8.10.5 TL893 and TL896 Automated Tape Library Internal Cabling
The default internal cabling configurations for the TL893 and TL896
Automated Tape Libraries (ATLs) is as follows:
• The SCSI input for the TL893 is high-density, 68-pin differential. The
default internal cabling configuration for the TL893 is a three-bus mode
shown in Figure 8–14 as follows:
– The top shelf tape drive (SCSI ID 5) and MUC (SCSI ID 2) are on
SCSI Port C and are terminated on the MUC. 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 8–14 it is shown as
part number 0425031, the SCSI Diff Feed Through. This SCSI bus
is terminated on the MUC with terminator part number 0415498, a
50-pin Micro-D terminator.
– The middle shelf tape drive (SCSI ID 4) is on SCSI Port B and is
terminated on the drive with a 68-pin Micro-D terminator, part
number 0415619.
