Installing SCSI Devices
Select models feature a Wide Ultra160 SCSI 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 Ultra160 SCSI 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 communication 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.
