• The SCSI input for the TL896 is also high-density, 68-pin differential.
The default internal cabling configuration for the TL896 is a six-bus
configuration shown in Figure 8–16 as follows:
– The upper bay top shelf tape drive (tape drive 5, SCSI ID 5) and
MUC (SCSI ID 2) are on SCSI Port D. To allow the use of the same
MUC and terminator used with the TL822 and TL826, a 68-pin to
50-pin adapter is used on the MUC to connect the SCSI cable from
the tape drive to the MUC. In Figure 8–16 it is shown as part number
0425031, SCSI Diff Feed Through. This SCSI bus is terminated on
the MUC with terminator part number 0415498, a 50-pin Micro-D
terminator.
– The upper bay middle shelf tape drive (tape drive 4, SCSI ID 4) is on
SCSI Port E and is terminated on the tape drive.
– The upper bay bottom shelf tape drive (tape drive 3, SCSI ID 3) is on
SCSI Port F and is terminated on the tape drive.
– The lower bay top shelf tape drive (tape drive 2, SCSI ID 5) is on
SCSI Port A and is terminated on the tape drive.
– The lower bay middle shelf tape drive (tape drive 1, SCSI ID 4) is on
SCSI Port B and is terminated on the tape drive.
