  • Page 17: General Description

    Barracuda 9LP Installation Guide, Rev. E General description Barracuda 9LP SCSI disc drives are high-speed, random-access digital-data storage devices. The drive is a component for installation in an enclosure designed for the drive. This is often a rack within the system or an external enclosure designed to house one or more disc drives or other peripheral units.

  • Page 23: Initial Setup Information

    Barracuda 9LP Installation Guide, Rev. E Initial setup information The general information beginning on this page applies to all of the Barracuda 9LP drive models. After reading the general infor- mation topics, refer to the appropriate drive-specific section listed below for additional information about configuring and installing your particular model.
  • Page 24 SCSI ID jumpers Each device on the SCSI chain must have a unique SCSI ID. The host system’s SCSI controller usually uses the ID that has the highest priority interrupt in the SCSI I/O system. This is always ID7. ID0 is lowest priority in an 8-bit I/O system. ID8 is lowest priority in a 16-bit I/O system.
  • Page 25 Barracuda 9LP Installation Guide, Rev. E 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.

  • Page 33 Barracuda 9LP Installation Guide, Rev. E Providing adequate cooling The enclosure design must ensure adequate cooling for the drive. The maximum ambient air temperature around the drive should not exceed 50 C. However, to achieve maximum reliabil- ity, the ambient temperature should be about 15 C below this value most of the time.
