When adding a new hard drive to SCSI-based RAID systems, you need to ensure that the proper termination exists at either end of the SCSI line. When do you NOT need to attach a termination resistor on the end of the SCSI cable?
A.
When you are using only external SCSI hard drives.
B.
When you are not using external SCSI hard drives.
C.
All of the above
D.
None of the above
Explanation:
When you are using only external SCSI hard drives, you not need to attach a termination resistor on the end of the SCSI cable. This is because of the system automatically implementing termination. For all other scenarios, you must attach a termination resistor on the end of the SCSI cable.
