User Service Guide, Fifth Edition - HP Integrity rx8640 SEU

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 the DDS-4 or DVD drive component,
as shown in Figure 5-2, above.
4. Slide the drive in the chassis. Fold the cables out of the way.
5. The drive easily slides into the chassis; however, a slow firm pressure is needed for proper
seating.
6. The front locking tab will latch to secure the disk drive in the chassis.
Removing and Replacing a Disk Drive
The disk drives are located in the front of the chassis. Unless mirroring is used, the nPartition
must be shut down to remove or replace the drive that serves as the boot disk. Refer to “Shutting
Down nPartitions and Powering Off Hardware Components” for more information. The remainder
of the internal disk drives are hot-pluggable.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to
follow ESD safety precautions could result in damage to the SEU.
