Attention: If you move the disk drive from a colder or warmer environment than the room where it will be used, allow the disk drive to gradually reach the temperature of the room. By allowing the disk drive time to acclimate, data loss or permanent damage to the disk drive can be avoided. The proper time is at least one hour for each 10°C (18°F) of difference between the storage environment and the operating environment.

1.Slide the riser card into the guides in the disk drive frame.

2.Using a side-to-side motion, carefully plug the disk drive into the riser card.

3.Install the four screws into the disk drive.

4.Ensure that the power supply connectors P3 and P4 are connected into J3 and J4 on the planar.

Note: If the frame contains a combination of one SCSI and one bus-attached drives, either P3 or P4 are attached to the SCSI drive instead of J3 or J4 on the planar. Also, the cable from the SCSI drive must be attached to the SCSI I/O controller.

5.If a SCSI drive is present, route the SCSI signal cable under the rear drive.

6.Install the frame assembly and push the latch to its closed position.
