cable). Ensure that the trilink or Y cable at both ends of the differential
segment of the shared SCSI bus is terminated with an HD68 differential
terminator such as an H879-AA.
The single-ended SCSI bus may be daisy chained from one single-ended
tape drive to another with cable part number 146745-003 or 146776-003
(0.9-meter cables) as long as the SCSI bus maximum length of 3 meters (fast
SCSI) is not exceeded. Ensure that the tape drive on the end of the bus is
terminated with terminator part number 341102-001.
You can add additional shared SCSI buses with Compaq 20/40 GB DLT
Tape Drives by adding additional DWZZB-AA/Compaq 20/40 GB DLT Tape
Drive combinations.
______________________ Notes ______________________
Ensure that there is no conflict with tape drive and host bus
adapter SCSI IDs.
To achieve system performance capabilities, we recommend
placing no more than two Compaq 20/40 GB DLT Tape Drives on
a SCSI bus, and also recommend that no shared storage be placed
on the same SCSI bus with the tape drive.
