s Each SCSI controller requires a unique SCSI ID (0-7 or 8-15) for each SCSI device installed. The controller identifies a SCSI device by its SCSI ID number rather than by its location. Moving a SCSI device from one position to another on the SCSI chain does not affect communication between the controller and the device. The reserved and available SCSI ID numbers for SCSI devices are the following: ❏ 0-reserved for the primary hard drive ❏ 7-reserved for the controller ❏ 1 through 6 and 8 through 15 - available for all other SCSI devices s If only one SCSI hard drive is used, it should be installed in the lowest numbered bay (bay 1). s Every SCSI chain or circuit must be terminated (closed) at both ends. Some system boards have both ends of the SCSI cable connected to, and terminated by, the system board. Termination can be accomplished through one of the following methods: ❏ Using a cable with a built-in terminator. ❏ Using a cable with a terminating resistor plug in the last connector. ❏ Connecting a SCSI device with its termination enabled into the last connector. ❏ Connecting an external SCSI device with its termination enabled to the external SCSI connector on the rear panel of the computer.

■
Each SCSI controller requires a unique SCSI ID (0-7 or 8-15) for
each SCSI device installed. The controller identifies a SCSI device
by its SCSI ID number rather than by its location. Moving a SCSI
device from one position to another on the SCSI chain does not
affect communication between the controller and the device. The
reserved and available SCSI ID numbers for SCSI devices are the
following:
0–reserved for the primary hard drive
7–reserved for the controller
1 through 6 and 8 through 15 – available for all other SCSI
devices
■
If only one SCSI hard drive is used, it should be installed in the
lowest numbered bay (bay 1).
■
Every SCSI chain or circuit must be terminated (closed) at both
ends. Some system boards have both ends of the SCSI cable
connected to, and terminated by, the system board. Termination
can be accomplished through one of the following methods:
Using a cable with a built-in terminator.
Using a cable with a terminating resistor plug in the last
connector.
Connecting a SCSI device with its termination enabled into
the last connector.
Connecting an external SCSI device with its termination
enabled to the external SCSI connector on the rear panel of
the computer.
