8.1.2 Cabling the TZ88N-VA
There are no special cabling restrictions specific to the TZ88N-VA; it is
installed in a BA350 StorageWorksenclosure. ADWZZA-VA installed in slot
0 of the BA350 provides the connection tothe shared SCSI bus. The tape
drive takes up three slots, so two SCSI IDsare unavailable for disks in this
StorageWorksenclosure. Another BA350 may be daisy chained to allow the
use of the SCSI IDs unavailable in the first StorageWorks enclosure due to
the TZ88 tape drive.
Youmust remove the DWZZA-VA differential terminators. Ensure that
DWZZA-VAjumper J2 is installed to enable thesingle-ended termination.
The BA350 jumper and terminator must be installed.
A trilink connector on the DWZZA-VAdifferential end allows connection to
the shared bus. An H879-AA terminator is installed on thetrilink for the
BA350 on the end of the bus to provide shared SCSI bus termination.
Figure 8–2 shows a TruCluster Server cluster with two shared SCSI buses.
The top shared bushas a BA350 with disks at SCSI IDs 1, 2, 4, and 5. The
other BA350 contains a TZ88N-VAat SCSIID 3.
