NOTE: The figure shown above displays two DVD components. Either or both items may be
replaced by a DDS-4 component.
1. To remove the DDS-4 or DVD drive, push the front locking tab toward the DDS-4 or DVD
drive, then pull the tab out to slide the DDS-4 or DVD drive out of the chassis.
NOTE: DDS-4 or DVD drive components include removable rails attached to both sides.
If the component is to be replaced, ensure that the replacement component includes the
plastic rails. If the rails are not included, extract the pin that holds each rail, remove the rail,
and install both rails on the replacement component. There are two sets of holes on each
side of the DDS-4 or DVD drive component. Ensure that the rails are mounted so that the
pins fit into the bottom set of holes. One of the rails has a locking tab attached. Ensure that
the rail with the locking tab is mounted on the left side of theDDS-4 or DVD drive component,
as shown in Figure 5-2, above.
2. Disconnect the power and SCSI cables from the rear of the DDS-4 or DVD drive.
3. Pull the DDS-4 or DVD drive from the chassis and set aside.
NOTE: If the system has only one DDS-4 or DVD drive installed, a tray will be located beneath
the DDS-4 or DVD drive as shown in the preceding figure. Follow the same removal procedure
to extract the tray, pushing the bottom front locking tab toward the tray then pulling out on the
tab to remove it from the chassis.
