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 and host bus adapter SCSI IDs.
