Removal and Replacement Procedures

Disk and Tape Drive

To remove and replace disk and/or tape drives, follow these procedures.

Removal

1.Turn the power OFF to all equipment and disconnect the power cable from the AC power source.

2.Slide the MVME956AC chassis out from its rack mounting remove the top panel and the side panel nearest the drives.

3.Remove the front bezel.

4.Loosen the screws that engage the keyhole slots in the right side access cover. Lift the cover up and off the screws.

5.Remove the screws on either side of the drive and partially pull the drive out of the chassis. Disconnect the data and power cables. Remove the drive from the chassis.

6.Remove the screws connecting the drive mount bracket to the drive.

Note: If this is a permanent removal, ensure that the remaining drive identifications are correct and the terminating resistor is properly installed.

7.If the drive is to be immediately replaced, go on to the replacement procedure at this point.

8.Position the side access cover on the screws to engage the keyhole slots properly. The washers must be on the outside of the cover.

9.When the screws have properly engaged the keyhole slots, slide the cover down and tighten the screws.

10.Replace the front bezel.

11.Slide the MVME956AC chassis back into its rack mounting or replace the side panel and the top panel to your lab benchtop unit.
