Exabyte EXB-8500c 8mm SCSI Cable Connector, Attaching the Tape Drive to a Frame, Configurations

Note: To minimize discontinuities and signal reflections, ensure that cables used on the same bus have the same impedances.

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 Cable 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-8500 and EXB-8500c Product Specification.

Attaching the Tape Drive to a Frame

The main housing of the tape drive includes two sets of mounting holes (one set on the sides and one set on the bottom, as shown in Figures 14 and 15) to allow for a number of mounting positions. These mounting holes accommodate #6-32 screws. Refer to the EXB-8500 and
