If the library is the last device on the SCSI bus, connect terminators to the SCSI output connectors. If the library connects to another SCSI device, connect the SCSI cable from the output of the library to the next SCSI device. Terminate the SCSI output of the final device on the SCSI bus.
Note: It is possible to connect
Adapters are available that terminate the upper eight bits of the wide SCSI bus and interface
See The SCSI Bus on page 118 for details of SCSI bus configuration.
