Compaq AA-RHGWC-TE - Manual (Page 241)

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 BN21K or BN21L between the last trilink connector on one
shared SCSI bus to the leftmost connector (as viewed from the rear) of
the TL892.
2. Connect a 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 H879-AA terminator on the right DLT1 connector (the fourth
connector from the left) and install another H879-AA terminator on the
right DLT2 connector (the rightmost connector).
Figure 8–10 shows an example of a TruCluster Server cluster with a TL892
connected to two shared SCSI buses.
