– The desktop model is connected to the DWZZA–VA using a 68-conductor,
differential (SCSI–P) cable, such as a BN21K or BN21L.
With a SCSI bus signal converter you can extend the maximum length of the
SCSI bus. This distance is measured from the terminator on the SCSI host to the
terminator on the SBB shelf. This length includes the following:
• The distance from the host terminator to the host SCSI cable connector
• The length of all cables
• The distance from the SBB shelf input connector or the DWZZA–VA connector
to the shelf terminator
