Cable Length Requirements for Differential

Configurations

For differential SCSI configurations, ensure that the sum of all the SCSI cable lengths does not exceed 25.0 meters (82.02 feet). A stub length of no more than 0.2 meters

(8 inches) is allowed off the mainline interconnection within any connected equipment. The stub length within the tape drive is less than 50 mm (1.97 inches).

Cable Length Requirements for Single-Ended

Configurations

For single-ended SCSI configurations, ensure that the sum of all the SCSI cable lengths does not exceed 6.0 meters (19.68 feet). A stub length of no more than 0.1 meters (4 inches) is allowed off the mainline interconnection within any connected equipment. The stub length within the tape drive is less than 50 mm (1.97 inches).

SCSI Connector

To connect the tape drive to the SCSI bus, use a 50-pin female ribbon cable connector (AMP™ No. 1-746285-0 or equivalent). The tape drive’s SCSI connector is located at the rear of the tape drive. The connector is a 50-pin male ribbon cable connector, consisting of two rows of 25 pins with adjacent pins 2.54 mm (0.1 inch) apart. For information about the specific SCSI connector pin assignments for differential and single-ended tape drives, refer to the EXB-8205 and EXB-8505 Product Specification.
