B Initial setup information The general information beginning on this page applies to all of the Barracuda 9 drive models. After reading the general information topics, refer to the appropriate drive-specific section listed below for additional information about configuring and installing your particular model. Drive models ST19171N ST19171W ST19171WC ST19171WD ST19171DC Page 32 36 41 General information The following general information topics are discussed: · · · · · · · · SCSI ID jumpers Drive termination Terminator power Interface drivers and data path width notes Other applicable jumper options Providing adequate cooling Mounting the drive and connecting cables* Formatting the drive *This mounting procedure does not apply to WC or DC model drives. To mount a WC or DC drive, plug the drive into the system's single connector attachment (SCA) position on the system's back panel. Barracuda 9 Installation Guide, Rev. B 21 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-numbered ID available; therefore the lower-numbered SCSI IDs are normally used for other SCSI devices such as this Barracuda disc drive. Most SCSI controllers (host adapters) allow you to skip a SCSI ID. For example, you can have ID0, ID1, and ID3 (skipping ID2). Other controllers do not allow this so be sure to refer to your system or controller user's manual for details about its requirements for proper SCSI device installation. Most Barracuda disc drives are factory set with the SCSI ID set at 0. To change the SCSI ID, refer to the appropriate drive section for your model. If, after completing the installation process, the drive's LED does not show on/off activity when the host is trying to communicate with the drive, a duplicate SCSI ID may be the problem. If this is the case, change the ID so that each device on the SCSI chain has its own unique ID. Also check your system or controller user's manual to ensure that you have not violated its SCSI ID numbering recommendations. Drive termination If you are installing a Barracuda drive in a system that has other SCSI devices installed, terminate only the end devices on the SCSI chain. A SCSI "device" is any disc drive, scanner, tape backup unit, or other piece of hardware connected to your system using the SCSI bus. 22 Barracuda 9 Installation Guide, Rev.
