Compaq AA-RHGWB-TE manual Cabling a Shared Scsi Bus with a TZ887

The single-ended SCSI bus may be daisy chained from one single-ended tape drive to another with BC19J cables, as long as the SCSI bus maximum length is not exceeded and there are sufficient SCSI IDs available. Ensure that the tape drive on the end of the bus is terminated with an H8574-A or H8890-AA terminator.

You can add additional shared SCSI buses with TZ887 tape drives by adding additional DWZZB-AA/TZ887 combinations.

______________________ Note _______________________

Ensure that there is no conflict with tape drive, host bus adapter, and disk SCSI IDs.
