IDE Configuration Information
The IDE subsystem provides one primary channel. See Figure A-3 for the location of the system
board primary IDE connector. The primary channel can support up to two IDE drives (such as CD
drives, data-only DVD drives, and half-height tape drives).
Each IDE drive should be configured for the Cable Select setting, which assigns master and slave
status to a drive according to its position on the interface cable. In this configuration, the drive
attached to the last connector on the interface cable is the master or boot drive (drive 0) and the
drive attached to the middle connector on the interface cable is the slave drive (drive 1). See the
drive's documentation for instructions on configuring the Cable Select setting.
SATA Configuration Information
The SATA subsystem provides two SATA channels. See Figure A-3 for the locations of the system
board SATA connectors. Each SATA channel can support one non–hot-plug SATA hard drive.
Each 7-pin SATA hard drive cable connects directly between the system board SATA connector and
the SATA hard drive. The SATA hard drive that is connected to the system board SATA 0 connector
is designated as the primary SATA hard drive, and the SATA hard drive that is connected to the
SATA 1 connector is the secondary hard drive.
SCSI Configuration Information
Although SCSI drives are installed in essentially the same way as other drives, their configuration
requirements are different. To install and configure a SCSI drive, follow the guidelines in the
following subsections.
SCSI Interface Cables
SCSI interface connectors are keyed for correct insertion. Keying ensures that the pin-1 wire in the
cable connects to pin 1 in the connectors on both ends. When you disconnect an interface cable,
take care to grasp the cable connector, rather than the cable itself, to avoid stress on the cable.
SCSI ID Numbers
Each drive attached to a SCSI controller must have a unique SCSI ID number from 0 to 15.
• The SCSI hard drive from which the system boots is configured as SCSI ID 0.
• A SCSI tape drive is typically configured as SCSI ID 6.
• If you install optional SCSI half-height drives or change your SCSI configuration, see the
documentation for each SCSI drive for information on setting the appropriate SCSI ID
number.
NOTE:
There is no requirement that SCSI ID numbers be assigned sequentially or that drives be
attached to the cable in order by ID number.
