Compaq AA-RHGWC-TE manual Configuring a Shared Scsi Bus for Tape Drive Use

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 8–18 shows an example of a TruCluster configuration with a TL891 standalone MiniLibrary connected to two shared SCSI buses.
