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
40 EXB-8500/EXB-8500c 306261
