3. Install an HD68 differential terminator (such as an H879-AA) on the
right DLT1 connector (the fourth connector from the left).
To connect the drive robotics and two drives to a single shared SCSI bus,
follow these steps:
1. Connect a 328215-00X, BN21K, or BN21L between the last trilink
connector on the bus to the leftmost connector (as viewed from the rear)
of the MiniLibrary.
2. Install a 0.3-meter SCSI bus jumper between the rightmost robotics
connector (the second connector from the left) and the left DLT1
connector (the third connector from the left).
3. Install a 0.3-meter SCSI bus jumper between the rightmost DLT1
connector (the fourth connector from the left) and the left DLT2
connector (the fifth connector from the left).
4. Install an HD68 differential (H879-AA) terminator on the right DLT2
connector (the rightmost connector).
To connect the drive robotics and one drive to one shared SCSI bus and the
second drive to a second shared SCSI bus, follow these steps:
1. Connect a 328215-00X, BN21K, or BN21L between the last trilink
connector on one shared SCSI bus to the leftmost connector (as viewed
from the rear) of the MiniLibrary.
2. Connect a 328215-00X, BN21K, or BN21L between the last trilink
connector on the second shared SCSI bus to the left DLT2 connector
(the fifth connector from the left).
3. Install a 0.3-meter SCSI bus jumper between the rightmost robotics
connector (the second connector from the left) and the left DLT1
connector (the third connector from the left).
4. Install an HD68 differential (H879-AA) terminator on the right DLT1
connector (the fourth connector from the left) and install another HD68
differential terminator on the right DLT2 connector (the rightmost
connector).
Figure 8–17 shows an example of a TruCluster configuration with a TL891
standalone MiniLibrary connected to two shared SCSI buses.
