drive assembly forward to remove it from the chassis.

3.Remove the screw securing the diskette drive to the bracket (see Figure 10).

4.Rotate the left side of the diskette drive up until the drive is clear of the retaining tabs.

When you replace the 3.5-inch diskette drive on the bracket, be sure that the two retaining tabs on the right side of the bracket engage the mounting holes in the side of the 3.5-inch diskette drive/bracket. Then replace the screw that holds the diskette drive to the bracket. To replace the 3.5-inch diskette drive assembly in the chassis, slide the bracket tabs into the guides on the chassis until the bracket snaps into place. Reconnect the DC power/interface cables.
