SCSI Card 2940UW Pro User’s Reference
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
configuring 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 have to be sequential, as long as the
SCSI Card 2940UW Pro and each SCSI device has a unique
number. For example, 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, 15 to 8.
■
The SCSI Card 2940UW Pro is preset to SCSI ID 7 and should
not be changed. This gives it the highest priority on the SCSI
bus.
■
Most internal SCSI hard disks come from the factory
preset 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.
■
If you are booting your computer from a SCSI hard disk con-
nected to the SCSI Card 2940UW Pro, the Boot Target ID
setting in the SCSI
Select utility must correspond to the SCSI ID
of the SCSI device you are booting from. By default, the Boot
Target ID is set to
0 . See Boot Device Options on page 16 to
change the Boot Target ID.
■
In Windows
®
95/98 you can use the Device Manager to view
the SCSI ID (and other details) assigned to each SCSI device
installed.
■
If you installed Adaptec
®
EZ-SCSI
®
software, you can use the
SCSI Explorer utility to view the SCSI ID (and other details)
assigned to each SCSI device installed.
