4.1.1.
SCSI Cabling
•
Only the SCSI-FC Router attaches to a differential interface and a differential
terminator.
•
SCSI cable length for the SCSI-FC Router should not exceed 25 meters (82 feet).
•
SCSI-FC Router supports attachment to an external 68 pin SCSI-II shielded cable.
4.1.2. SCSI
Termination
SCSI termination must exist at both ends of the SCSI bus (see Figure 4-1). To terminate the
SCSI-FC Router’s SCSI bus add the External SCSI-FC Router SCSI terminator. To terminate
the attached SCSI device(s), refer to the SCSI device’s (tape or disk drive) operating manual
for information concerning proper termination.

Copper and Fiber Optic Cabling
Termination is automatically provided with the Fibre Channel architecture, therefore
termination is not needed.
