SCSI Hard Disk Drives
The system supports a variety of SCSI devices. As shipped from the
supplier, the system might contain no hard disk drives. Contact your sales
representative or dealer for a list of approved SCSI devices. If you install
10,000 rpm SCSI hard drives, you must install heat sinks on the drives and
additional fans in the chassis. See the sections below for specific
instructions.
Installing Heatsinks on High-Power Drives
If you plan to use SCSI drives whose power exceeds 15 watts, you must
install heatsinks on those drives.
1. Position each heatsink (Figure 19) so that the three screw holes in the
heatsink align with the corresponding holes in the hard drive. The
holes are placed so that you can position the heatsink in only one way:
with the fins extending along the side and the top of the hard drive.
