Termination must be present at two and ONLY two positions on the SCSI bus-at the beginning of the SCSI bus and at the end of the SCSI bus. Termination is normally enabled by default on the HBA and most internal SCSI cables have a terminator attached. This will usually be a small, rectangular block of plastic attached to the cable end and marked 'SCSI Terminator'. Therefore, assuming the HBA is the first device on the bus, you should check that the second terminator is placed after the last device, as shown in Figure 9 on page 25, item 1.

Where should the SCSI terminator be?
Termination must be present at two and ONLY two positions on the SCSI bus—at the beginning of the
SCSI bus and at the end of the SCSI bus. Termination is normally enabled by default on the HBA and
most internal SCSI cables have a terminator attached. This will usually be a small, rectangular block
of plastic attached to the cable end and marked ‘SCSI Terminator’.
Therefore, assuming the HBA is the
fi
rst device on the bus, you should check that the second terminator is
placed after the last device, as shown in
Figure 9
on page 25, item 1.
