Adaptec 39106 사용자 설명서

Each device attached to the Adaptec SCSI Card 39160, as well as the 
Adaptec SCSI Card 39160 itself, must be assigned a unique SCSI ID 
number from 0 to 15 for each of the two SCSI buses. A SCSI ID 
uniquely identifies each SCSI device on the SCSI bus and determines 
priority when two or more devices are trying to use the SCSI bus at 
the same time.

Refer to the device’s documentation to set the SCSI ID. Here are 
some general guidelines for SCSI IDs:

■

For internal SCSI devices, the SCSI ID usually is set by config-
uring a jumper on the device. 

■

For external SCSI devices, the SCSI ID usually is set with a 
switch on the back of the device.

■

SCSI ID numbers do not need to be sequential, as long as the 
Adaptec SCSI Card 39160 and each device has a different num-
ber. For example, on each of the two SCSI buses you can have 
an internal SCSI device with ID 0, and an external SCSI device 
with ID 6.

■

SCSI ID 7 has the highest priority on the SCSI bus. The priority 
of the remaining IDs, in descending order, is 6 to 0, then 15 to 8.

■

On both SCSI buses (channels) the Adaptec SCSI Card 39160 is 
preset to SCSI ID 7 and should not be changed. This gives the 
card the highest priority on the SCSI bus.

■

Most internal SCSI hard disk drives come from the factory pre-
set to SCSI ID 0.

■

If you have 8-bit (or Narrow) SCSI devices, they must use SCSI 
IDs 0, 1, 2, 3, 4, 5, or 6. SCSI ID 0 is recommended for the first 
SCSI hard disk drive.

■

If you are booting your computer from a SCSI hard disk drive 
connected to the Adaptec SCSI Card 39160, the Boot SCSI ID 
setting in the SCSISelect utility must correspond to the SCSI ID 
of the device from which you are booting. By default, the Boot 
SCSI ID is set to 0. We recommend that you do not change this 
setting.

In Windows

®

 95/98, you can use the Device Manager to deter-

mine which SCSI ID is assigned to each installed SCSI device.
