8.1.2 Cabling the TZ88N-VA

There are no special cabling restrictions specific to the TZ88N-VA; it is
installed in a BA350 StorageWorks enclosure. A DWZZA-VA installed in slot
0 of the BA350 provides the connection to the shared SCSI bus. The tape
drive takes up three slots.

You must remove the DWZZA-VA differential terminators. Ensure that
DWZZA-VA jumper J2 is installed to enable the single-ended termination.
The BA350 jumper and terminator must be installed.

A trilink connector on the DWZZA-VA differential end allows connection to
the shared bus. An H879-AA terminator is installed on the trilink for the
BA350 on the end of the bus to provide shared SCSI bus termination.
