    Initial setup information The general information beginning on this page applies to all of the Barracuda 9 drive models. After reading the general informa- tion topics, refer to the appropriate drive-specific section listed below for additional information about configuring and installing your particular model.
  • Page 19 Barracuda 9 Installation Guide, Rev. A SCSI ID jumpers Each device on the SCSI chain must have a unique SCSI ID. The host system’s SCSI controller usually uses the highest-num- bered ID available; therefore the lower-numbered SCSI IDs are normally used for other SCSI devices such as this Barracuda disc drive.
  • Page 20 Barracuda 9 Installation Guide, Rev. A The top example in Figure 2 shows an internal hard disc at one end of the SCSI bus with the SCSI controller at the other end (both are terminated). The bottom example shows two additional SCSI devices connected externally—this means the SCSI con-...
