Installing SCSI
Devices
Select models feature a Wide Ultra2 SCSI or Wide UltraSCSI
host adapter that supports up to fifteen wide internal and
external SCSI devices. Select models come with an internal
SCSI hard drive preinstalled. Additional high-performance
SCSI devices can be added to these select models.
Guidelines for Installing Optional SCSI Devices
When installing additional SCSI devices, you must adhere to the
following guidelines:
■
The Wide Ultra2 SCSI or Wide UltraSCSI host adapter
supports up to 15 wide SCSI devices.
■
Every SCSI device must have a unique identification (ID)
number (0 - 15). The SCSI host adapter identifies signals to
and from a SCSI device by its SCSI ID number rather than
its location. Moving a SCSI device from one position to
another on the SCSI chain does not affect the communi-
cation between the controller and the SCSI device. The
reserved and available SCSI ID numbers for SCSI devices
are as follows:
❏ 0 is reserved for the hard drive.
❏ 1 through 4 are available.
❏ 5 is reserved for a CD-ROM drive.
❏ 6 is available.
❏ 7 is reserved for the SCSI host adapter.
❏ 8 - 15 are available.
